StandardJavaFileManager

All Superinterfaces:

AutoCloseable, Closeable, Flushable, JavaFileManager, OptionChecker
```
public interface StandardJavaFileManager
extends JavaFileManager
```
File manager based on java.io.File. A common way to obtain an instance of this class is using getStandardFileManager, for example:
```
   JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
    DiagnosticCollector<JavaFileObject> diagnostics =
       new  DiagnosticCollector<JavaFileObject>();
   StandardJavaFileManager fm = compiler.getStandardFileManager(diagnostics, null, null);
 
```
This file manager creates file objects representing regular files, zip file entries, or entries in similar file system based containers. Any file object returned from a file manager implementing this interface must observe the following behavior:
- File names need not be canonical.
- For file objects representing regular files
  - the method FileObject.delete() is equivalent to File.delete(),
  - the method FileObject.getLastModified() is equivalent to File.lastModified(),
  - the methods FileObject.getCharContent(boolean), FileObject.openInputStream(), and FileObject.openReader(boolean) must succeed if the following would succeed (ignoring encoding issues):
    new FileInputStream(new File(fileObject.toUri()))
  - and the methods FileObject.openOutputStream(), and FileObject.openWriter() must succeed if the following would succeed (ignoring encoding issues):
    new FileOutputStream(new File(fileObject.toUri()))
- The URI returned from FileObject.toUri()
  - must be absolute (have a schema), and
  - must have a normalized path component which can be resolved without any process-specific context such as the current directory (file names must be absolute).
According to these rules, the following URIs, for example, are allowed:
- file:///C:/Documents%20and%20Settings/UncleBob/BobsApp/Test.java
- jar:///C:/Documents%20and%20Settings/UncleBob/lib/vendorA.jar!com/vendora/LibraryClass.class
Whereas these are not (reason in parentheses):
- file:BobsApp/Test.java (the file name is relative and depend on the current directory)
- jar:lib/vendorA.jar!com/vendora/LibraryClass.class (the first half of the path depends on the current directory, whereas the component after ! is legal)
- Test.java (this URI depends on the current directory and does not have a schema)
- jar:///C:/Documents%20and%20Settings/UncleBob/BobsApp/../lib/vendorA.jar!com/vendora/LibraryClass.class (the path is not normalized)

  - isSameFile
```
boolean isSameFile(FileObject a,
                   FileObject b)
```
    Compares two file objects and return true if they represent the same canonical file, zip file entry, or entry in any file system based container.
    
    Specified by:
    
    isSameFile in interface JavaFileManager
    
    Parameters:
    
    a - a file object
    
    b - a file object
    
    Returns:
    
    true if the given file objects represent the same canonical file or zip file entry; false otherwise
    
    Throws:
    
    IllegalArgumentException - if either of the arguments were created with another file manager implementation
  - getJavaFileObjectsFromFiles
```
Iterable<? extends JavaFileObject> getJavaFileObjectsFromFiles(Iterable<? extends File> files)
```
    Gets file objects representing the given files.
    
    Parameters:
    
    files - a list of files
    
    Returns:
    
    a list of file objects
    
    Throws:
    
    IllegalArgumentException - if the list of files includes a directory
  - getJavaFileObjects
```
Iterable<? extends JavaFileObject> getJavaFileObjects(File... files)
```
    Gets file objects representing the given files. Convenience method equivalent to:
```
     getJavaFileObjectsFromFiles(Arrays.asList(files))
 
```
    Parameters:
    
    files - an array of files
    
    Returns:
    
    a list of file objects
    
    Throws:
    
    IllegalArgumentException - if the array of files includes a directory
    
    NullPointerException - if the given array contains null elements
  - getJavaFileObjectsFromStrings
```
Iterable<? extends JavaFileObject> getJavaFileObjectsFromStrings(Iterable<String> names)
```
    Gets file objects representing the given file names.
    
    Parameters:
    
    names - a list of file names
    
    Returns:
    
    a list of file objects
    
    Throws:
    
    IllegalArgumentException - if the list of file names includes a directory
  - getJavaFileObjects
```
Iterable<? extends JavaFileObject> getJavaFileObjects(String... names)
```
    Gets file objects representing the given file names. Convenience method equivalent to:
```
     getJavaFileObjectsFromStrings(Arrays.asList(names))
 
```
    Parameters:
    
    names - a list of file names
    
    Returns:
    
    a list of file objects
    
    Throws:
    
    IllegalArgumentException - if the array of file names includes a directory
    
    NullPointerException - if the given array contains null elements
  - setLocation
```
void setLocation(JavaFileManager.Location location,
                 Iterable<? extends File> path)
          throws IOException
```
    Associates the given path with the given location. Any previous value will be discarded.
    
    Parameters:
    
    location - a location
    
    path - a list of files, if null use the default path for this location
    
    Throws:
    
    IllegalArgumentException - if location is an output location and path does not contain exactly one element
    
    IOException - if location is an output location and path does not represent an existing directory
