Parameters

• parameter CONTENT;
XML element content "MIXED" for mixed="true" and "STRING" or "ESCAPE" for mixed="false". If CONTENT="STRING" (default) XML special characters are put in a CDATA section during XML export. If CONTENT="ESCAPE" XML special characters are escaped during XML export. If CONTENT="ESCAPE-C14N" XML special characters are escaped during XML export using the translate table, XMLC, specified for XML Canonicalizaton. The main difference is that CR is escaped as 
• parameter ENCODING = "base64";
Encoding to be used for XML serialization of a binary stream.
• parameter ESCAPE = "XML";
Controls the translate table used to escape content when CONTENT="MIXED" is specified.
• parameter LOCATION;
If STORAGE is "GLOBAL", this is the global node reference where the stream data is stored. For file streams this is the directory where the files are stored
• parameter MTOM = 1;
If MTOM is true, then the property that references this binary stream is available for optimization when using SOAP MTOM (Message Transmission Optimization Mechanism). The default for binary streams is true.
• parameter STORAGE;
This is the storage type of the stream - GLOBAL or OTHER.

Methods

• classmethod Delete(streamvalue) as %Status
• method GetObject(force As %Integer = 0) as %ObjectIdentity
This method obtains the state/id of the referenced object if swizzling has not occurred, it simply returns the stored state else it references the specified object force = an optional parameter, if its value is 1 then if the referenced object is an ID object it must return its ID, which may force it to file itself. No code for this method if the property is a datatype.
• method GetSwizzled() as %RegisteredObject
returns an oref, performing swizzling if necessary it returns "" ($$$NULLOREF) if there is no oref and the id=""
• method NewObject(type As %RawString = "") as %ObjectHandle
Creates a new object for the referenced property
• classmethod Open(streamvalue) as %RegisteredObject
• method Set(newvalue As %RawString) as %Status
Set the property to an oref value if the new oref is different from an old oref, the old object is closed
