Class ParameterNode  

java.lang.Object
  org.yajre.reteoo.TupleSource
      org.yajre.reteoo.ParameterNode

---

public final class ParameterNode

extends TupleSource

Receives Objects from an ObjectTypeNode, and creates a ReteTuple, passing the result to the following node.

The ParameterNode is the first node that works in terms of Tuples. An instance of ParameterNode exists for each root fact object parameter of each rule.

getTupleDeclarations

public final java.util.Set getTupleDeclarations()

Description copied from class: TupleSource

Retrieve the Set of org.yajre.spi.Declarations in the propagated Tuples.

Specified by:

getTupleDeclarations in class TupleSource

assert

protected final void assert(java.lang.Object obj,
                            org.yajre.WorkingMemory mem)
                     throws org.yajre.AssertionException

protected final void modify(java.lang.Object obj,
                            org.yajre.WorkingMemory mem)
                     throws org.yajre.ModificationException

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).
