int writerCount ( ) const Get current number of open CompressedVectorWriter objects writing to ImageFile. CompressedVectorWriter objects that still exist, but are in the closed state aren't counted. CompressedVectorWriter objects are created by the CompressedVectorNode::writer function. Precondition: This ImageFile must be open (i.e. isOpen()). Postcondition: No visible state is modified. Returns: The current number of open CompressedVectorWriter objects writing to ImageFile. Exceptions: E57_ERROR_IMAGEFILE_NOT_OPEN E57_ERROR_INTERNAL All objects in undocumented state See also: SourceDestBufferFunctions.cpp example, CompressedVectorNode::writer, CompressedVectorWriter
