public class CompositeObjectMap<E extends DataObject<E> & UniqueidentifiedInterface<E>,F extends DataObject<F> & UniqueidentifiedInterface<F>>
extends java.lang.Object

A composite object map allows to order objects by a parent object id and a number of classifiers, the classifiers being typically the value of some fields of the object. This is used in the Smart Report, and is also available for other actions, typically the ones for action

CompositeObjectMap

@SafeVarargs
public CompositeObjectMap(java.util.function.Function<F,DataObjectId<E>> parentidextractor,
                                        java.util.function.Function<F,java.lang.String>... classifier)

Parameters:

parentidextractor - a function that gets the parent id from the object (expected to require no call to persistence layer)

classifier - a function to extract the value for each of the classifiers (expected to require no call to persistence layer)

Method Detail

classifyObjects

public void classifyObjects(F[] objects)

Parameters:

objects - the list of objects to classify. It is expected to be non null, though some of the classifier values may be null.

classifyObject

public void classifyObject(F object)

Parameters:

object - the object to classify. It is expected to be non null, though some of the classifier values may be null.

getObjectsForRootParentId

public java.util.List<F> getObjectsForRootParentId(DataObjectId<E> parentid)

gets all the objects for the given parent data object id

Parameters:

parentid - id of the parent object

Returns:

the list of children objects for this parent

getObjectsForValue

public java.util.List<F> getObjectsForValue(DataObjectId<E> parentid,
                                            java.lang.String[] classifier)

Parameters:

parentid - parent id. This may be null

classifier: - it should have the number of values of the map, some values may be null

Returns:

a list if something exists, null else
