java.lang.Object

jade.content.lang.Codec

jade.content.lang.StringCodec

jade.content.lang.sl.SLCodec

All Implemented Interfaces:

java.io.Serializable

public class SLCodec
extends StringCodec

The codec class for the FIPA-SLn languages. This class implements the Codec interface and allows converting back and forth between strings and frames, according to the SL grammar. By default the class implements full SL grammar, otherwise the proper value must be used in the constructor.
