The %SYSTEM.OBJ class provides an interface for managing objects.
You can use it via the special $system object:
Do $system.OBJ.Load("MyFile.xml","ck")

Deprecated function, to close objects let them go out of scope.
Compile a class.Compiles the class classes, which can be a single class, a comma separated list, a subscripted array of class names, or include wild cards. If recurse is true then do not output the intial 'compiling' message or the compile report as this is being called inside another compile loop.
qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()
Compile all classes within this namespace. By default it will not compile classes mapped from another database unless the qualifier '/mapped=1' is provided.
qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()'
Invoke $system.OBJ.CompileAll for all the namespaces.
Compile a list of items specified in 'list' and separated by commas, or an array list("item.MAC")="" or wild cards. Each item on the list is sufixed by the type of item it is so to compile a class and a routine you could specify 'class.cls,routine.mac' The order of compilation is INT, CLS, MAC, CSR, CSP.
qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()
Compile all classes within the specified package.
qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()'
Compile all entries in this project.
qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()'
Delete a class.Delete the definition of class classes from this namespace which can be a single class, a comma separated list, a subscripted array of class names, or include wild cards.
Delete all the classes in this namespace.
Delete all the classes within the specified package. Note that this ignores the '/mapped' qualifier as if you know the exact package name it is assumed you wish to delete it even if the pacakge is mapped from another database.
Delete the named project from this namespace.
Decode and display an object error message to the console. If err is omitted, display the last generated object error.
Dump an object to the console.Write the in-memory state of a object referred to by oref to the console (the current device).
Set person = ##class(Person).%OpenId(22) Do $system.OBJ.Dump(person)
Export items as an XML fileEach of the items must have a type determined by an extension selected from the following list:
If exporting multiple items, separate them with commas, pass the items("item")="" as an array, or use wild cards.
- CLS - Classes
- CSP - Cache Server Pages
- CSR - Cache Rule files
- MAC - Macro routines
- INT - Non-macro routines
- BAS - Basic routines
- INC - Include files
- GBL - Globals
- PRJ - Studio projects
- OBJ - Compiled object code
- PKG - Package definitions
If the output filename is empty, matching items will be exported to the current device. If you pass qualifier '/recursive=1' then it will also export any related, e.g. include files included by a class or a superclass, the idea being that this will be a compilable set of items.
Export all the classes in this namespace as one large XML file.This function will loop through all the classes exporting them to the file filename. It will restrict which classes are exported based on the qspec
Export all the classes as individual XML files to a directory.This function will loop through all the classes exporting each one as an individual XML file named after the classname to the directory dirname. If you specify a Package then it will only export this package.
Export all the classes in this namespace as one large XML file.This function will loop through all the classes exporting them to the file filename. It will restrict which classes are exported based on the qspec If stream is passed in then the data is appended to this stream. If it is "" when called it will create a stream and return this.
Export a class to C++ files.Export class classname to C++ files in directory dirname.
Export a class to a Java file.Export class classname to a JAVA file in directory dirname.
Export classes in this package to Java.Search for classes in the package and export them. The search for classes respects the qspec passed. If the package is "*" then it will search for all classes in this namespace.
Export class package to a JAVA file in directory dirname.
Export a class to ODL file.Export class classname to ODL file with file name filename.
Export a set of classes in a package as an XML file.Export package package to an XML file with name filename.
Export a set of classes in a package in XML format to a stream.Export package package to an XML file with name filename. If stream is passed in then the data is appended to this stream. If it is "" when called it will create a stream and return this.
Export all items matching a pattern to an XML fileIf you pass a pattern of '*.cls' then all classes in this namespace will be exported, or a pattern of 'a*.mac' will export all MAC routines that start with the letter 'a' to be exported.
Export all items matching a pattern in XML format to a streamIf you pass a pattern of '*.cls' then all classes in this namespace will be exported, or a pattern of 'a*.mac' will export all MAC routines that start with the letter 'a' to be exported. If stream is passed in then the data is appended to this stream. If it is "" when called it will create a stream and return this.
