CINDEX_LINKAGE enum CXLanguageKind clang_getCursorLanguage | ( | CXCursor | cursor | ) |
Determine the "language" of the entity referred to by a given cursor.
CINDEX_LINKAGE CXCursor clang_getCursorLexicalParent | ( | CXCursor | cursor | ) |
Determine the lexical parent of the given cursor.
The lexical parent of a cursor is the cursor in which the given cursor
was actually written. For many declarations, the lexical and semantic parents are equivalent (the semantic parent is returned by clang_getCursorSemanticParent()
). They diverge when declarations or definitions are provided out-of-line. For example:
In the out-of-line definition of C::f
, the semantic parent is the class C
, of which this function is a member. The lexical parent is the place where the declaration actually occurs in the source code; in this case, the definition occurs in the translation unit. In general, the lexical parent for a given entity can change without affecting the semantics of the program, and the lexical parent of different declarations of the same entity may be different. Changing the semantic parent of a declaration, on the other hand, can have a major impact on semantics, and redeclarations of a particular entity should all have the same semantic context.
In the example above, both declarations of C::f
have C
as their semantic context, while the lexical context of the first C::f
is C
and the lexical context of the second C::f
is the translation unit.
For declarations written in the global scope, the lexical parent is the translation unit.

CXString * | unavailable_message, | ||
CXPlatformAvailability * | availability, | ||
int | availability_size | ||
) |
Determine the availability of the entity that this cursor refers to on any platforms for which availability information is known.
cursor | The cursor to query. |
always_deprecated | If non-NULL, will be set to indicate whether the entity is deprecated on all platforms. |
deprecated_message | If non-NULL, will be set to the message text provided along with the unconditional deprecation of this entity. The client is responsible for deallocating this string. |
always_unavailable | If non-NULL, will be set to indicate whether the entity is unavailable on all platforms. |
unavailable_message | If non-NULL, will be set to the message text provided along with the unconditional unavailability of this entity. The client is responsible for deallocating this string. |

availability_size | The number of elements available in the availability array. |
availability_size
).Note that the client is responsible for calling clang_disposeCXPlatformAvailability
to free each of the platform-availability structures returned. There are min(N, availability_size)
such structures.
CINDEX_LINKAGE CXCursor clang_getCursorSemanticParent | ( | CXCursor | cursor | ) |
Determine the semantic parent of the given cursor.
The semantic parent of a cursor is the cursor that semantically contains the given cursor
. For many declarations, the lexical and semantic parents are equivalent (the lexical parent is returned by clang_getCursorLexicalParent()
). They diverge when declarations or definitions are provided out-of-line. For example:
In the out-of-line definition of C::f
, the semantic parent is the class C
, of which this function is a member. The lexical parent is the place where the declaration actually occurs in the source code; in this case, the definition occurs in the translation unit. In general, the lexical parent for a given entity can change without affecting the semantics of the program, and the lexical parent of different declarations of the same entity may be different. Changing the semantic parent of a declaration, on the other hand, can have a major impact on semantics, and redeclarations of a particular entity should all have the same semantic context.
In the example above, both declarations of C::f
have C
as their semantic context, while the lexical context of the first C::f
is C
and the lexical context of the second C::f
is the translation unit.
For global declarations, the semantic parent is the translation unit.

CINDEX_LINKAGE enum CXVisibilityKind clang_getCursorVisibility | ( | CXCursor | cursor | ) |

cursor | The cursor to query. |
CINDEX_LINKAGE CXFile clang_getIncludedFile | ( | CXCursor | cursor | ) |
Retrieve the file that is included by the given inclusion directive cursor.
CINDEX_LINKAGE CXCursor clang_getNullCursor | ( | void | ) |
Retrieve the NULL cursor, which represents no entity.
CINDEX_LINKAGE void clang_getOverriddenCursors | ( | CXCursor | cursor, |
CXCursor ** | overridden, | ||
unsigned * | num_overridden | ||
) |
Determine the set of methods that are overridden by the given method.
In both Objective-C and C++, a method (aka virtual member function, in C++) can override a virtual method in a base class. For Objective-C, a method is said to override any method in the class's base class, its protocols, or its categories' protocols, that has the same selector and is of the same kind (class or instance). If no such method exists, the search continues to the class's superclass, its protocols, and its categories, and so on. A method from an Objective-C implementation is considered to override the same methods as its corresponding method in the interface.
For C++, a virtual member function overrides any virtual member function with the same signature that occurs in its base classes. With multiple inheritance, a virtual member function can override several virtual member functions coming from different base classes.
In all cases, this function determines the immediate overridden method, rather than all of the overridden methods. For example, if a method is originally declared in a class A, then overridden in B (which in inherits from A) and also in C (which inherited from B), then the only overridden method returned from this function when invoked on C's method will be B's method. The client may then invoke this function again, given the previously-found overridden methods, to map out the complete method-override set.
cursor | A cursor representing an Objective-C or C++ method. This routine will compute the set of methods that this method overrides. |
overridden | A pointer whose pointee will be replaced with a pointer to an array of cursors, representing the set of overridden methods. If there are no overridden methods, the pointee will be set to NULL. The pointee must be freed via a call to clang_disposeOverriddenCursors() . |
num_overridden | A pointer to the number of overridden functions, will be set to the number of overridden functions in the array pointed to by overridden . |
