Constructor Detail

NodeFactoryBase

public NodeFactoryBase(java.lang.Class<T> nodeClass,
                       java.lang.Class<?>[] executionSignatures,
                       java.lang.Class<?>[][] nodeSignatures)

Method Detail

createNode

public abstract T createNode(java.lang.Object... arguments)

Description copied from interface: NodeFactory

Instantiates the node using the arguments array. The arguments length and types must suffice one of the returned signatures in NodeFactory.getNodeSignatures(). If the arguments array does not suffice one of the node signatures an IllegalArgumentException is thrown.

Specified by:

createNode in interface NodeFactory<T>

Parameters:

arguments - the argument values

Returns:

the instantiated node

getNodeClass

public final java.lang.Class<T> getNodeClass()

Description copied from interface: NodeFactory

Returns the node class that will get created by NodeFactory.createNode(Object...). The node class does not match exactly to the instantiated object but they are guaranteed to be assignable.

Specified by:

getNodeClass in interface NodeFactory<T>

getNodeSignatures

public final java.util.List<java.util.List<java.lang.Class<?>>> getNodeSignatures()

Description copied from interface: NodeFactory

Returns a list of signatures that can be used to invoke NodeFactory.createNode(Object...).

Specified by:

getNodeSignatures in interface NodeFactory<T>

getExecutionSignature

public final java.util.List<java.lang.Class<? extends Node>> getExecutionSignature()

Description copied from interface: NodeFactory

Returns a list of children that will be executed by the created node. This is useful for base nodes that can execute a variable amount of nodes.

Specified by:

getExecutionSignature in interface NodeFactory<T>
