Class BufferChecks

java.lang.Object
  extended by org.lwjgl.BufferChecks

public class BufferChecks
extends java.lang.Object

A class to check buffer boundaries in general. If there is unsufficient space in the buffer when the call is made then a buffer overflow would otherwise occur and cause unexpected behaviour, a crash, or worse, a security risk. Internal class, don't use.
