//...//

// save state
Blob blob_state = new Blob();
object.SaveState(blob_state);

// change the node state
//...//

// restore state
blob_state.SeekSet(0);	// returning the carriage to the start of the blob
object.RestoreState(blob_state);

Arguments

Stream stream - Stream smart pointer.

Return value

true on success; otherwise, false.

bool RestoreState ( Stream stream ) #

Restores an object state from the stream.

Restoring from the stream requires creating a blob to save into and saving the state using the saveState() method:

Source code (C#)

// initialize a node and set its state
//...//

// save state
Blob blob_state = new Blob();
object.SaveState(blob_state);

// change the node state
//...//

// restore state
blob_state.SeekSet(0);	// returning the carriage to the start of the blob
object.RestoreState(blob_state);

Arguments

Stream stream - Stream smart pointer.

Return value

true on success; otherwise, false.
