Cpp.FieldIdentifier Class

Namespace: Cpp
Superclasses: AstNodeProperties

Represents the field_identifier nodes in the syntax tree of your code

Since R2026a

Description

The PQL class Cpp.FieldIdentifier.FieldIdentifier represents the node field_identifier in the syntax tree of your code.

struct Point { int x, y; };
Point p; // Not a field_identifier
int a = p.x;

The expression p.x contains the field_identifier node corresponding to x. The class Cpp.FieldIdentifier.FieldIdentifier models such identifiers that are fields of larger types.

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(required FieldIdentifier &fieldIdentifier)`	Matches a `field_identifier` node and returns it as `fieldIdentifier`. Use this to directly find a `field_identifier` for further queries like text or location.	This PQL defect checks for any `field_identifier` nodes in the source. defect findFieldId = when Cpp.FieldIdentifier.is(&fi) and fi.nodeText(&txt) raise "Found field identifier: \"{txt}\"" on fi In this C++ code the defect finds the member name used in a member access expression. struct Point { int x, y; }; Point p; int a = p.x;
`cast(Cpp.Node.Node node, required FieldIdentifier &cast)`	Checks whether a given `Node` is a `field_identifier` and if so returns that node as `cast`. Use this when you have a generic `Node` and need to treat it as a `field_identifier`.	This PQL defect checks for a `field_identifier` that is reached via a generic node. defect castFromNode = when Cpp.Node.is(&n,&,&,&) and Cpp.FieldIdentifier.cast(n, &fi) and fi.nodeText(&txt) raise "Casted node to FieldIdentifier: \"{txt}\"" on fi In this C++ code the defect a `field_identifier`. struct Point { int x, y; }; Point p; int a = p.x;
`isa(Cpp.Node.Node node)`	Returns true if the supplied `Node` is a `field_identifier`. Use this to test node type.	This PQL defect checks whether a generic node is a `field_identifier`. defect isaFromNode = when Cpp.Node.is(&n,&,&,&) and Cpp.FieldIdentifier.isa(n) raise "Node is a FieldIdentifier" on me In this C++ code the defect a `field_identifier`. struct Point { int x, y; }; Point p; int a = p.x;

is(required FieldIdentifier &fieldIdentifier)

Matches a field_identifier node and returns it as fieldIdentifier. Use this to directly find a field_identifier for further queries like text or location.

This PQL defect checks for any field_identifier nodes in the source.

defect findFieldId =
    when
        Cpp.FieldIdentifier.is(&fi)
        and fi.nodeText(&txt)
    raise "Found field identifier: \"{txt}\""
    on fi

In this C++ code the defect finds the member name used in a member access expression.

struct Point { int x, y; };
Point p;
int a = p.x;

cast(Cpp.Node.Node node, required FieldIdentifier &cast)

Checks whether a given Node is a field_identifier and if so returns that node as cast. Use this when you have a generic Node and need to treat it as a field_identifier.

This PQL defect checks for a field_identifier that is reached via a generic node.

defect castFromNode =
    when
        Cpp.Node.is(&n,&,&,&)
        and Cpp.FieldIdentifier.cast(n, &fi)
        and fi.nodeText(&txt)
    raise "Casted node to FieldIdentifier: \"{txt}\""
    on fi

In this C++ code the defect a field_identifier.

struct Point { int x, y; };
Point p;
int a = p.x;

isa(Cpp.Node.Node node)

Returns true if the supplied Node is a field_identifier. Use this to test node type.

This PQL defect checks whether a generic node is a field_identifier.

defect isaFromNode =
    when
        Cpp.Node.is(&n,&,&,&)
        and Cpp.FieldIdentifier.isa(n)
    raise "Node is a FieldIdentifier"
    on me

In this C++ code the defect a field_identifier.

struct Point { int x, y; };
Point p;
int a = p.x;
