grab

public Frame grab()
           throws FrameGrabber.Exception

Description copied from class: FrameGrabber

Each call to grab stores the new image in the memory address for the previously returned frame.
IE.
grabber.grab() == grabber.grab()
This means that if you need to cache images returned from grab you should Frame.clone() the returned frame as the next call to grab will overwrite your existing image's memory.
Why?
Using this method instead of allocating a new buffer every time a frame is grabbed improves performance by reducing the frequency of garbage collections. Almost no additional heap space is typically allocated per frame.

Specified by:

grab in class FrameGrabber

Returns:

null grabs all images, get them with grabColor, grabDepth, and grabIR instead.

Throws:

FrameGrabber.Exception
