de.tsl2.nano.h5.expression

Class RuleExpression<T extends Serializable>

java.lang.Object

de.tsl2.nano.bean.def.AbstractExpression<T>

de.tsl2.nano.h5.expression.RunnableExpression<T>

de.tsl2.nano.h5.expression.RuleExpression<T>

All Implemented Interfaces:

de.tsl2.nano.bean.def.IValueExpression<T>, de.tsl2.nano.core.cls.IAttribute<T>, Serializable, Comparable<de.tsl2.nano.core.cls.IAttribute<T>>

public class RuleExpression<T extends Serializable>
extends RunnableExpression<T>

Attribute providing the calculation of a Rule. This attribute can be connected to a 'real' bean-attribute to transfer the calculation value.
