Class CustomMutexType

Holds if fc is a call that always locks mutex arg of this type.

Holds if fc is a call that tries to lock mutex arg of this type, but may return without success.

Holds if fc is a call that unlocks mutex arg of this type.

Gets a detailed string representation explaining the AST of this type (with all specifiers and nested constructs such as pointers). This is intended to help debug queries and is a very expensive operation; not to be used in production queries.

Gets the source of this element: either itself or a macro that expanded to this element.

Holds if this element may be from source. This predicate holds for all elements, except for those in the dummy file, whose name is the empty string. The dummy file contains declarations that are built directly into the compiler.

Gets the name of a primary CodeQL class to which this element belongs.

Gets a specifier of this type, recursively looking through typedef and decltype. For example, in the context of typedef const int *restrict t, the type volatile t has specifiers volatile and restrict but not const since the const is attached to the type being pointed to rather than the pointer itself.

Gets as many places as possible where this type is used by name in the source after macros have been replaced (in particular, therefore, this will find type name uses caused by macros). Note that all type name uses within instantiations are currently excluded - this is too draconian in the absence of indexing prototype instantiations of functions, and is likely to improve in the future. At present, the method takes the conservative approach of giving valid type name uses, but not necessarily all type name uses.

Gets the alignment of this type in bytes.

Gets an attribute of this type.

Gets the closest Element enclosing this one.

Gets the primary file where this element occurs.

Gets the primary location of this element.

Gets a call that locks or tries to lock any mutex of this type.

Gets a call that always locks any mutex of this type.

Gets the name of this type.

Gets the parent scope of this Element, if any. A scope is a Type (Class / Enum), a Namespace, a BlockStmt, a Function, or certain kinds of Statement.

Gets the pointer indirection level of this type.

Gets a comma-separated list of the names of the primary CodeQL classes to which this element belongs.

Gets the size of this type in bytes.

Gets a call that tries to lock any mutex of this type, by may return without success.

Gets this type after typedefs have been resolved.

Gets a call that unlocks any mutex of this type.

Gets this type after specifiers have been deeply stripped and typedefs have been resolved.

Holds if this type is called name.

Holds if this declaration has a specifier called name, recursively looking through typedef and decltype. For example, in the context of typedef const int *restrict t, the type volatile t has specifiers volatile and restrict but not const since the const is attached to the type being pointed to rather than the pointer itself.

Internal – should be protected when QL supports such a flag. Subtypes override this to recursively get specifiers that are not attached directly to this @type in the database but arise through type aliases such as typedef and decltype.

Holds if this type involves a reference.

Holds if this type involves a template parameter.

Holds if this element is affected in any way by a macro. All elements that are totally or partially generated by a macro are included, so this is a super-set of isInMacroExpansion.

Holds if this type is const.

Holds if this type is constant and only contains constant types. For instance, a char *const is a constant type, but not deeply constant, because while the pointer can’t be modified the character can. The type const char *const* is a deeply constant type though - both the pointer and what it points to are immutable.

Holds if this type is constant and only contains constant types, excluding the type itself. It is implied by Type.isDeeplyConst() and is just used to implement that predicate. For example, const char *const is deeply constant and deeply constant below, but const char * is only deeply constant below (the pointer can be changed, but not the underlying char). char *const is neither (it is just const).

Holds if this Element is a part of a template instantiation (but not the template itself).

Holds if this Element is part of a template template (not if it is part of an instantiation of template). This means it is represented in the database purely as syntax and without guarantees on the presence or correctness of type-based operations such as implicit conversions.

Holds if this element comes from a macro expansion. Only elements that are entirely generated by a macro are included - for elements that partially come from a macro, see isAffectedByMacro.

Holds if this type is volatile.

Holds if fc is n call that locks or tries to lock mutex arg of this type.

Holds if this type refers to type t (by default, a type always refers to itself).

Holds if this type refers to type t directly.

Gets this type with any typedefs resolved. For example, given typedef C T, this would resolve const T& to const C&. Note that this will only work if the resolved type actually appears on its own elsewhere in the program.

Gets this type after any top-level specifiers and typedefs have been stripped.

Gets the type stripped of pointers, references and cv-qualifiers, and resolving typedefs. For example, given typedef const C& T, stripType returns C.

Gets a textual representation of this element.
