Method Detail

bind

protected AbstractDecisionVariableEvaluationAccessor bind(IDecisionVariable variable,
                                                          EvaluationContext context)

Binds this accessor.

Parameters:

variable - the underlying variable

context - the evaluation context

Returns:

this (builder pattern)

clear

public void clear()

Description copied from class: EvaluationAccessor

Clears the accessor for reuse.

Overrides:

clear in class EvaluationAccessor

getVariable

public IDecisionVariable getVariable()

Description copied from class: EvaluationAccessor

Returns the underlying variable.

Specified by:

getVariable in class EvaluationAccessor

Returns:

the underlying variable (may be null)

notifyVariableChange

protected void notifyVariableChange(Value oldValue,
                                    IAssignmentState oldState,
                                    IValueChangeListener.ChangeKind kind)

Notifies the underlying variable about a change.

Parameters:

oldValue - the value before the change (may be null)

oldState - the old state of variable before the change

kind - the change kind

getReferenceValue
