Description copied from interface: JavaFileManager
Returns a file object for input representing the specified relative name in the specified package in the given package-oriented 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
Returns a file object for input representing the specified relative name in the specified package in the given package-oriented 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 package-oriented location

packageName - a package name

relativeName - a relative name

Returns:

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

Throws:

java.lang.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, or if the location is a module-oriented location

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

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

```
Description copied from interface: JavaFileManager

Returns 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 - aan output 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:

java.lang.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, or if the location is not an output location

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

Description copied from interface: JavaFileManager
Determines whether or not a given file object is "contained in" a specified location.
For a package-oriented location, a file object is contained in the location if there exist values for packageName and relativeName such that either of the following calls would return the same file object:
```
     
getFileForInput(location, packageName, relativeName)
     getFileForOutput(location, packageName, relativeName, null)
 
```
For a module-oriented location, a file object is contained in the location if there exists a module that may be obtained by the call:
```
     
getLocationForModule(location, moduleName)
 
```
such that the file object is contained in the (package-oriented) location for that module.
Specified by:

contains in interface JavaFileManager

Parameters:

location - the location

fo - the file object

Returns:

whether or not the file is contained in the location

Throws:

java.io.IOException - if there is a problem determining the result
