Class AbstractContextExtender
java.lang.Object
org.eclipse.jet.AbstractContextExtender
Deprecated. Since 0.9.0. Use public methods
JET2Context.addPrivateData(String, Object) and
JET2Context.getPrivateData(String)
-
public abstract class AbstractContextExtender
- extends java.lang.Object
Base class for extending
JET2Context. The JET execution context,
JET2Context, is capable of
storing private data for various extensions. Subclass this class to create such a private data extension. Steps to create an context
extension.
- Subclass this class
- Implement
createExtendedData(JET2Context) to return a object representing the private data of the context extension. This method is only called the first time
an extender is constructed for a particular context.
The method
getExtendedData() returns the data to the current context instance.
- Implement additional methods that make use of this private context data.
- Create a constructor that accepts a
JET2Context and passes it to the super constructor. It is recommended that
this constructor be private.
- (Recommended) Implement a
public static YourExtender getInstance(JET2Context) method that returns an instance the
AbstractContextExtender subclass.
