      extended by 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. The inputs and outputs to this node are shown below:

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


Constructor Summary
Sequence()
          Constructs a new node for executing two expressions in sequence.
Sequence(Class<?>... types)
          Constructs a new node for executing a specified number of expressions in sequence.
Sequence(Class<?> type)
          Constructs a new node for executing two expressions in sequence.
Sequence(Class<?> type1, Class<?> type2)
          Constructs a new node for executing two expressions in sequence.
 
Method Summary
 Sequence copyNode()
          Returns a copy of this node, but without any children or parents assigned.
 Object evaluate(Environment environment)
          Evaluates this node in the context of the specified environment.
