Interface INameEnvironment

All Known Implementing Classes:

FileSystem

public interface INameEnvironment

The name environment provides a callback API that the compiler can use to look up types, compilation units, and packages in the current environment. The name environment is passed to the compiler on creation.

Methods

Modifier and Type	Method and Description
void	cleanup() This method cleans the environment.
NameEnvironmentAnswer	findType(char[][] compoundTypeName) Find a type with the given compound name.

boolean	isPackage(char[][] parentPackageName, char[] packageName) Answer whether packageName is the name of a known subpackage inside the package parentPackageName.

Method Detail

findType

NameEnvironmentAnswer findType(char[][] compoundTypeName)

Find a type with the given compound name. Answer the binary form of the type if it is known to be consistent. Otherwise, answer the compilation unit which defines the type or null if the type does not exist. Types in the default package are specified as {{typeName}}. It is unknown whether the package containing the type actually exists. NOTE: This method can be used to find a member type using its internal name A$B, but the source file for A is answered if the binary file is inconsistent.

findType

NameEnvironmentAnswer findType(char[] typeName,
                             char[][] packageName)

Find a type named in the package . Answer the binary form of the type if it is known to be consistent. Otherwise, answer the compilation unit which defines the type or null if the type does not exist. The default package is indicated by char[0][]. It is known that the package containing the type exists. NOTE: This method can be used to find a member type using its internal name A$B, but the source file for A is answered if the binary file is inconsistent.

isPackage

boolean isPackage(char[][] parentPackageName,
                char[] packageName)

Answer whether packageName is the name of a known subpackage inside the package parentPackageName. A top level package is found relative to null. The default package is always assumed to exist. For example: isPackage({{java}, {awt}}, {event}); isPackage(null, {java});

cleanup

void cleanup()

This method cleans the environment. It is responsible for releasing the memory and freeing resources. Passed that point, the name environment is no longer usable. A name environment can have a long life cycle, therefore it is the responsibility of the code which created it to decide when it is a good time to clean it up.
