Package org.moeaframework.util.tree

Class Sequence

java.lang.Object
org.moeaframework.util.tree.Node
org.moeaframework.util.tree.Sequence
public class Sequence extends Node
The node for executing two or more expressions in sequence. The return value of the last expression is returned, and the return type should be specified using an appropriate constructor. Since the expressions are strongly typed, the type(s) specified in the constructor is important.
Node signature:
Name Type Description
Argument 1 User-Defined The first expression
Argument 2 User-Defined The second expression
Return Value User-Defined The return value of the last expression
