Class Property

java.lang.Object

net.sf.openschema.Property

public abstract class Property
extends Object

Properties to be checked among variables in the predicate. Properties should be moved to a XML on a format on their own in the future. However, lot of changes are foreseen here in the immediate future so it's easy to keep them in the current format. Properties are a strings in the openschema xml definition file (OpenSchema.xsd). The class Property is abstract and contains a parse static method that will translate the string into a tree of Property subclasses, defined with package access rights only.

Method Detail

variables

public abstract Set<String> variables()

Variables this property restricts. Should be used later on to implement optimizations in the CSP code in OpenSchema.

check

public abstract boolean check(Map<Object,Frame> vars,
                              Ontology ontology)

Check whether a map of variables to values verifies or not this property. The ontology is employed for ontological properties, such as "object-1 UNDER c-entity".

resolveAll

protected Set<Frame> resolveAll(net.sf.openschema.VarRef varRef,
                                Frame frame)

parse

public static Property parse(String s,
                             Set<String> vars)

Static parse method, this is the only way to create properties. The possible variables are given as a Set (from the predicate variables section) to tell variables from ground strings.
