M
- the kind of file manager forwarded to by this objectpublic class ForwardingJavaFileManager<M extends JavaFileManager> extends Object implements JavaFileManager
Forwards calls to a given file manager. Subclasses of this class might override some of these methods and might also provide additional fields and methods.
JavaFileManager.Location
protected final M extends JavaFileManager fileManager
The file manager which all methods are delegated to.
protected ForwardingJavaFileManager(M fileManager)
Creates a new instance of ForwardingJavaFileManager.
fileManager
- delegate to this file managerpublic ClassLoader getClassLoader(JavaFileManager.Location location)
Description copied from interface: JavaFileManager
Gets a class loader for loading plug-ins from the given location. For example, to load annotation processors, a compiler will request a class loader for the ANNOTATION_PROCESSOR_PATH
location.

Description copied from interface: JavaFileManager
Lists all file objects matching the given criteria in the given location. List file objects in "subpackages" if recurse is true.
Note: even if the given location is unknown to this file manager, it may not return null
. Also, an unknown location may not cause an exception.

and return true, otherwise return false.

Description copied from interface: JavaFileManager
Gets a file object for output representing the specified class of the specified kind in the given location.
Optionally, this file manager might consider the sibling as a hint for where to place the output. The exact semantics of this hint is unspecified. The JDK compiler, javac, for example, will place class files in the same directories as originating source files unless a class file output directory is provided. To facilitate this behavior, javac might provide the originating source file as sibling when calling this method.

Description copied from interface: JavaFileManager
Gets a file object for input representing the specified relative name in the specified package in the given location.
If the returned object represents a source or class file, it must be an instance of JavaFileObject
.
Informally, the file object returned by this method is located in the concatenation of the location, package name, and relative name. For example, to locate the properties file "resources/compiler.properties" in the package "com.sun.tools.javac" in the SOURCE_PATH location, this method might be called like so:
getFileForInput(SOURCE_PATH, "com.sun.tools.javac", "resources/compiler.properties");
If the call was executed on Windows, with SOURCE_PATH set to "C:\Documents and Settings\UncleBob\src\share\classes"
, a valid result would be a file object representing the file "C:\Documents and Settings\UncleBob\src\share\classes\com\sun\tools\javac\resources\compiler.properties"
.

Description copied from interface: JavaFileManager
Gets a file object for output representing the specified relative name in the specified package in the given location.
Optionally, this file manager might consider the sibling as a hint for where to place the output. The exact semantics of this hint is unspecified. The JDK compiler, javac, for example, will place class files in the same directories as originating source files unless a class file output directory is provided.

If the returned object represents a source or class file, it must be an instance of JavaFileObject

Informally, the file object returned by this method is located in the concatenation of the location, package name, and relative name or next to the sibling argument. See getFileForInput
for an example.

Description copied from interface: JavaFileManager
Releases any resources opened by this file manager directly or indirectly. This might render this file manager useless and the effect of subsequent calls to methods on this object or any objects obtained through this object is undefined unless explicitly allowed. However, closing a file manager which has already been closed has no effect.
