burlap.mdp.auxiliary.common.SinglePFTF

All Implemented Interfaces:

TerminalFunction

public class SinglePFTF
extends java.lang.Object
implements TerminalFunction

This class defines a terminal function that terminates in states where there exists a grounded version of a specified propositional function that is true in the state or alternatively, when there is a grounded version that is false in the state.

Constructor and Description
SinglePFTF(PropositionalFunction pf) Initializes the propositional function that will cause the state to be terminal when any Grounded version of pf is true.
SinglePFTF(PropositionalFunction pf, boolean terminateOnTrue) Initializes the propositional function that will cause the state to be terminal when any Grounded version of pf is true or alternatively false.

Method Summary

Modifier and Type	Method and Description
boolean	isTerminal(State s)
void	setTerminateOnTrue(boolean terminateOnTrue) Sets whether to be terminal state it is required for there to be a true grounded version of this class' propositional function or whether it is required for there to be a false grounded version.

Constructor Detail

SinglePFTF

public SinglePFTF(PropositionalFunction pf)

Initializes the propositional function that will cause the state to be terminal when any Grounded version of pf is true.

Parameters:

pf - the propositional function that must have a true grounded version for the state to be terminal.

SinglePFTF

public SinglePFTF(PropositionalFunction pf,
                  boolean terminateOnTrue)

Initializes the propositional function that will cause the state to be terminal when any Grounded version of pf is true or alternatively false.

Parameters:

pf - the propositional function that must have a true grounded version for the state to be terminal.

terminateOnTrue - when true requires a grounded version of pf to be true for the state to be terminal. When false requires a grounded version to be false to be terminal.

Method Detail

setTerminateOnTrue

public void setTerminateOnTrue(boolean terminateOnTrue)

Sets whether to be terminal state it is required for there to be a true grounded version of this class' propositional function or whether it is required for there to be a false grounded version.

Parameters:

terminateOnTrue - if true then there must be a true grounded prop; if false then there must be a false grounded prop.
