Constructor Detail

ClassFilterReteNode

public ClassFilterReteNode(java.lang.Class classType)

Class constructor.

Parameters:

classType - the class object that indicates which tokens can pass by this node.

Method Detail

getClassType

public java.lang.Class getClassType()

Returns the class object associated with this node.

Returns:

the class object associated with this node.

newObject

public void newObject(java.lang.Object obj)

Informs this node that an object has arrived. As the type check of the objects is being performed at the knowledge base, we will assume that this kind of node will always propagate the objects that arrive at it.

Parameters:

obj - the object that arrived at this node.

input - the input number of this node that is to receive the object.

newObject

public void newObject(java.lang.Object obj,
                      int input)

Informs this node that an object has arrived. As the type check of the objects is being performed at the knowledge base, we will assume that this kind of node will always propagate the objects that arrive at it.

Overrides:

newObject in class ReteNode

Parameters:

obj - the object that arrived at this node.

Returns:

true if this node can be activated with the given tokens; false otherwise.

toString

public java.lang.String toString()

Returns a string representation of this object. Useful for debugging.

Overrides:

toString in class java.lang.Object

Returns:

a string representation of this object.

getClassFilterSuccessors

public java.util.List getClassFilterSuccessors()

Returns the successors of this node.

Returns:

the successors of this node.
