Member Function Documentation

EndOfStream()

virtual void EndOfStream ( )

pure virtual

Notify about the end of stream.

GetChunkSize()

virtual int GetChunkSize ( )

inlinevirtual

Get preferred output chunk size. Called only once.

WriteAsciiChunk()

virtual WriteResult WriteAsciiChunk ( char *  data, int  size  )

pure virtual

Writes the next chunk of snapshot data into the stream. Writing can be stopped by returning kAbort as function result. EndOfStream will not be called in case writing was aborted.

WriteHeapStatsChunk()

virtual WriteResult WriteHeapStatsChunk ( HeapStatsUpdate *  data, int  count  )

inlinevirtual

Writes the next chunk of heap stats data into the stream. Writing can be stopped by returning kAbort as function result. EndOfStream will not be called in case writing was aborted.
