14 * The name environment provides a callback API that the compiler can use to
15 * look up types, compilation units, and packages in the current environment.
16 * The name environment is passed to the compiler on creation.
18 public interface INameEnvironment {
20 * Find a type with the given compound name. Answer the binary form of the
21 * type if it is known to be consistent. Otherwise, answer the compilation
22 * unit which defines the type or null if the type does not exist. Types in
23 * the default package are specified as {{typeName}}.
25 * It is unknown whether the package containing the type actually exists.
27 * NOTE: This method can be used to find a member type using its internal
28 * name A$B, but the source file for A is answered if the binary file is
32 NameEnvironmentAnswer findType(char[][] compoundTypeName);
35 * Find a type named <typeName> in the package <packageName>. Answer the
36 * binary form of the type if it is known to be consistent. Otherwise,
37 * answer the compilation unit which defines the type or null if the type
38 * does not exist. The default package is indicated by char[0][].
40 * It is known that the package containing the type exists.
42 * NOTE: This method can be used to find a member type using its internal
43 * name A$B, but the source file for A is answered if the binary file is
47 NameEnvironmentAnswer findType(char[] typeName, char[][] packageName);
50 * Answer whether packageName is the name of a known subpackage inside the
51 * package parentPackageName. A top level package is found relative to null.
52 * The default package is always assumed to exist.
54 * For example: isPackage({{java}, {awt}}, {event}); isPackage(null,
58 boolean isPackage(char[][] parentPackageName, char[] packageName);
61 * This method cleans the environment uo. It is responsible for releasing
62 * the memory and freeing resources. Passed that point, the name environment
63 * is no longer usable.
65 * A name environment can have a long life cycle, therefore it is the
66 * responsibility of the code which created it to decide when it is a good
67 * time to clean it up.
