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.
