Member Function Documentation

EndOfStream()

virtual void v8::OutputStream::EndOfStream ( )

pure virtual

Notify about the end of stream.

Implemented in v8::internal::FileOutputStream.

Here is the caller graph for this function:

GetChunkSize()

virtual int v8::OutputStream::GetChunkSize ( )

inlinevirtual

Get preferred output chunk size. Called only once.

Definition at line 189 of file v8-profiler.h.

Here is the caller graph for this function:

WriteAsciiChunk()

virtual WriteResult v8::OutputStream::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.

Implemented in v8::internal::FileOutputStream.

Here is the caller graph for this function:

WriteHeapStatsChunk()

virtual WriteResult v8::OutputStream::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.