Export items in XML format to a streamEach of the items must have a type determined by an extension selected from the following list:
If exporting multiple items, separate them with commas, pass the items("item")="" as an array, or use wild cards.
- CLS - Classes
- CSP - Cache Server Pages
- CSR - Cache Rule files
- MAC - Macro routines
- INT - Non-macro routines

- INC - Include files
- GBL - Globals

If the output filename is empty, matching items will be exported to the current device.
Return an array of classes in this namespace.Search for classes in this namespace and put their names into the local array items. The search for classes respects the qspec passed. It uses the following qualifiers
- /application=1/0 - Include application classes
- /system=1/0 - Include system classes (ones with class attribute 'system' set to something other than zero)
- /percent=1/0 - Include percent classes
- /mapped=1/0 - Include classes mapped from other databases or just classes in default databases
Return the current Object Concurrency mode.
This will return a list of classes the class compiler will include if the listed classes are compiled. The class can be a single class, a comma separated list, a subscripted array of class names, or include wild cards. It returns the list of classes that will be compiled in included based on the compile qspec.
Return an array of classes in this package.Search for classes in the package and put their names into the local array items. If the package is "*" then it will return for all classes in this namespace. It uses the qualfier in qspec /includesubpackages to determine if it searches inside a package to subpackages or not.
Get the default qualifiers for this namespace or this system. If system is true then this gets the default qualifiers for this system, otherwise it sets the default qualifiers for this namespace.
Return the current Object transaction mode.
Import and optionally compile all items in a directory.This will import all files found in a directory using the
Load so it should be able to detect most common formats. If you pass it the compile flag ('c') after loading it will also compile all these items. The other flags are the same as found in theLoad except for the dir which is the directory to load and the recurse which determines if this will look into subdirectories or not. You can limit the items it will import by specifying a wildcards value for example '*.xml' will only import files that end in XML.
qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()
Return if this class is up to date or not. If log is true then it will display a log of what it is checking in order to show if it is up to date or not. The type determines what it looks at to see if this class is up to date:
- 0 - Check timestamps on class, so even if a description was modified this will show the class as out of date
- 1 - Ignore changes to descriptions in checking up to date status, this is the default and is what the class compiler typically uses.
- 2 - Ignore changes to descriptions and method code in checking up to date status, this is useful to see if the class has 'structurally' changed in a way that would require a class referencing this via SQL to be recompiled
Return $$OK if this class name is valid, or an error message if it is not. If it is invalid it is typically because it contains characters that are not allowed in a class name or because it clashes with a class that already exists (different case in package say).
Load a file from disk into Cache.Load and, optionally compile (if 'c' flag is present), class definitions, CSP pages, routines or globals from the file file. It imports files exported in XML format, %RO format, CDL format, CSR/CSP files. Returns a comma separated list of the items it loaded in loadedlist, this also returns the item as a single subscript array in case there are more than 32k worth of them. You may give it a list of files to load separated with '*' symbols. If you pass listonly as true then it will not import anything but just list the items that exist in the files that you supply it.
If selecteditems is defined then this will contain a comma separated list of items to import (or a single subscripted array). It will only import items that are in this list from the file/s provided, so this provides a way to limit which items get imported.
qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()
Load all class definitions in a directory.Load and, optionally compile (if 'c' flag is present), all class definitions within directory dir, this includes all .XML files. If the recurse is true then it will include subdirectories. Returns a comma separated list of the items it loaded in loadedlist and the same data also as a loadedlist(name)="" in case the comma list is more than 32k. Note that this will only compile classes found in these XML files and no other types. If you want to be able to compile anything use the
ImportDir .
qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()
Import the specified language from CacheSys\bin\Errors_[language].xml and make this the current language. If language is not specified, then Upgrade the Object locale and import the current language.
