Method Summary

Modifier and Type	Method and Description
E	create(E e) calls the super and AbstractEntityController.setNewEntity(org.fryske_akademy.jpa.EntityInterface) with null.
String	deleteTitle() show some usefull info to a user what is about to be deleted
boolean	disableDelete() delete should be disabled when toDelete() is null;
void	editNew(String table) Calls prepareCreate() and either executes newRowOnCurrentPage(java.lang.String) or newRowOnLastPage(java.lang.String) on the client.
Serializable	getRowKey(Serializable id) return id or -1 for new entity, for the new entity the rowKey will be -1 which makes it visible in a datatable
protected boolean	newOnLastPage() returns true when LazyDataModel.getPageSize() <= wrapped datasize.
protected abstract String	newRowOnCurrentPage(String table) javascript to execute when new row is on current page in datatable, called from editNew(java.lang.String)
protected abstract String	newRowOnLastPage(String table) javascript to execute when new row is on last page in datatable, called from editNew(java.lang.String)
void	prepareCreate() calls the super if no newEntity is present
void	remove(E entity) When the entity argument is transient call AbstractEntityController.setNewEntity(org.fryske_akademy.jpa.EntityInterface) with null otherwise call AbstractEntityController.destroy(org.fryske_akademy.jpa.EntityInterface) and AbstractEntityController.setSelected(org.fryske_akademy.jpa.EntityInterface) with null.
E	toDelete() return AbstractEntityController.getNewEntity() when it isn't null and AbstractEntityController.getSelected() is null, otherwise return AbstractEntityController.getSelected().

Method Detail

newRowOnLastPage

protected abstract String newRowOnLastPage(String table)

javascript to execute when new row is on last page in datatable, called from editNew(java.lang.String)

Parameters:

table -

Returns:

newRowOnCurrentPage

protected abstract String newRowOnCurrentPage(String table)

javascript to execute when new row is on current page in datatable, called from editNew(java.lang.String)

Parameters:

table -

Returns:

editNew

public void editNew(String table)
             throws InstantiationException,
                    IllegalAccessException

Calls prepareCreate() and either executes newRowOnCurrentPage(java.lang.String) or newRowOnLastPage(java.lang.String) on the client.

Parameters:

table -

Throws:

InstantiationException

IllegalAccessException

newOnLastPage

protected boolean newOnLastPage()

returns true when LazyDataModel.getPageSize() <= wrapped datasize. In this case the new entity, added in NewSupportingLazyModel.setWrappedData(java.lang.Object), will land on the last page.

Returns:

prepareCreate

public void prepareCreate()
                   throws InstantiationException,
                          IllegalAccessException

calls the super if no newEntity is present

Overrides:

prepareCreate in class AbstractEntityController<E extends EntityInterface>

Throws:

InstantiationException

IllegalAccessException

getRowKey

public Serializable getRowKey(Serializable id)

return id or -1 for new entity, for the new entity the rowKey will be -1 which makes it visible in a datatable

Parameters:

id -

Returns:

create

public E create(E e)
         throws Exception

calls the super and AbstractEntityController.setNewEntity(org.fryske_akademy.jpa.EntityInterface) with null.

Overrides:

create in class AbstractEntityController<E extends EntityInterface>

Parameters:

e -

Returns:

Throws:

Exception

remove

public void remove(E entity)
            throws Exception

When the entity argument is transient call AbstractEntityController.setNewEntity(org.fryske_akademy.jpa.EntityInterface) with null otherwise call AbstractEntityController.destroy(org.fryske_akademy.jpa.EntityInterface) and AbstractEntityController.setSelected(org.fryske_akademy.jpa.EntityInterface) with null. Decrements rowCount in the lazymodel and removes the entity from the wrapped data

Parameters:

entity -

Throws:

Exception

toDelete

public E toDelete()

return AbstractEntityController.getNewEntity() when it isn't null and AbstractEntityController.getSelected() is null, otherwise return AbstractEntityController.getSelected().

Returns:

disableDelete

public boolean disableDelete()

delete should be disabled when toDelete() is null;

Returns:

deleteTitle

public String deleteTitle()

show some usefull info to a user what is about to be deleted

Returns:
