Constructor Detail

FastBooleanBuffer

public FastBooleanBuffer()

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

FastBooleanBuffer

public FastBooleanBuffer(int size)

Creates a new boolean 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 FastBooleanBuffer append(boolean[] array,
                       int off,
                       int len)

Appends boolean array to buffer.

append

public FastBooleanBuffer append(boolean[] array)

append

public FastBooleanBuffer append(boolean element)

Appends single boolean to buffer.

append

public FastBooleanBuffer append(FastBooleanBuffer 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()
