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.
JavaFileObject.Kind protected final URI uri
A URI for this file object.
protected final JavaFileObject.Kind kind
The kind of this file object.
protected SimpleJavaFileObject(URI uri,
JavaFileObject.Kind kind) Construct a SimpleJavaFileObject of the given kind and with the given URI.
uri - the URI for this file objectkind - the kind of this file objectpublic URI toUri()
Description copied from interface: FileObject
Returns a URI identifying this file object.
toUri in interface FileObject
public String getName()
Description copied from interface: FileObject
Gets a user-friendly name for this file object. The exact value returned is not specified but implementations should take care to preserve names as given by the user. For example, if the user writes the filename "BobsApp\Test.java" on the command line, this method should return "BobsApp\Test.java" whereas the toUri method might return file:///C:/Documents%20and%20Settings/UncleBob/BobsApp/Test.java.

public InputStream openInputStream()
throws IOException This implementation always throws UnsupportedOperationException. Subclasses can change this behavior as long as the contract of FileObject is obeyed.

throws IOException This implementation always throws UnsupportedOperationException. Subclasses can change this behavior as long as the contract of FileObject is obeyed.
openOutputStream in interface FileObject
IOException - if an I/O error occurredpublic Reader openReader(boolean ignoreEncodingErrors)
throws IOException Wraps the result of getCharContent(boolean) in a Reader. Subclasses can change this behavior as long as the contract of FileObject is obeyed.

This implementation returns 0L. Subclasses can change this behavior as long as the contract of FileObject is obeyed.

This implementation does nothing. Subclasses can change this behavior as long as the contract of FileObject is obeyed.

falsepublic JavaFileObject.Kind getKind()
Description copied from interface: JavaFileObject
Gets the kind of this file object.
getKind in interface JavaFileObject
this.kindpublic 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 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.
isNameCompatible in interface JavaFileObject
simpleName - a simple name of a classkind - a kindtrue if this file object is compatible; false otherwisepublic NestingKind getNestingKind()
This implementation returns null. Subclasses can change this behavior as long as the contract of JavaFileObject is obeyed.
getNestingKind in interface JavaFileObject
null if the nesting kind is not knownpublic Modifier getAccessLevel()
This implementation returns null. Subclasses can change this behavior as long as the contract of JavaFileObject is obeyed.

public String toString()
Description copied from class: Object
Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.
The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
