Get all objects from a GWT CellTable

Simple question: I have a CellTable filled with Keyword objects. Now, I would like to retrieve all the Keywords in that CellTable. Is this possible? If not, why? Surely there must be a way...

I can not understand how this is so hard (well maybe it isn't but I just can't seem find the answer for the life of me).

Some code to clarify:

//my celltable
private CellTable<Keyword> ctKeywordsLinked = new CellTable<Keyword>();

//listdataprovider to fill my celltable with
private ListDataProvider<Keyword> dataProviderLinkedKeywords = new ListDataProvider<Keyword>();

//add 4 keyword objects to the listdataprovider to fill the celltable
dataProviderLinkedKeywords.getList().add(new Keyword);
dataProviderLinkedKeywords.getList().add(new Keyword);
dataProviderLinkedKeywords.getList().add(new Keyword);
dataProviderLinkedKeywords.getList().add(new Keyword);

So now that I have my celltable filled, I would like to retrieve those 4 keywords without touching the listdataprovider. I hope everything is a bit more cleared up :-)

Solution

  • CellTable has method getKeyProvider, which returns object containing data under ProvidesKey interface.

    You create ListDataProvider and pass it to cell table, so you can get that provider from cell table again at any time:

    ListDataProvider provider = (ListDataProvider)cellTable.getKeyProvider();
provider.getList().get(0); // get first Keyword
