public final class RegexpExpression extends AbstractExpression
The string_expression
must have a string value. The pattern_value
is a
string literal or a string-valued input parameter that is a regular expression.

. This method can be used to optimize traversing
the children since a new list is not created every time Expression.children()
is called.
This does not traverse the Expression
sub-hierarchy, use a subclass of
AbstractTraverseChildrenVisitor
in order to traverse the entire sub-hierarchy.
