Class Fox::FXMemoryStream
In: rdoc-sources/FXMemoryStream.rb
Parent: FXStream

A FXMemoryStream is a stream that reads from (or writes to) a buffer of bytes in memory. That buffer may "owned" by either the application code or by the stream object itself. In the latter case, the stream object will dispose of the buffer contents when the stream is closed.

Public Instance methods

data:memory buffer to be used for the stream, or nil if the stream object should allocate its own buffer [String]
