All Implemented Interfaces:

Displayable, Element, LazyLoadable, Locatable, Subject, Dirtyable

public final class JavaClassNode

extends JavaNode

The JavaNode interface represents a Java class element in the JDeveloper browser. A JavaNode could be either a .class file or a .java file; however, JDeveloper normally represents a .java file with the JavaSourceNode, which extends JavaNode.

In addition to providing the usual Node features, a JavaNode provides access to both a code-level view (through the JOT subsystem) and a component view (through the CMT subsystem) of the Java class.

Method Detail

createReader

protected java.io.Reader createReader(java.net.URL url)
                               throws java.io.IOException

Description copied from class: TextNode

Fetch a Reader for reading the contents of this node from the given URL. Subclasses may override this if they have special requirements for creating the Reader.

Overrides:

createReader in class TextNode

Parameters:

url - the URL to fetch a Reader for

Returns:

a Reader for loading the contents of this node from storage

Throws:

java.io.IOException

saveImpl

protected void saveImpl()

Description copied from class: Node

Subclasses should override this method to customize the save() behavior. Node.save() invokes this only if the node is dirty, under write lock. The Node implementation does nothing.

Overrides:

saveImpl in class TextNode

isReadOnly

public boolean isReadOnly()

Description copied from class: TextNode

Returns true if the Node is read-only.

TextNode overrides to force the underlying buffer to be read only.

Overrides:

isReadOnly in class TextNode

See Also:

Node.isReadOnly()

emitFile

protected static java.lang.String emitFile(JavaFile javaFile)

Given a JavaFile, emit a source stub for that JavaFile

Parameters:

javaFile - A JavaFile which cannot be null

Returns:

A source stub for the JavaFile
