pack-priv void acceptChildren(Visitor v) throws StandardException

Overrides org.apache.derby.impl.sql.compile.DDLStatementNode.acceptChildren.

Doc from org.apache.derby.impl.sql.compile.QueryTreeNode.acceptChildren.

Accept a visitor on all child nodes. All sub-classes that add fields that should be visited, should override this method and call accept(v) on all visitable fields, as well as super.acceptChildren(v) to make sure all visitable fields defined by the super-class are accepted too.

Parameters
v:Visitor
