com.aparapi.internal.reader.ByteReader

public class ByteReader
extends Object

Primarily used to parse various ClassFile structures. This class provides low level access to sequential bytes in a stream given stream.

Basically wraps a ByteBuffer and keeps track of the current offset. All requests on this ByteReader will be delegated to wrappedByteBuffer.
