Ast.Virtual Class

Namespace: Ast
Superclasses: AstNodeProperties

Represents the virtual nodes in the syntax tree of your code

Since R2026a

Description

Virtual class represents the C++ syntax node virtual in your code and contains predicates to query properties and children of this node.

Type

Type	Raisable	Printable
`Virtual`	Yes	No

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(Virtual &virt)`	Retrieves syntax nodes of the type `Virtual` for your C/C++ code and stores it in `virt`.	rule CheckIs = { defectIs } defect defectIs = when Cpp.Virtual.is(&virt) and virt.nodeText(&txt) raise "Virtual.is matched: \"{txt}\""
`isa(Cpp.Node.Node node, Virtual &cast)`	Retrieves syntax nodes of the type `Virtual` from the nodes in `node`. Retrieval occurs if `node` is compatible with `Virtual` type.	rule CheckIsa = { defectIsa } defect defectIsa = when Ast.Node.is(&node, &,&,&) and Cpp.Virtual.isa(node, &virt) and virt.nodeText(&txt) raise "Virtual.isa matched: \"{txt}\""

is(Virtual &virt)

Retrieves syntax nodes of the type Virtual for your C/C++ code and stores it in virt.

rule CheckIs = { defectIs }
defect defectIs =
    when
        Cpp.Virtual.is(&virt)
        and virt.nodeText(&txt)
    raise "Virtual.is matched: \"{txt}\""

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

Retrieves syntax nodes of the type Virtual from the nodes in node. Retrieval occurs if node is compatible with Virtual type.

rule CheckIsa = { defectIsa }
defect defectIsa =
    when
        Ast.Node.is(&node, &,&,&)
        and Cpp.Virtual.isa(node, &virt)
        and virt.nodeText(&txt)
    raise "Virtual.isa matched: \"{txt}\""
