meet

public void meet(Filter node)

Specified by:

meet in interface QueryModelVisitor<RuntimeException>

Overrides:

meet in class QueryModelVisitorBase<RuntimeException>

meetBinaryTupleOperator

protected void meetBinaryTupleOperator(BinaryTupleOperator node)

Description copied from class: QueryModelVisitorBase

Method called by all meet methods with a BinaryTupleOperator node as argument. Forwards the call to #meetTupleExpr by default.

Overrides:

meetBinaryTupleOperator in class QueryModelVisitorBase<RuntimeException>

Parameters:

node - The node that is being visited.

meetBinaryValueOperator

protected void meetBinaryValueOperator(BinaryValueOperator node)

Description copied from class: QueryModelVisitorBase

Method called by all meet methods with a BinaryValueOperator node as argument. Forwards the call to #meetValueExpr by default.

Overrides:

meetBinaryValueOperator in class QueryModelVisitorBase<RuntimeException>

Parameters:

node - The node that is being visited.

meetUnaryTupleOperator

protected void meetUnaryTupleOperator(UnaryTupleOperator node)

Description copied from class: QueryModelVisitorBase

Method called by all meet methods with a UnaryTupleOperator node as argument. Forwards the call to #meetTupleExpr by default.

Overrides:

meetUnaryTupleOperator in class QueryModelVisitorBase<RuntimeException>

Parameters:

node - The node that is being visited.

meetUnaryValueOperator

protected void meetUnaryValueOperator(UnaryValueOperator node)

Description copied from class: QueryModelVisitorBase

Method called by all meet methods with a UnaryValueOperator node as argument. Forwards the call to #meetValueExpr by default.

Overrides:

meetUnaryValueOperator in class QueryModelVisitorBase<RuntimeException>

Parameters:

node - The node that is being visited.

meetNode

protected void meetNode(QueryModelNode node)

Description copied from class: QueryModelVisitorBase

Method called by all of the other meet methods that are not overridden in subclasses. This method can be overridden in subclasses to define default behaviour when visiting nodes. The default behaviour of this method is to visit the node's children.

Overrides:

meetNode in class QueryModelVisitorBase<RuntimeException>

Parameters:

node - The node that is being visited.
