Class Inheritance

extends Object

org.eclipse.jetty.http.compression.HuffmanEncoder

Imports

java.nio.ByteBuffer, org.eclipse.jetty.http.HttpTokens

Used to encode strings Huffman encoding.

Characters are encoded with ISO-8859-1, if any multi-byte characters or control characters are present the encoder will throw EncodingException.
