Represents a function declaration or definition.

Since a given function can be declared several times in a program, there may be several FunctionDecls that correspond to that function. Only one of those FunctionDecls will be found when traversing the list of declarations in the context of the FunctionDecl (e.g., the translation unit); this FunctionDecl contains all of the information known about the function. Other, previous declarations of the function are available via the getPreviousDecl() chain.

Retrieve the body (definition) of the function.

The function body might be in any of the (re-)declarations of this function. The variant that accepts a FunctionDecl pointer will set that function declaration to the actual declaration containing the body (if there is one). NOTE: For checking if there is a body, use hasBody() instead, to avoid unnecessary AST de-serialization of the body.

◆ getBuiltinID()

Returns a value indicating whether this function corresponds to a builtin function.

The function corresponds to a built-in function if it is declared at translation scope or within an extern "C" block and its name matches with the name of a builtin. The returned value will be 0 for functions that do not correspond to a builtin, a value of type Builtin::ID if in the target-independent range [1,Builtin::First), or a target-specific builtin value.

Parameters: ConsiderWrapperFunctions If true, we should consider wrapper functions as their wrapped builtins. This shouldn't be done in general, but it's useful in Sema to diagnose calls to wrappers based on their semantics.

Retrieves the function template that is described by this function declaration.

Every function template is represented as a FunctionTemplateDecl and a FunctionDecl (or something derived from FunctionDecl). The former contains template properties (such as the template parameter lists) while the latter contains the actual description of the template's contents. FunctionTemplateDecl::getTemplatedDecl() retrieves the FunctionDecl that describes the function template, getDescribedFunctionTemplate() retrieves the FunctionTemplateDecl from a FunctionDecl.

If this function is an instantiation of a member function of a class template specialization, retrieves the function from which it was instantiated.

This routine will return non-NULL for (non-templated) member functions of class templates and for instantiations of function templates. For example, given:

template<typename T>

void f(T);

};

The declaration for X<int>::f is a (non-templated) FunctionDecl whose parent is the class template specialization X<int>. For this declaration, getInstantiatedFromFunction() will return the FunctionDecl X<T>::A. When a complete definition of X<int>::A is required, it will be instantiated from the declaration returned by getInstantiatedFromMemberFunction().

Parameters: CheckForPendingFriendDefinition If true, also check for friend declarations that were instantiated from function definitions. Such a declaration behaves as if it is a definition for the purpose of redefinition checking, but isn't actually a "real" definition until its body is instantiated.

◆ isDeleted() bool clang::FunctionDecl::isDeleted ( ) const inline

Whether this function has been deleted.

A function that is "deleted" (via the C++0x "= delete" syntax) acts like a normal function, except that it cannot actually be called or have its address taken. Deleted functions are typically used in C++ overload resolution to attract arguments whose type or lvalue/rvalue-ness would permit the use of a different overload that would behave incorrectly. For example, one might use deleted functions to ban implicit conversion from a floating-point number to an Integer type:

◆ isInlineDefinitionExternallyVisible() bool FunctionDecl::isInlineDefinitionExternallyVisible ( ) const

For an inline function definition in C, or for a gnu_inline function in C++, determine whether the definition will be externally visible.

Inline function definitions are always available for inlining optimizations. However, depending on the language dialect, declaration specifiers, and attributes, the definition of an inline function may or may not be "externally" visible to other translation units in the program.

In C99, inline definitions are not externally visible by default. However, if even one of the global-scope declarations is marked "extern inline", the inline definition becomes externally visible (C99 6.7.4p6).

In GNU89 mode, or if the gnu_inline attribute is attached to the function definition, we use the GNU semantics for inline, which are nearly the opposite of C99 semantics. In particular, "inline" by itself will create an externally visible symbol, but "extern inline" will not create an externally visible symbol.

◆ isReservedGlobalPlacementOperator() bool FunctionDecl::isReservedGlobalPlacementOperator ( ) const

Determines whether this operator new or delete is one of the reserved global placement operators: void *operator new(size_t, void *); void *operator new[](size_t, void *); void operator delete(void *, void *); void operator delete[](void *, void *); These functions have special behavior under [new.delete.placement]: These functions are reserved, a C++ program may not define functions that displace the versions in the Standard C++ library.

The provisions of [basic.stc.dynamic] do not apply to these reserved placement forms of operator new and operator delete.

This function must be an allocation or deallocation function.

◆ isTemplateInstantiation() bool FunctionDecl::isTemplateInstantiation ( ) const ◆ isThisDeclarationADefinition() bool clang::FunctionDecl::isThisDeclarationADefinition ( ) const inline

Returns whether this specific declaration of the function is also a definition that does not contain uninstantiated body.

This does not determine whether the function has been defined (e.g., in a previous definition); for that information, use isDefined.

Note: the function declaration does not become a definition until the parser reaches the definition, if called before, this function will return false.

Whether this function is "trivial" in some specialized C++ senses.

Can only be true for default constructors, copy constructors, copy assignment operators, and destructors. Not meaningful until the class has been fully built by Sema.

TemplateArgs the template arguments that produced this function template specialization from the template. InsertPos If non-NULL, the position in the function template specialization set where the function template specialization data will be inserted. TSK the kind of template specialization this is. TemplateArgsAsWritten location info of template arguments. PointOfInstantiation point at which the function template specialization was first instantiated.
