All Known Implementing Classes:

ExtentImpl

public interface KodoExtent

extends Extent

Extension of the Extent interface that adds some Kodo-specific methods.

Method Summary

Class[]	getImplementingClasses() Returns an array of top-level implementing classes.
Class[]	getImplementingClasses(boolean withMetadata) Returns an array of top-level implementing classes.
List	list() Returns a list of all objects represented by this extent.

Method Detail

list

public List list()

Returns a list of all objects represented by this extent.
This method creates a List by traversing the entire iterator returned by a call to Extent.iterator(). This means that Collection.size() will work correctly, but if the extent represents a large data set, this method may be quite slow and may consume quite a bit of memory.

getImplementingClasses

public Class[] getImplementingClasses()

Returns an array of top-level implementing classes. If this Extent's candidate class is a concrete class, then the array will contain only that class. If it is an interface, then an array of all the top-level implementors that have been registered by the JDOImplHelper will be returned.

getImplementingClasses

public Class[] getImplementingClasses(boolean withMetadata)

Returns an array of top-level implementing classes. If this Extent's candidate class is a concrete class, then the array will contain only that class. If it is an interface, then an array of all the top-level implementors that have been registered by the JDOImplHelper will be returned.

Parameters:

withMetadata - if true, exclude those implementors that do no have metadata.
