StreamPeerBuffer

Inherits: StreamPeer < RefCounted < Object

A stream peer used to handle binary data streams.

描述

A data buffer stream peer that uses a byte array as the stream. This object can be used to handle binary data from network sessions. To handle binary data stored in files, FileAccess can be used directly.

A StreamPeerBuffer object keeps an internal cursor which is the offset in bytes to the start of the buffer. Get and put operations are performed at the cursor position and will move the cursor accordingly.

Method Descriptions

void clear ( )

Clears the data_array and resets the cursor.

StreamPeerBuffer duplicate ( ) const

Returns a new StreamPeerBuffer with the same data_array content.

int get_position ( ) const

Returns the current cursor position.

int get_size ( ) const

Returns the size of data_array.

void resize ( int size )

Resizes the data_array. This doesn't update the cursor.

void seek ( int position )

Moves the cursor to the specified position. position must be a valid index of data_array.
