Class C2BConverter

java.lang.Object
  org.apache.tomcat.util.buf.C2BConverter

public final class C2BConverter

extends java.lang.Object

Efficient conversion of character to bytes. This uses the standard JDK mechansim - a writer - but provides mechanisms to recycle all the objects that are used. It is compatible with JDK1.1 and up, ( nio is better, but it's not available even in 1.2 or 1.3 )

Constructor Summary

C2BConverter(ByteChunk output, java.lang.String encoding)
Create a converter, with bytes going to a byte buffer

C2BConverter(java.lang.String encoding)
Create a converter

Method Summary

void	convert(char c) Generate the bytes using the specified encoding
void	convert(char[] c, int off, int len) Generate the bytes using the specified encoding
void	convert(MessageBytes mb) Convert a message bytes chars to bytes
void	convert(java.lang.String s) Generate the bytes using the specified encoding
void	flushBuffer() Flush any internal buffers into the ByteOutput or the internal byte[]
ByteChunk	getByteChunk()
java.lang.String	getEncoding()
void	recycle() Reset the internal state, empty the buffers.
void	setByteChunk(ByteChunk bb)

C2BConverter

public C2BConverter(java.lang.String encoding)
             throws java.io.IOException

Create a converter

Method Detail

getByteChunk

public ByteChunk getByteChunk()

getEncoding

public java.lang.String getEncoding()

setByteChunk

public void setByteChunk(ByteChunk bb)

recycle
