Detailed Description

Decl - This represents one declaration (or definition), e.g.

a variable, typedef, function, struct, etc.

Note: There are objects tacked on before the beginning of Decl (and its subclasses) in its Decl::operator new(). Proper alignment of all subclasses (not requiring more than the alignment of Decl) is asserted in DeclBase.cpp.

Member Enumeration Documentation

◆ FriendObjectKind

enum clang::Decl::FriendObjectKind

FOK_None	Not a friend object.
FOK_Declared	A friend of a previously-declared entity.
FOK_Undeclared	A friend of a previously-undeclared entity.

Definition at line 1216 of file DeclBase.h.

◆ IdentifierNamespace

enum clang::Decl::IdentifierNamespace

IdentifierNamespace - The different namespaces in which declarations may appear.

According to C99 6.2.3, there are four namespaces, labels, tags, members and ordinary identifiers. C++ describes lookup completely differently: certain lookups merely "ignore" certain kinds of declarations, usually based on whether the declaration is of a type, etc.

These are meant as bitmasks, so that searches in C++ can look into the "tag" namespace during ordinary lookup.

Decl currently provides 15 bits of IDNS bits.

Enumerator
IDNS_Label	Labels, declared with 'x:' and referenced with 'goto x'.
IDNS_Tag	Tags, declared with 'struct foo;' and referenced with 'struct foo'. All tags are also types. This is what elaborated-type-specifiers look for in C. This also contains names that conflict with tags in the same scope but that are otherwise ordinary names (non-type template parameters and indirect field declarations).
IDNS_Type	Types, declared with 'struct foo', typedefs, etc. This is what elaborated-type-specifiers look for in C++, but note that it's ill-formed to find a non-tag.
IDNS_Member	Members, declared with object declarations within tag definitions. In C, these can only be found by "qualified" lookup in member expressions. In C++, they're found by normal lookup.
IDNS_Namespace	Namespaces, declared with 'namespace foo {}'. Lookup for nested-name-specifiers find these.
IDNS_Ordinary	Ordinary names. In C, everything that's not a label, tag, member, or function-local extern ends up here.
IDNS_ObjCProtocol	Objective C @protocol.
IDNS_OrdinaryFriend	This declaration is a friend function. A friend function declaration is always in this namespace but may also be in IDNS_Ordinary if it was previously declared.
IDNS_TagFriend	This declaration is a friend class. A friend class declaration is always in this namespace but may also be in IDNS_Tag\|IDNS_Type if it was previously declared.
IDNS_Using	This declaration is a using declaration. A using declaration introduces a number of other declarations into the current scope, and those declarations use the IDNS of their targets, but the actual using declarations go in this namespace.
IDNS_NonMemberOperator	This declaration is a C++ operator declared in a non-class context. All such operators are also in IDNS_Ordinary. C++ lexical operator lookup looks for these.
IDNS_LocalExtern	This declaration is a function-local extern declaration of a variable or function. This may also be IDNS_Ordinary if it has been declared outside any function. These act mostly like invisible friend declarations, but are also visible to unqualified lookup within the scope of the declaring function.
IDNS_OMPReduction	This declaration is an OpenMP user defined reduction construction.
IDNS_OMPMapper	This declaration is an OpenMP user defined mapper.

◆ Kind

enum clang::Decl::Kind

Lists the kind of concrete classes of Decl.

Definition at line 89 of file DeclBase.h.

◆ ModuleOwnershipKind

enum class clang::Decl::ModuleOwnershipKind : unsigned char

strong

The kind of ownership a declaration has, for visibility purposes.

This enumeration is designed such that higher values represent higher levels of name hiding.

Enumerator
Unowned	This declaration is not owned by a module.
Visible	This declaration has an owning module, but is globally visible (typically because its owning module is visible and we know that modules cannot later become hidden in this compilation). After serialization and deserialization, this will be converted to VisibleWhenImported.
VisibleWhenImported	This declaration has an owning module, and is visible when that module is imported.
ReachableWhenImported	This declaration has an owning module, and is visible to lookups that occurs within that module. And it is reachable in other module when the owning module is transitively imported.
ModulePrivate	This declaration has an owning module, but is only visible to lookups that occur within that module. The discarded declarations in global module fragment belongs to this group too.

Definition at line 216 of file DeclBase.h.

◆ ObjCDeclQualifier

enum clang::Decl::ObjCDeclQualifier

ObjCDeclQualifier - 'Qualifiers' written next to the return and parameter types in method declarations.

Other than remembering them and mangling them into the method's signature string, these are ignored by the compiler; they are consumed by certain remote-messaging frameworks.

in, inout, and out are mutually exclusive and apply only to method parameters. bycopy and byref are mutually exclusive and apply only to method parameters (?). oneway applies only to results. All of these expect their corresponding parameter to have a particular type. None of this is currently enforced by clang.

This should be kept in sync with ObjCDeclSpec::ObjCDeclQualifier.

Enumerator
OBJC_TQ_None
OBJC_TQ_In
OBJC_TQ_Inout
OBJC_TQ_Out
OBJC_TQ_Bycopy
OBJC_TQ_Byref
OBJC_TQ_Oneway
OBJC_TQ_CSNullability	The nullability qualifier is set when the nullability of the result or parameter was expressed via a context-sensitive keyword.

Determine the availability of the given declaration.

This routine will determine the most restrictive availability of the given declaration (e.g., preferring 'unavailable' to 'deprecated').

Parameters

Message	If non-NULL and the result is not `AR_Available`, will be set to a (possibly empty) message describing why the declaration has not been introduced, is deprecated, or is unavailable.
EnclosingVersion	The version to compare with. If empty, assume the deployment target version.
RealizedPlatform	If non-NULL and the availability result is found in an available attribute it will set to the platform which is written in the available attribute.

Allocate memory for a deserialized declaration.

This routine must be used to allocate memory for any declaration that is deserialized from a module file.

Parameters

Size	The size of the allocated object.
Ctx	The context in which we will allocate memory.
ID	The global ID of the deserialized declaration.
Extra	The amount of extra space to allocate after the object.
