Method Detail

visit

public <X extends Exception> void visit(QueryModelVisitor<X> visitor)
                                 throws X extends Exception

Description copied from interface: QueryModelNode

Visits this node. The node reports itself to the visitor with the proper runtime type.

Throws:

X extends Exception

clone

public NaryJoin clone()

Description copied from interface: QueryModelNode

Returns a (deep) clone of this query model node. This method recursively clones the entire node tree, starting from this nodes.

Specified by:

clone in interface QueryModelNode

Specified by:

clone in interface TupleExpr

Overrides:

clone in class AbstractNaryTupleOperator

Returns:

A deep clone of this query model node.
