org.drools.leaps
Class Token

java.lang.Object
  org.drools.leaps.Token

All Implemented Interfaces:: java.io.Serializable, Tuple

public class Token
extends java.lang.Object
implements Tuple, java.io.Serializable
extends java.lang.Object
implements Tuple, java.io.Serializable

this object wears multiple hats - Tuple and being main element that wraps fact handle on main leaps stack

Constructor Summary

Token(org.drools.leaps.LeapsWorkingMemory workingMemory, InternalFactHandle factHandle, PropagationContext propagationContext)


Method Summary

boolean dependsOn(FactHandle handle)
          Determine if this tuple depends upon a specified object.

boolean equals(java.lang.Object that)
          We always have only one Tuple per fact handle hence match on handle id

InternalFactHandle get(Declaration declaration)
          Returns the FactHandle for the given Declaration, which in turn specifcy the Column that they depend on.

InternalFactHandle get(int idx)
          Retrieve the value at position

LeapsRuleHandle getCurrentRuleHandle()


InternalFactHandle getDominantFactHandle()


InternalFactHandle[] getFactHandles()


PropagationContext getPropagationContext()


long getRecency()


WorkingMemory getWorkingMemory()
          Returns a reference to the WorkingMemory associated with this object.

int hashCode()


boolean hasNextRuleHandle()


boolean isResume()


LeapsRuleHandle nextRuleHandle()


void set(int idx, LeapsFactHandle factHandle)


void setActivation(Activation activation)
          Do nothing because this tuple never gets to agendaItem stage.

get

public InternalFactHandle get(int idx)

Retrieve the value at position

Specified by:: get in interface Tuple

Parameters:: position -
Returns:: The currently bound Object value.

get

public InternalFactHandle get(Declaration declaration)

Description copied from interface: Tuple

Returns the FactHandle for the given Declaration, which in turn specifcy the Column that they depend on.

Specified by:: get in interface Tuple

Parameters:: declaration - The Declaration which specifies the Column
Returns:: The FactHandle

dependsOn

public boolean dependsOn(FactHandle handle)

Determine if this tuple depends upon a specified object.
