Class QueryTreeNodeVector<E extends QueryTreeNode>

java.lang.Object

org.apache.derby.impl.sql.compile.QueryTreeNode

org.apache.derby.impl.sql.compile.QueryTreeNodeVector<E>

All Implemented Interfaces:

java.lang.Iterable<E>, Visitable

Direct Known Subclasses:

FromList, OrderedColumnList, PredicateList, ResultColumnList, SubqueryList, TableElementList, ValueNodeList, WindowList

class QueryTreeNodeVector<E extends QueryTreeNode>
extends QueryTreeNode
implements java.lang.Iterable<E>

QueryTreeNodeVector is the root class for all lists of query tree nodes. It provides a wrapper for java.util.ArrayList. All lists of query tree nodes inherit from QueryTreeNodeVector.
