38/// Manages and observes all Clang AST node importing in LLDB.
39///
40/// The ClangASTImporter takes care of two things:
41///
42/// 1. Keeps track of all ASTImporter instances in LLDB.
43///
44/// Clang's ASTImporter takes care of importing types from one ASTContext to
45/// another. This class expands this concept by allowing copying from several
46/// ASTContext instances to several other ASTContext instances. Instead of
47/// constructing a new ASTImporter manually to copy over a type/decl, this class
48/// can be asked to do this. It will construct a ASTImporter for the caller (and
49/// will cache the ASTImporter instance for later use) and then perform the
50/// import.
51///
52/// This mainly prevents that a caller might construct several ASTImporter
53/// instances for the same source/target ASTContext combination. As the
54/// ASTImporter has an internal state that keeps track of already imported
55/// declarations and so on, using only one ASTImporter instance is more
56/// efficient and less error-prone than using multiple.
57///
58/// 2. Keeps track of from where declarations were imported (origin-tracking).
59/// The ASTImporter instances in this class usually only performa a minimal
60/// import, i.e., only a shallow copy is made that is filled out on demand
61/// when more information is requested later on. This requires record-keeping
62/// of where any shallow clone originally came from so that the right original
63/// declaration can be found and used as the source of any missing information.
