# 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`

Direct Known Subclasses:
  `ASTAnd`, `ASTNot`, `ASTOr`

public abstract class AggregateConditionNode extends SimpleNode
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.

- ## Method Summary

  Modifier and Type
  Method
  Description
  `void`
  `jjtAddChild(Node n, int i)`
  This method tells the node to add its argument to the node's list of children.
  `void`
  `jjtSetParent(Node n)`
  This pair of methods are used to inform the node of its parent.
  `protected boolean`
  `pruneNodeForPrunedChild(Object prunedChild)`
  Returns true if this node should be pruned from expression tree in the event a child is removed.
  `protected Object`
  `transformExpression(Function<Object,Object> transformer)`
  A recursive method called from "transform" to do the actual transformation.
