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.

JavaClassNode

Method Detail

createReader

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

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()
