Method Summary

java.util.List	decode(java.lang.String s, Ontology o) Decodes a given String, according to the given Content Language and obtains a t-uple of Frame objects.
java.lang.String	encode(java.util.List v, Ontology o) Encodes a t-uple of Frame objects into a Java String, according to this Content Language and Ontology by looking up the given ontology for the role played by symbols (i.e. whether they are concepts, actions or predicates).

Method Detail

encode

public java.lang.String encode(java.util.List v,
                               Ontology o)

Encodes a t-uple of Frame objects into a Java String, according to this Content Language and Ontology by looking up the given ontology for the role played by symbols (i.e. whether they are concepts, actions or predicates).

Parameters:

o - The ontology to use to lookup the roles for the various symbols.

Returns:

A Java string, representing the given frame according to this content language.

decode

public java.util.List decode(java.lang.String s,
                             Ontology o)
                      throws CodecException

Decodes a given String, according to the given Content Language and obtains a t-uple of Frame objects. This method can use the given ontology to distinguish among the different kinds of roles a symbol can play (i.e. Concept vs. Action vs. Predicate).

Parameters:

s - A string containing the representation of an ontological element, encoded according to this content language.

o - The ontology to use to lookup the roles for the various symbols.

Returns:

A List of frame, representing the given ontological elements.

Throws:

CodecException
