[Java]
    TSBOfficeCreateTemporaryStreamEvent getOnCreateTemporaryStream();
    void setOnCreateTemporaryStream(TSBOfficeCreateTemporaryStreamEvent Value);
    TSBOfficeCreateTemporaryStreamEvent.Callback OnCreateTemporaryStream = new TSBOfficeCreateTemporaryStreamEvent.Callback() {
        public void TSBOfficeCreateTemporaryStreamEventCallback(TObject arg0, long arg1, TElOfficeCreateTemporaryStreamEventParams arg2) {
            //...
        }
    }

Parameters

ExpectedSize - expected size of the stream
Stream - the stream that is needed
FreeOnClose - set this parameter to True if the stream should be automatically freed

Description

This event is fired by TElOfficeDocument when a temporary stream is needed. The handler should create a stream object and pass it via the Stream parameter. Set FreeOnClose parameter to True if you don't want OnCloseTemporaryStream to be fired on stream closing.