Load a stream into Cache.Load and, optionally compile (if 'c' flag is present), class definitions, CSP pages, routines or globals from the stream stream. Returns an array of the items it loaded in loadedlist. If you pass listonly as true then it will not import anything but just list the items that exist in the stream that you supply.
If selecteditems is defined then this will contain a comma separated list of items to import (or a single subscripted array). It will only import items that are in this list from the stream provided, so this provides a way to limit which items get imported.
qspec is a list of flags or qualifiers which can be displayed with 'Do $system.OBJ.ShowQualifiers()' and 'Do $system.OBJ.ShowFlags()
Make a class or classes deployed. classes can be a single class, a comma separated list, a subscripted array of class names, or include wild cards. This will delete all the source code of the class from the disk. Once a class is in deployed mode, it can not be edited or exported or recompiled. You can still create subclasses of a deployed class and compile these.
Create a new object instance.Create a new object instance of type ClassName and return a reference (OREF) to it.
Using this method, you can dynamically create objects, that is you can determine what type of object to create at run-time.
For example:
Set obj = $System.OBJ.New("Person")
Open a persistent object instance.Load persistent object instance of type ClassName and with OID value oid from disk and return a reference (OREF) to it.
For example:
Set person = $System.OBJ.Open("Person",oid)
Open a persistent object instance.Load persistent object instance of type ClassName and with ID value id from disk and return a reference (OREF) to it.
For example:
Set person = $System.OBJ.OpenId("Person",22)
Turn output redirection on and off in the binding server.
Save all instances of %Library.Persistent in the process. Returns a status value.
Set the Object concurrency mode for the current process to a new value. Valid values are:
If a valid value is passed in then the concurrency mode for the current process will be set to that value and the previous concurrency mode value is returned. Otherwise the concurrency mode setting is left unchanged and pStatus will contain a %Status value describing the error and the current concurrency mode value is returned.
0 No concurrency controls 1 Atomic 2 Shared 3 Shared retained 4 Exclusive
Set the default flags for this namespace or this system. If system is true then this sets the default flags for this system, otherwise it sets the default flags for this namespace. If flags are set for this namespace these override any set for the system. These flags are combined with the built in defaults to create the defaults used. This method returns the new defaults after this change.
Set the default qualifiers for this namespace or this system. If system is true then this sets the default qualifiers for this system, otherwise it sets the default qualifiers for this namespace. If qualifiers are set for this namespace these override any set for the system. These qualifiers are combined with the built in defaults to create the defaults used. The argument group has been deprecated.
Set the object transaction mode for the current process to a new value. Valid values are:
If a valid value is passed in then the transaction mode for the current process will be set to that value and the previous transaction mode value is returned. Otherwise the transaction mode setting is left unchanged and pStatus will contain a %Status value describing the error and the current transaction mode value is returned.
0 No transactions used for Object filing 1 Use transactions for Object filing
Write all classes defined in this namespace to the console.The optional qspec argument is a qualifier string containing any of the following options:
/detail Show details. /hidden Show hidden classes. /mapped Show mapped classes. For example:
Do $System.OBJ.ShowClasses("/detail")
Display the list of flags used by the compiler.
Display the list of supported macros defined in the system.
Write all object instances in this process to the console.The optional qspec argument is a string containing any of the following characters:
d Show details. For example:
Do $System.OBJ.ShowObjects("d")
Display the list of qualifiers defined in the system. It also shows the default qualifiers defined at system level and at namespace levels. The argument group has been deprecated.
Display a list of all variables that contain a reference to this oref. If chkObj is set to 1, the properties of any varibles that contain an object reference will also be searched and displayed. Otherwise only non-object variables will be searched.
The list has the base $STACK level of the variable, the internal stack level (as shown by the %STACK utility), and the variable name.
Uncompile a class or classes. classes can be a single class, a comma separated list, a subscripted array of class names, or include wild cards.
Upgrade the class definition database in one namespace.
Upgrade the class definition database in all the namespaces.
Return the version number of the current object library.
