Namespace: Cpp
Superclasses: AstNodeProperties

Represents the optional_parameter_declaration nodes in the syntax tree of your code

Since R2026a

Syntaxes

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 OptionalParameterDeclaration &optParamDecl)`	Finds syntax nodes of the type `OptionalParameterDeclaration` and returns them as `optParamDecl`. This represents a parameter declaration with a default value.
`isa(Cpp.Node.Node node)`	Checks if `node` is an `OptionalParameterDeclaration`.
`cast(Cpp.Node.Node node, required OptionalParameterDeclaration &cast)`	Finds `OptionalParameterDeclaration` nodes from `node` when compatible.
`type(OptionalParameterDeclaration self, Cpp.Node.Node &child)`	Matches the parameter type.
`declarator(OptionalParameterDeclaration self, Cpp.Node.Node &child)`	Matches the parameter declarator.
`defaultValue(OptionalParameterDeclaration self, Cpp.Node.Node &child)`	Matches the default value expression.
`msDeclspecModifier(OptionalParameterDeclaration self, Cpp.Node.Node &child)`	Matches a Microsoft `__declspec` modifier applied to the parameter.
`storageClassSpecifier(OptionalParameterDeclaration self, Cpp.Node.Node &child)`	Matches a storage class specifier applied to the parameter.
`typeQualifier(OptionalParameterDeclaration self, Cpp.Node.Node &child)`	Matches a type qualifier applied to the parameter.
`attributeDeclaration(OptionalParameterDeclaration self, Cpp.Node.Node &child)`	Matches an attribute declaration applied to the parameter.
`attributeSpecifier(OptionalParameterDeclaration self, Cpp.Node.Node &child)`	Matches an attribute specifier applied to the parameter.
`virtual(OptionalParameterDeclaration self, Cpp.Node.Node &child)`	Matches the `virtual` keyword when present.
`isEnclosedInOptionalParameterDeclaration(Cpp.Node.Node child)`	Checks if `child` appears inside an `OptionalParameterDeclaration`.
`getEnclosingOptionalParameterDeclaration(Cpp.Node.Node child, required OptionalParameterDeclaration &parent)`	Finds the nearest enclosing `OptionalParameterDeclaration` ancestor of `child`.
