Package org.apache.cayenne.exp.parser
Class AggregateConditionNode
java.lang.Object
org.apache.cayenne.exp.Expression
org.apache.cayenne.exp.parser.SimpleNode
org.apache.cayenne.exp.parser.AggregateConditionNode
- All Implemented Interfaces:
- Serializable,- Node,- XMLSerializable
Superclass of aggregated conditional nodes such as NOT, AND, OR. Performs
 extra checks on parent and child expressions to validate conditions that are
 not addressed in the Cayenne expressions grammar.
- Since:
- 1.1

Method Details- 
pruneNodeForPrunedChildDescription copied from class:ExpressionReturns true if this node should be pruned from expression tree in the event a child is removed.- Overrides:
- pruneNodeForPrunedChildin class- SimpleNode
 
- 
transformExpressionDescription copied from class:ExpressionA recursive method called from "transform" to do the actual transformation.- Overrides:
- transformExpressionin class- Expression
- Returns:
- null, Expression.PRUNED_NODE or transformed expression.
 
- 
isValidParentDescription copied from class:SimpleNodeAdditional parent check that we can't handle properly in the grammar By default it just returns true.- Overrides:
- isValidParentin class- SimpleNode
- Parameters:
- n- potential parent node to check
- Returns:
- true if node could be set as a parent for the current node
 
-
