  Returns:

  a file object, might return null if the file does not exist

  Throws:

  IllegalArgumentException - if the location is not known to this file manager and the file manager does not support unknown locations, or if the kind is not valid

• getJavaFileForOutput

  public JavaFileObject getJavaFileForOutput(JavaFileManager.Location location,
                                             String className,
                                             JavaFileObject.Kind kind,
                                             FileObject sibling)
                                      throws IOException

  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.

  Specified by:

  getJavaFileForOutput in interface  JavaFileManager

  Parameters:

  location - a location

  className - the name of a class

  kind - the kind of file, must be one of SOURCE or CLASS

  sibling - a file object to be used as hint for placement; might be null

  Returns:

  a file object for output

  Throws:

  IllegalArgumentException - if sibling is not known to this file manager, or if the location is not known to this file manager and the file manager does not support unknown locations, or if the kind is not valid

  IllegalStateException - JavaFileManager.close() has been called and this file manager cannot be reopened

  IOException - if an I/O error occurred, or if JavaFileManager.close() has been called and this file manager cannot be reopened

• getFileForInput

  public FileObject getFileForInput(JavaFileManager.Location location,
                                    String packageName,
                                    String relativeName)
                             throws IOException

  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".

  Specified by:

  getFileForInput in interface  JavaFileManager

  Parameters:

  location - a location

  packageName - a package name

  relativeName - a relative name

  Returns:

  a file object, might return null if the file does not exist

  Throws:

  IllegalArgumentException - if the location is not known to this file manager and the file manager does not support unknown locations, or if relativeName is not valid

  IllegalStateException - if JavaFileManager.close() has been called and this file manager cannot be reopened

  IOException - if an I/O error occurred, or if JavaFileManager.close() has been called and this file manager cannot be reopened

• getFileForOutput

  public FileObject getFileForOutput(JavaFileManager.Location location,
                                     String packageName,
                                     String relativeName,
                                     FileObject sibling)
                              throws IOException

  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. To facilitate this behavior, javac might provide the originating source file as sibling when calling this method.

  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.

  Specified by:

  getFileForOutput in interface  JavaFileManager

  Parameters:

  location - a location

  packageName - a package name

  relativeName - a relative name

  sibling - a file object to be used as hint for placement; might be null

  Returns:

  a file object

  Throws:

  IllegalArgumentException - if sibling is not known to this file manager, or if the location is not known to this file manager and the file manager does not support unknown locations, or if relativeName is not valid

  IllegalStateException - if JavaFileManager.close() has been called and this file manager cannot be reopened

  IOException - if an I/O error occurred, or if JavaFileManager.close() has been called and this file manager cannot be reopened

• flush

  public void flush()
             throws IOException

  Description copied from interface: JavaFileManager

  IOException - if an I/O error occurred

  See Also:

  JavaFileManager.close()

• close

  public void close()
             throws IOException

  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.

  Specified by:

  close in interface  Closeable

  Specified by:

  close in interface  AutoCloseable

  Specified by:

  close in interface  JavaFileManager

  Throws:

  IOException - if an I/O error occurred
