+/**
+* This class adds streaming support to CTARMDmAdapter
+*
+* To enable streaming in your adapter:
+*
+* 1) Inherit from CTARMDmStreamAdapter
+* 2) Implement StreamingSupport (to return ETrue and set item size)
+* 3) Implement StreamType to return the stream support type
+*
+* Stream types:
+*
+* - EStreamToBuffer to get data in aObject argument
+* - EStreamToFile to get data in a file, file name is in iFileStoreFileName
+* - EStreamToNone to use streaming methods of CTARMDmAdapter
+*
+* 4) Use CTARMDmStreamAdapter::StreamCommittedL()
+*
+* StreamCommittedL will complete operation with call to the non-streaming method:
+*
+* - _UpdateLeafObjectL or
+* - _ExecuteCommandL
+*
