Class GroundedProp

java.lang.Object

burlap.mdp.core.oo.propositional.GroundedProp

All Implemented Interfaces:

java.lang.Cloneable

public class GroundedProp
extends java.lang.Object
implements java.lang.Cloneable

Propositional functions are defined to be evaluated on object parameters and this class provides a definition for a grounded propositional function; that is, it specifies specific object parameters on which the propositional function should be evaluated. The equals method correctly accounts for parameter order groups defined by this objects propositional function.

Constructor Detail

GroundedProp

public GroundedProp(PropositionalFunction p,
                    java.lang.String[] par)

Initializes a grounded propositional function

Parameters:

p - the propositional function that does the evaluation

par - the object name references on which the propositional function would be evaluated

Method Detail

clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object

isTrue

public boolean isTrue(OOState s)

Evaluates whether this grounded propositional function is true in the provided state.

Parameters:

s - the state on which to evaluate the grounded propositional function

Returns:

true if the propositional function bounded to this groundedProp's parameters is true in the specified state.

toString

public java.lang.String toString()

Returns a string representation of this grounded prop. If this groundedProp is specified by two parameters (ob1, ob2) then the returned format is: "PFName(ob1, ob2)"

Overrides:

toString in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object
