This class defines these predicates that act on the objects of this class. In addition, objects of this class can access the predicates defined by the base class AstNodeProperties. An object of this class is an object of AstNodeProperties class.

Predicates	Description
`is(required PreprocDefined &preprocDefined)`	Finds syntax nodes of type `PreprocDefined`. This represents a `defined(MACRO)` expression used in preprocessor conditions.
`isa(Cpp.Node.Node node)`	Checks whether `node` is a `PreprocDefined`.
`cast(Cpp.Node.Node node, required PreprocDefined &cast)`	Finds `PreprocDefined` nodes from `node` when compatible.
`identifier(PreprocDefined self, Cpp.Node.Node &child)`	Matches the macro identifier tested by the `defined` operator.
`isEnclosedInPreprocDefined(Cpp.Node.Node child)`	Checks if `child` appears inside a `PreprocDefined`.
`getEnclosingPreprocDefined(Cpp.Node.Node child, required PreprocDefined &parent)`	Finds the nearest enclosing `PreprocDefined` ancestor.
