Member predicate NullLiteral::getAPrimaryQlClass
Gets the name of a primary CodeQL class to which this element belongs.
For most elements, this is simply the most precise syntactic category to
which they belong; for example, AddExpr
is a primary class, but
BinaryOperation
is not.
If no primary classes match, this predicate has no result. If multiple primary classes match, this predicate can have multiple results.
See also getPrimaryQlClasses
, which is better to use in most cases.
