Class Utf32Reader

java.lang.Object
  java.io.Reader
      com.fasterxml.aalto.in.Utf32Reader

All Implemented Interfaces:

java.io.Closeable, java.lang.Readable

public final class Utf32Reader
extends java.io.Reader

Since JDK does not come with UTF-32/UCS-4, let's implement a simple decoder to use.

Field Summary

protected byte[]	mBuffer
protected java.io.InputStream	mIn
protected int	mLength
protected int	mPtr

Fields inherited from class java.io.Reader

Constructor Summary

Utf32Reader(ReaderConfig cfg, java.io.InputStream in, byte[] buf, int ptr, int len, boolean isBigEndian)

Method Summary

void	close()
void	freeBuffers()
int	read() Although this method is implemented by the base class, AND it should never be called by Woodstox code, let's still implement it bit more efficiently just in case
