class Fox::FXMemoryStream
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.

# File lib/fox16/iterators.rb, line 321 def FXMemoryStream.open(save_or_load, data, cont=nil) # :yields: theMemoryStream stream = FXMemoryStream.new(cont) if stream.open(save_or_load, data) if block_given? begin yield stream ensure stream.close end else stream end else # FXFileStream#open returned false, so report error raise FXStreamError.makeStreamError(stream.status) end end
Construct a new FXMemoryStream object with the specified data flow direction, data and container object. If an optional code block is given, it will be passed this memory stream as an argument, and the memory stream will automatically be closed when the block terminates. If no code block is provided, this method just returns the new memory stream in an opened state.
Raises FXStreamAllocError if some kind of memory allocation failed while initializing the stream.
Parameters:¶ ↑
save_or_load-
access mode, either
FXStreamSaveorFXStreamLoad[Integer] data-
memory buffer used for the stream, or
nilif the buffer is to be initially empty [String]. cont-
the container object, or
nilif there is none [FXObject]
