Method Detail

getCurrentPage

public List<Map<String,Serializable>> getCurrentPage()

Description copied from interface: PageProvider

Returns the current page of results.

This method is designed to be called from higher levels. It therefore ensures cheapness of repeated calls, rather than data consistency. There is a refresh() method for that.

Specified by:

getCurrentPage in interface PageProvider<Map<String,Serializable>>

Specified by:

getCurrentPage in class AbstractPageProvider<Map<String,Serializable>>

Returns:

the current page

getCurrentSelectPage

public PageSelections<Map<String,Serializable>> getCurrentSelectPage()

Description copied from interface: PageProvider

Returns the current page of results wrapped in a PageSelection item.

By default, no entry is selected, unless PageProvider.setSelectedEntries(List) has been called before.

Specified by:

getCurrentSelectPage in interface PageProvider<Map<String,Serializable>>

Overrides:

getCurrentSelectPage in class AbstractPageProvider<Map<String,Serializable>>

getCurrentQuery

public String getCurrentQuery()

refresh

public void refresh()

Description copied from interface: PageProvider

Forces refresh of the current page.

Specified by:

refresh in interface PageProvider<Map<String,Serializable>>
