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
