Ast.VariadicParameter Class

Namespace: Ast
Superclasses: AstNodeProperties

Represents the variadic_parameter nodes in the syntax tree of your code

Since R2026a

Description

The PQL class VariadicParameter represents the node variadic_parameter in the syntax tree of your code.

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 Example

Predicates	Description	Example
`is(VariadicParameter &param)`	The `is` predicate identifies syntax nodes for the variadic parameter (`...`) in function parameter lists. Example: void foo(int a, ...); The tree-sitter node `variadic_parameter` matches the `variadic_parameter` node corresponding to the `...` in the function parameter list.	This example demonstrates using the `VariadicParameter.is` predicate to find variadic parameters ("...") in function declarations. Example `C++` code that will trigger the rule: void foo(int a, ...); void bar(...); rule CheckVariadicParameterIs = { defectVariadic } defect defectVariadic = when Cpp.VariadicParameter.is(&vp) and vp.nodeText(&txt) raise "Found variadic parameter: "{txt}"" on vp
`isa(Cpp.Node.Node node, VariadicParameter &cast)`	The `is` predicate identifies syntax nodes for the variadic parameter (`...`) in function parameter lists. Example: void foo(int a, ...); The tree-sitter node `variadic_parameter` matches the `variadic_parameter` node corresponding to the `...` in the function parameter list.	This example demonstrates using the `VariadicParameter.is` predicate to find variadic parameters ("...") in function declarations. Example `C++` code that will trigger the rule: void foo(int a, ...); void bar(...); rule CheckVariadicParameterIs = { defectVariadic } defect defectVariadic = when Cpp.VariadicParameter.is(&vp) and vp.nodeText(&txt) raise "Found variadic parameter: "{txt}"" on vp

is(VariadicParameter &param)

The is predicate identifies syntax nodes for the variadic parameter (...) in function parameter lists.

Example:

void foo(int a, ...);

The tree-sitter node variadic_parameter matches the variadic_parameter node corresponding to the ... in the function parameter list.

This example demonstrates using the VariadicParameter.is predicate to find variadic parameters ("...") in function declarations. Example C++ code that will trigger the rule:

void foo(int a, ...);
void bar(...);

rule CheckVariadicParameterIs = { defectVariadic }
defect defectVariadic =
    when
        Cpp.VariadicParameter.is(&vp)
        and vp.nodeText(&txt)
    raise "Found variadic parameter: "{txt}""
    on vp

isa(Cpp.Node.Node node, VariadicParameter &cast)

The is predicate identifies syntax nodes for the variadic parameter (...) in function parameter lists.

Example:

void foo(int a, ...);

The tree-sitter node variadic_parameter matches the variadic_parameter node corresponding to the ... in the function parameter list.

This example demonstrates using the VariadicParameter.is predicate to find variadic parameters ("...") in function declarations. Example C++ code that will trigger the rule:

void foo(int a, ...);
void bar(...);

rule CheckVariadicParameterIs = { defectVariadic }
defect defectVariadic =
    when
        Cpp.VariadicParameter.is(&vp)
        and vp.nodeText(&txt)
    raise "Found variadic parameter: "{txt}""
    on vp
