Constructor Detail

AggregateSchema

public AggregateSchema(java.lang.String typeName)

Creates an AggregateSchema with a given type-name.

Parameters:

typeName - The name of this AggregateSchema.

Method Detail

getBaseSchema

public static ObjectSchema getBaseSchema()

Retrieve the generic base schema for all aggregates.

Returns:

the generic base schema for all aggregates.

newInstance

public AbsObject newInstance()
                      throws OntologyException

Creates an Abstract descriptor to hold an aggregate of the proper type.

Overrides:

newInstance in class TermSchema

OntologyException

validate

public void validate(AbsObject abs,
                     Ontology onto)
              throws OntologyException

Check whether a given abstract descriptor complies with this schema.

Overrides:

validate in class jade.content.schema.ObjectSchemaImpl

Parameters:

abs - The abstract descriptor to be checked

Throws:

OntologyException - If the abstract descriptor does not complies with this schema

descendsFrom

protected boolean descendsFrom(ObjectSchema s)

Return true if - s is the base schema for the XXXSchema class this schema is an instance of (e.g. s is ConceptSchema.getBaseSchema() and this schema is an instance of ConceptSchema) - s is the base schema for a super-class of the XXXSchema class this schema is an instance of (e.g. s is TermSchema.getBaseSchema() and this schema is an instance of ConceptSchema)

Overrides:

descendsFrom in class TermSchema

equals

public boolean equals(java.lang.Object o)

The difference between types of aggregates (such as SET and SEQUENCE) is quite fuzy. Therefore we don't throw a validation exception if a SET is found where a SEQUENCE is expected and VV.

Overrides:

equals in class jade.content.schema.ObjectSchemaImpl
