57/** \defgroup CINDEX libclang: C Interface to Clang
58 *
59 * The C Interface to Clang provides a relatively small API that exposes
60 * facilities for parsing source code into an abstract syntax tree (AST),
61 * loading already-parsed ASTs, traversing the AST, associating
62 * physical source locations with elements within the AST, and other
63 * facilities that support Clang-based development tools.
64 *
65 * This C interface to Clang will never provide all of the information
66 * representation stored in Clang's C++ AST, nor should it: the intent is to
67 * maintain an API that is relatively stable from one release to the next,
68 * providing only the basic functionality needed to support development tools.
69 *
70 * To avoid namespace pollution, data types are prefixed with "CX" and
71 * functions are prefixed with "clang_".

239 * header that was used by the translation unit. If zero, all declarations
240 * will be enumerated.
241 *

247 *

250 * TU = clang_createTranslationUnit(Idx, "IndexTest.pch");
251 *
252 * // This will load all the symbols from 'IndexTest.pch'
253 * clang_visitChildren(clang_getTranslationUnitCursor(TU),
254 * TranslationUnitVisitor, 0);
255 * clang_disposeTranslationUnit(TU);

257 * // This will load all the symbols from 'IndexTest.c', excluding symbols

263 * TranslationUnitVisitor, 0);

265 * \endcode

267 * This process of creating the 'pch', loading it separately, and using it (via

269 * (which gives the indexer the same performance benefit as the compiler).

2687 * In both Objective-C and C++, a method (aka virtual member function,

2689 * Objective-C, a method is said to override any method in the class's

2692 * If no such method exists, the search continues to the class's superclass,
2693 * its protocols, and its categories, and so on. A method from an Objective-C
2694 * implementation is considered to override the same methods as its
2695 * corresponding method in the interface.
2696 *
2697 * For C++, a virtual member function overrides any virtual member
2698 * function with the same signature that occurs in its base
2699 * classes. With multiple inheritance, a virtual member function can
2700 * override several virtual member functions coming from different
2701 * base classes.
2702 *
2703 * In all cases, this function determines the immediate overridden
2704 * method, rather than all of the overridden methods. For example, if
2705 * a method is originally declared in a class A, then overridden in B
2706 * (which in inherits from A) and also in C (which inherited from B),
2707 * then the only overridden method returned from this function when
2708 * invoked on C's method will be B's method. The client may then

5481 * Perform code completion at a given location in a translation unit.
5482 *
5483 * This function performs code completion at a particular file, line, and
5484 * column within source code, providing results that suggest potential
5485 * code snippets based on the context of the completion. The basic model
5486 * for code completion is that Clang will parse a complete source file,
5487 * performing syntax checking up to the location where code-completion has
5488 * been requested. At that point, a special code-completion token is passed
5489 * to the parser, which recognizes this token and determines, based on the
5490 * current location in the C/Objective-C/C++ grammar and the state of
5491 * semantic analysis, what completions to provide. These completions are
5492 * returned via a new \c CXCodeCompleteResults structure.
5493 *
5494 * Code completion itself is meant to be triggered by the client when the
5495 * user types punctuation characters or whitespace, at which point the
5496 * code-completion location will coincide with the cursor. For example, if \c p
5497 * is a pointer, code-completion might be triggered after the "-" and then
5498 * after the ">" in \c p->. When the code-completion location is after the ">",
5499 * the completion results will provide, e.g., the members of the struct that
5500 * "p" points to. The client is responsible for placing the cursor at the
5501 * beginning of the token currently being typed, then filtering the results
5502 * based on the contents of the token. For example, when code-completing for
5503 * the expression \c p->get, the client should provide the location just after
5504 * the ">" (e.g., pointing at the "g") to this code-completion hook. Then, the
5505 * client can filter the results based on the current token text ("get"), only
5506 * showing those results that start with "get". The intent of this interface
5507 * is to separate the relatively high-latency acquisition of code-completion
5508 * results from the filtering of results on a per-character basis, which must
5509 * have a lower latency.

5512 * occur. The source files for this translation unit need not be
5513 * completely up-to-date (and the contents of those source files may
5514 * be overridden via \p unsaved_files). Cursors referring into the
5515 * translation unit may be invalidated by this invocation.
5516 *
5517 * \param complete_filename The name of the source file where code
5518 * completion should be performed. This filename may be any file
5519 * included in the translation unit.

5521 * \param complete_line The line at which code-completion should occur.
5522 *
5523 * \param complete_column The column at which code-completion should occur.

5525 * initiated code completion, and not in the middle of a lexical token.
5526 *
5527 * \param unsaved_files the Files that have not yet been saved to disk
5528 * but may be required for parsing or code completion, including the
5529 * contents of those files. The contents and name of these files (as
5530 * specified by CXUnsavedFile) are copied when necessary, so the
5531 * client only needs to guarantee their validity until the call to
5532 * this function returns.
