-/**
-* 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
-*
