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(SystemLibString &lib)`	The `is` predicate identifies nodes for standard C++ library headers in the syntax tree. Examples include `<vector>` and `<iostream>`. It matches `system_lib_string` nodes corresponding to included standard library headers. #include <vector> #include <iostream> // tree-sitter node: system_lib_string // The predicate matches the system_lib_string nodes corresponding to the included standard library headers. For instance, the `is` predicate matches `system_lib_string` nodes for `<vector>` and `<iostream>`, confirming these are recognized standard library includes in the analyzed code.	This example demonstrates using the `SystemLibString.is` predicate to find string literals that are represented in the AST as `SystemLibString` nodes. The C++ snippet below contains a `std::string` literal that will be matched by the rule. #include <string> int main() { std::string s = "hello world"; // This string is represented as a SystemLibString node return 0; } rule CheckSystemLibStringIs = { defectSystemLibStringIs } defect defectSystemLibStringIs = when Cpp.SystemLibString.is(&lib) and lib.nodeText(&txt) raise "Found SystemLibString via is(): "{txt}"" on lib
`isa(Cpp.Node.Node node, SystemLibString &cast)`	The `is` predicate identifies nodes for standard C++ library headers in the syntax tree. Examples include `<vector>` and `<iostream>`. It matches `system_lib_string` nodes corresponding to included standard library headers. #include <vector> #include <iostream> // tree-sitter node: system_lib_string // The predicate matches the system_lib_string nodes corresponding to the included standard library headers. For instance, the `is` predicate matches `system_lib_string` nodes for `<vector>` and `<iostream>`, confirming these are recognized standard library includes in the analyzed code.	This example demonstrates using the `SystemLibString.is` predicate to find string literals that are represented in the AST as `SystemLibString` nodes. The C++ snippet below contains a `std::string` literal that will be matched by the rule. #include <string> int main() { std::string s = "hello world"; // This string is represented as a SystemLibString node return 0; } rule CheckSystemLibStringIs = { defectSystemLibStringIs } defect defectSystemLibStringIs = when Cpp.SystemLibString.is(&lib) and lib.nodeText(&txt) raise "Found SystemLibString via is(): "{txt}"" on lib

is(SystemLibString &lib)

The is predicate identifies nodes for standard C++ library headers in the syntax tree. Examples include <vector> and <iostream>.

It matches system_lib_string nodes corresponding to included standard library headers.

#include <vector>
#include <iostream>

// tree-sitter node: system_lib_string
// The predicate matches the system_lib_string nodes corresponding to the included standard library headers.

For instance, the is predicate matches system_lib_string nodes for <vector> and <iostream>, confirming these are recognized standard library includes in the analyzed code.

This example demonstrates using the SystemLibString.is predicate to find string literals that are represented in the AST as SystemLibString nodes. The C++ snippet below contains a std::string literal that will be matched by the rule.

#include <string>
int main() {
    std::string s = "hello world"; // This string is represented as a SystemLibString node
    return 0;
}

rule CheckSystemLibStringIs = { defectSystemLibStringIs }
defect defectSystemLibStringIs =
    when
        Cpp.SystemLibString.is(&lib)
        and lib.nodeText(&txt)
    raise "Found SystemLibString via is(): "{txt}""
    on lib

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

The is predicate identifies nodes for standard C++ library headers in the syntax tree. Examples include <vector> and <iostream>.

It matches system_lib_string nodes corresponding to included standard library headers.

#include <vector>
#include <iostream>

// tree-sitter node: system_lib_string
// The predicate matches the system_lib_string nodes corresponding to the included standard library headers.

For instance, the is predicate matches system_lib_string nodes for <vector> and <iostream>, confirming these are recognized standard library includes in the analyzed code.

#include <string>
int main() {
    std::string s = "hello world"; // This string is represented as a SystemLibString node
    return 0;
}

rule CheckSystemLibStringIs = { defectSystemLibStringIs }
defect defectSystemLibStringIs =
    when
        Cpp.SystemLibString.is(&lib)
        and lib.nodeText(&txt)
    raise "Found SystemLibString via is(): "{txt}""
    on lib
