GabrielRado :
I have an Angular app that shows a list of entities and I have a 'show more' button that increments page number and uses this method:
Page<myEntity> result = myRepo.findByAttr(attr, page);
I format this result
and send it via REST's JSON. I want to disable 'show more' button if there's no further pages to get. There's a 'frameworkie' specific way to retrieve this number or I should use findAll()
and count through this list?
pvpkiran :
This is the source code of Page
interface
public interface Page<T> extends Slice<T> {
/**
* Returns the number of total pages.
*
* @return the number of total pages
*/
int getTotalPages();
/**
* Returns the total amount of elements.
*
* @return the total amount of elements
*/
long getTotalElements();
/**
* Returns a new {@link Page} with the content of the current one mapped by the given {@link Converter}.
*
* @param converter must not be {@literal null}.
* @return a new {@link Page} with the content of the current one mapped by the given {@link Converter}.
* @since 1.10
*/
<S> Page<S> map(Converter<? super T, ? extends S> converter);
}
You have getTotalElements()
to get the total number of matching element.
getTotalPages()
will give total number of pages.
