Constructor Detail

FastByteBuffer

public FastByteBuffer()

Creates a new byte buffer. The buffer capacity is initially 1024 bytes, though its size increases if necessary.

FastByteBuffer

public FastByteBuffer(int size)

Creates a new byte buffer, with a buffer capacity of the specified size, in bytes.

Parameters:

size - the initial size.

Method Detail

append

public FastByteBuffer append(byte[] array,
                             int off,
                             int len)

Appends byte array to buffer.

Parameters:

array - the array

off - the off

len - the len
