54 /// CompilerInstance - Helper class for managing a single instance of the Clang
57 /// The CompilerInstance serves two purposes:
58 /// (1) It manages the various objects which are necessary to run the compiler,
59 /// for example the preprocessor, the target information, and the AST
61 /// (2) It provides utility routines for constructing and manipulating the
62 /// common Clang objects.
64 /// The compiler instance generally owns the instance of all the objects that it
65 /// manages. However, clients can still share objects by manually setting the
66 /// object and retaking ownership prior to destroying the CompilerInstance.
68 /// The compiler instance is intended to simplify clients, but not to lock them
69 /// in to the compiler instance for everything. When possible, utility functions
70 /// come in two forms; a short form that reuses the CompilerInstance objects,
71 /// and a long form that takes explicit instances of any required objects.
