Query operators

Syntax

QueryOperator :
.. QualifiedIdentifier
. ( ListExpression^allowIn )

Descendants operator

o..x

Semantics

The descendants operator o..x looks at o for the meta::descendants() method and returns the result of invoking that method with the given identifier key.

Filter operator

o.(*.name.startsWith("A"))

Semantics

The filter operator o.(...) looks at o for the meta::filter() method and creates a wildcard * binding inside the parenthesized expression that represents the element being tested. The parenthesized expression must return a boolean and represents an activation.
