All Implemented Interfaces:

FileObject, JavaFileObject
```
public class SimpleJavaFileObject
extends Object
implements JavaFileObject
```
Provides simple implementations for most methods in JavaFileObject. This class is designed to be subclassed and used as a basis for JavaFileObject implementations. Subclasses can override the implementation and specification of any method of this class as long as the general contract of JavaFileObject is obeyed.

    Returns:
    
    a Reader wrapping the result of getCharContent
    
    Throws:
    
    IllegalStateException - if this file object was opened for writing and does not support reading
    
    UnsupportedOperationException - if this kind of file object does not support character access
    
    IOException - if an I/O error occurred
  - getCharContent
```
public CharSequence getCharContent(boolean ignoreEncodingErrors)
                            throws IOException

    This implementation always throws UnsupportedOperationException. Subclasses can change this behavior as long as the contract of FileObject is obeyed.
    
    Specified by:
    
    getCharContent in interface FileObject
    
    Parameters:
    
    ignoreEncodingErrors - ignore encoding errors if true
    
    Returns:

    Returns:
    
    false
  - getKind
```
public JavaFileObject.Kind getKind()
```
    Description copied from interface: JavaFileObject
    
    Returns the kind of this file object.
    
    Specified by:
    
    getKind in interface JavaFileObject
    
    Returns:
    
    this.kind
  - isNameCompatible
```
public boolean isNameCompatible(String simpleName,
                                JavaFileObject.Kind kind)
```
    This implementation compares the path of its URI to the given simple name. This method returns true if the given kind is equal to the kind of this object, and if the path is equal to simpleName + kind.extension or if it ends with "/" + simpleName + kind.extension.
    This method calls getKind() and FileObject.toUri() and does not access the fields uri and kind directly.
    
    Subclasses can change this behavior as long as the contract of JavaFileObject is obeyed.
    
    Specified by:
    
    isNameCompatible in interface JavaFileObject
    
    Parameters:
    
    simpleName - a simple name of a class
    
    kind - a kind
    
    Returns:
    
    true if this file object is compatible; false otherwise
  - getNestingKind
```
public NestingKind getNestingKind()
```
    This implementation returns null. Subclasses can change this behavior as long as the contract of JavaFileObject is obeyed.
    
    Specified by:
    
    getNestingKind in interface JavaFileObject
    
    Returns:
    
    the nesting kind, or null if the nesting kind is not known
  - getAccessLevel
```
public Modifier getAccessLevel()
```
    This implementation returns null. Subclasses can change this behavior as long as the contract of JavaFileObject is obeyed.
    
    Specified by:
    
    getAccessLevel in interface JavaFileObject
    
    Returns:
    
    the access level
