Class ByteArray

java.lang.Object

com.pnfsoftware.jeb.util.io.ByteArray

public class ByteArray
extends Object

Primitive reader for little-endian byte arrays. Support for fixed-length primitive and variable-length LEB128-encoded primitives.

A max bound (see maxPosition()) can be set on the array. It can be be adjusted at any time after object creation. When a max bound is set, reading past that bound will generate a runtime exception. The bound is always relative to the full array length.
