Constructor Detail

ByteArrayHandle

public ByteArrayHandle(byte[] bytes)

Creates a random access byte stream to read from, and write to, the bytes specified by the byte[] argument.

ByteArrayHandle

public ByteArrayHandle(ByteBuffer bytes)

ByteArrayHandle

public ByteArrayHandle(int capacity)

Creates a random access byte stream to read from, and write to.

Parameters:

capacity - Number of bytes to initially allocate.

ByteArrayHandle

public ByteArrayHandle()
