Class LazyAspectVariable<V extends IValue>

java.lang.Object

org.cyclops.integrateddynamics.api.evaluate.expression.VariableAdapter<V>

org.cyclops.integrateddynamics.core.part.aspect.LazyAspectVariable<V>

All Implemented Interfaces:

IVariable<V>, IVariableInvalidateListener, IAspectVariable<V>

public abstract class LazyAspectVariable<V extends IValue>
extends VariableAdapter<V>
implements IAspectVariable<V>

Variable for a specific aspect from a part that calculates its target value only maximum once per ticking interval. No calculations will be done if the value of this variable is not called.

Method Details

getTarget

public PartTarget getTarget()

Specified by:

getTarget in interface IAspectVariable<V extends IValue>

Returns:

The target of this aspect variable.

invalidate

public void invalidate()

Description copied from interface: IVariableInvalidateListener

Called when a variable was invalidated.

Specified by:

invalidate in interface IVariableInvalidateListener

Overrides:

invalidate in class VariableAdapter<V extends IValue>

getValue

public V getValue()
           throws EvaluationException

Specified by:

getValue in interface IVariable<V extends IValue>

Returns:

The current value of this variable.

Throws:

EvaluationException - If something went wrong while evaluating

getAspectProperties

protected IAspectProperties getAspectProperties()

getValueLazy

public abstract V getValueLazy()
                        throws EvaluationException

Calculate the current value for this variable. It will only be called when required.

Returns:

The current value of this variable.

Throws:

EvaluationException - If evaluation has gone wrong.
