public abstract class FinderViewImpl
extends ViewObjectImpl

Abstract base class for Finder-Based View Object. This class extends ViewObjectImpl. Beyond the base ViewObjectImpl functionality, this class is responsible for interacting with the Local Entity Bean Home to execute the designated Local Entity Bean finder and managing the result collection.

When the user builds an EJB Finder View Object for a Local Entity Bean, a subclass of this class is generated.

Method Detail

applyViewCriteria

public void applyViewCriteria(ViewCriteria criteria)
Overrides the base implementation of applyViewCriteria(oracle.jbo.ViewCriteria).

It call ViewCriteria.setCriteriaForQuery(boolean) to mark the View Criteria to be used for in memory row filtering. Then, it calls the base implementation.

Returns:
the Entity Bean Home reference.

setEJBLocalHome

protected abstract void setEJBLocalHome(javax.ejb.EJBLocalHome ejbHome)
An abstract method which stores the Entity Bean Home reference.

A subclass of this class has an implementation of this method which assigns ejbHome to a field of that subclass.

Parameters:

An abstract method that calls the designated Local Entity Bean finder.

A subclass of this class has an implementation of this method which calls the specific finder. Values of params are passed to the finder as parameters.

Parameters:
qc - the Query Collection.
params - parameter values to be used when calling the finder.
noUserParams - indicates how many of the parameter values in params is user specified parameters.
Returns:
the collection returned by the finder.

hasNextForCollection

protected boolean hasNextForCollection(java.lang.Object qc)
Overrides the base implementation of hasNextForCollection(Object). Determines whether the Query Collection has next row or not from the Entity Bean collection returned from the previous call to the finder.

Overrides:
hasNextForCollection in class ViewObjectImpl
Parameters:
qc - the Query Collection.
Returns:
true if the collection has more rows. false otherwise.

createRowFromResultSet

protected ViewRowImpl createRowFromResultSet(java.lang.Object qc,
                                             java.sql.ResultSet resultSet)
Overrides the base implementation of createRowFromResultSet(Object, java.sql.ResultSet). Creates a View Row from the next Entity Bean and returns it.
