Method Detail

findSelectedInPage

protected void findSelectedInPage()

firstPage

public void firstPage()

getList

public List<T> getList()

Description copied from interface: ListBrowser

Retrieves the list of the browsing objects. This list will be the content of the repository on which this browser is based, filtered using the criteria specified by setCriteria. The list will be sorted using the property specified by setOrder. If something causes the changing of the list of browsing objects a PropertyChange event will be fired.

Specified by:

getList in interface ListBrowser<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

Overrides:

getList in class ListBrowserImpl<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

Returns:

the list of the browsing objects

refreshPageLimits

protected void refreshPageLimits()

invalidateContent

protected void invalidateContent()

Overrides:

invalidateContent in class ListBrowserImpl<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

nextPage

public void nextPage()

Specified by:

nextPage in interface PagedListBrowser<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

getHasNextPage

public boolean getHasNextPage()

Specified by:

getHasNextPage in interface PagedListBrowser<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

previousPage

public void previousPage()

Specified by:

previousPage in interface PagedListBrowser<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

getHasPreviousPage

public boolean getHasPreviousPage()

Specified by:

getHasPreviousPage in interface PagedListBrowser<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

Specified by:

gotoPage in interface PagedListBrowser<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

getCurrentPageNumber

public Long getCurrentPageNumber()

Specified by:

getCurrentPageNumber in interface PagedListBrowser<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

getTotalPages

public Long getTotalPages()

Specified by:

getPageSize

public int getPageSize()

Specified by:

getPageSize in interface PagedListBrowser<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

setFilter

public void setFilter(it.amattioli.dominate.Filter filter)

Description copied from interface: ListBrowser

Set the criteria to be used to filter the browsing objects. The ListBrowser.getList() method will return only the objects that satisfy the specified criteria. The browser will listen on property changes of the filter bean so to refresh the browsing objects accordingly.

Specified by:

setFilter in interface ListBrowser<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

Overrides:

setFilter in class ListBrowserImpl<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

Parameters:

filter - the criteria that will be used to filter the browsing objects

getHasNext

public boolean getHasNext()

Description copied from interface: ListBrowser

Indicate if there is an object next to the currently selected object.

Specified by:

getHasNext in interface ListBrowser<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

Overrides:

getHasNext in class ListBrowserImpl<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

Returns:

true if there is an object next to the currently selected object, false if the currently selected object is the last in the list

getHasPrevious

public boolean getHasPrevious()

Description copied from interface: ListBrowser

Indicate if there is an object previous to the currently selected object.

Specified by:

getHasPrevious in interface ListBrowser<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

Overrides:

getHasPrevious in class ListBrowserImpl<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

Returns:

true if there is an object previous to the currently selected object, false if the currently selected object is the first in the list

next

public void next()

Description copied from interface: ListBrowser

Move the selection to the object next to the currently selected object. If the currently selected object is the last of the list, nothing will happen.

Specified by:

next in interface ListBrowser<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

Overrides:

next in class ListBrowserImpl<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

previous

public void previous()

Description copied from interface: ListBrowser

Move the selection to the object previous to the currently selected object. If the currently selected object is the first of the list, nothing will happen.

Specified by:

previous in interface ListBrowser<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

Overrides:

previous in class ListBrowserImpl<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

select

public void select(int index)

Description copied from interface: ListBrowser

Select an object using its index inside the list retrieved using ListBrowser.getList(). After the selection a SelectionEvent will be notified to all the objects that has been registered using #addContentChangeListener(BrowserSelectionListener).

Specified by:

select in interface ListBrowser<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

Overrides:

select in class ListBrowserImpl<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>

Parameters:

index - the index inside the list retrieved using ListBrowser.getList() of the object to be selected

getListAll

public List<T> getListAll()

Specified by:

getListAll in interface PagedListBrowser<I extends Serializable,T extends it.amattioli.dominate.Entity<I>>
