  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.

    All Methods Instance Methods Concrete Methods
    Modifier and Type | Method and 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.
