Class NodeFactoryImpl

java.lang.Object

oracle.toplink.essentials.internal.parsing.NodeFactoryImpl

All Implemented Interfaces:

NodeFactory

public class NodeFactoryImpl
extends Object
implements NodeFactory

INTERNAL

Purpose: Implements a node factory used by the EJBQLParser class.

Responsibilities:

• Create EJBQLParseTree instances for EJBQL SELECT-, UPDATE- and DELETE statements (see methods newSelectStatement, newUpdateStatement and newDeleteStatement).
• Any new method returns an instance of the appropriate Node subclass.
• The relationship to the child nodes passed as arguments are automatically initialized.
• Note, this implementation has a state managing the parse tree context and a list of parameter names for the current parse tree. This state needs to be initilized before the same node factory implementation instacne may be used to create a second parse tree (see methods initContext and initParameters).
• The implementation automatically adds the list of parameters to the created parse tree.
• The implementation automatically sets the parse tree context for any created major node.
