• property %Mode as %String(TRUNCATE=1) [ ReadOnly ];

• property %ReadLineMode as %Boolean [ ReadOnly ];

• property IsTemp as %Boolean;

• property LastModified as %TimeStamp [ Calculated ];

• method Close(Output pSC As %Status) as %Boolean

Close the current stream

• method ExternalByteSeek(pBytePos As %Integer, Output pSC As %Status) as %Boolean

• method ExternalByteSizeGet() as %Integer

This is a Get accessor method for the ExternalByteSize property.

• method ExternalByteTruncateAt(pBytePos As %Integer, Output pSC As %Status) as %Boolean

• method Flush(Output pSC As %Status)

Ensure that any data already written to the stream buffer are actually sent to the stream.

• method LastModifiedGet() as %TimeStamp

This is a Get accessor method for the LastModified property.

• classmethod NewTempFilename(tExt As %String = "", pUseTempDir As %Boolean = 0) as %String

Create a new, unused filename. By default, the returned filename will have no directory component and will have the default file extension specified in DEFTEMPFILEEXT. If tExt is specified, this will be used as the file extension. If pUseTempDir is true, then the filename will include the current temporary directory for the namespace in which the method is called.

• method Open(pName As %String = "", pMode As %String = "R", ByRef pTimeout As %Numeric = 0, pCharEncoding As %String = "Native", Output pSC As %Status) as %Boolean

• method Read(pMaxReadLen As %Integer, ByRef pTimeout As %Numeric = -1, Output pSC As %Status) as %String

Read until pMaxReadLen chars are gotten or pTimeout expires On return, if pTimeout is unchanged it means the full timeout period expired. If the timeout period expired and the returned string is shorter than pMaxReadLen, then AtEnd will be 1.

• method ReadLine(pMaxReadLen As %Integer, ByRef pTimeout As %Numeric = -1, Output pSC As %Status, ByRef pLineTerminator As %String = ..LineTerminator) as %String

Read until pMaxReadLen chars are gotten, pTimeout expires, or a LineTerminator character is found. On return, if pTimeout=0 it means no timeout occurred. If pTimeout=0 and the returned string contains the full pMaxReadLen characters, it means no LineTerminator was encountered yet, even if the following character would be a LineTerminator. If pTimeout=0 and the returned string is shorter than pMaxReadLen, then either a LineTerminator or the End Of Stream (AtEnd = 1) was encountered. If pLineTerminator is defined, then the line is read until one of the given characters is encountered. On return, pLineTerminator contains the encountered character(s) if any.

• method Seek(pPosition As %Integer = 1, Output pSC As %Status) as %Boolean

• method SizeGet() as %Integer

Return the current character size of the data stream.

• method TruncateAt(pPosition As %Integer, Output pSC As %Status) as %Boolean

• method Write(pData As %String = "", pFlush As %Boolean, Output pSC As %Status)

Write pData to the stream buffer. If pFlush is True, ensure that the data are actually sent to the stream.
