Constructor Detail

FastFloatBuffer

public FastFloatBuffer()

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

FastFloatBuffer

public FastFloatBuffer(int size)

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

Parameters:

size - the initial size.

Throws:

java.lang.IllegalArgumentException - if size is negative.
