Constructor Detail

FastCharBuffer

public FastCharBuffer()

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

FastCharBuffer

public FastCharBuffer(int size)

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

Parameters:

size - the initial size.

Throws:

java.lang.IllegalArgumentException - if size is negative.
