Constructor Detail

FastIntBuffer

public FastIntBuffer()

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

FastIntBuffer

public FastIntBuffer(int size)

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

Parameters:

size - the initial size.

Throws:

java.lang.IllegalArgumentException - if size is negative.

Method Detail

append

public FastIntBuffer append(int[] array,
                            int off,
                            int len)

Appends int array to buffer.

append

public FastIntBuffer append(int[] array)

Appends int array to buffer.

append

public FastIntBuffer append(int element)

Appends single int to buffer.

append

public FastIntBuffer append(FastIntBuffer buff)

Appends another fast buffer to this one.

size

public int size()

Returns buffer size.

isEmpty

public boolean isEmpty()

Tests if this buffer has no elements.

index

public int index()

Returns current index of inner int array chunk. Represents the index of last used inner array chunk.

offset

public int offset()
