Class BufferChecks

  • public class BufferChecks
extends 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.
