## 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:
  java.io.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.

    protected boolean pruneNodeForPrunedChild(java.lang.Object prunedChild)

  Description copied from class: `Expression`
  Returns true if this node should be pruned from expression tree in the event a child is removed.

  Overrides:
    `pruneNodeForPrunedChild` in class `SimpleNode`

### transformExpression

    protected java.lang.Object transformExpression(org.apache.commons.collections.Transformer transformer)

  Description copied from class: `Expression`
  A recursive method called from "transform" to do the actual transformation.

  Overrides:
    `transformExpression` in class `Expression`
  Returns:
    null, Expression.PRUNED_NODE or transformed expression.

### jjtSetParent

    public void jjtSetParent(Node n)

  Description copied from interface: `Node`
  This pair of methods are used to inform the node of its parent.

  Specified by:
    `jjtSetParent` in interface `Node`
  Overrides:
    `jjtSetParent` in class `SimpleNode`

### jjtAddChild

    public void jjtAddChild(Node n,
                            int i)

  Description copied from interface: `Node`
  This method tells the node to add its argument to the node's list of children.

  Specified by:
    `jjtAddChild` in interface `Node`
  Overrides:
    `jjtAddChild` in class `SimpleNode`
