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<UnsupportedRdbmsOperatorException>

Parameters:

arg - The node that is being visited.

Throws:

UnsupportedRdbmsOperatorException

Throws:

UnsupportedRdbmsOperatorException

time

protected SqlExpr time(ValueExpr arg)
                throws UnsupportedRdbmsOperatorException

Throws:

UnsupportedRdbmsOperatorException

type

protected SqlExpr type(ValueExpr arg)
                throws UnsupportedRdbmsOperatorException

Throws:

UnsupportedRdbmsOperatorException

uri

protected SqlExpr uri(ValueExpr arg)
               throws UnsupportedRdbmsOperatorException

Throws:

UnsupportedRdbmsOperatorException

zoned

protected SqlExpr zoned(ValueExpr arg)
                 throws UnsupportedRdbmsOperatorException

Throws:
