All Implemented Interfaces:
IRowHideShowLayer, ILayer, ILayerListener, IUniqueIndexLayer, IPersistable
public class GlazedListsRowHideShowLayer<T> extends AbstractLayerTransform implements IRowHideShowLayer, IUniqueIndexLayer
Adds the functionality for manually hiding rows in a NatTable that is based on GlazedLists. Technically it will filter items by id in the FilterList.

Note: If you want to add row hide/show AND filtering to your NatTable, you need to use the DefaultGlazedListsStaticFilterStrategy and add the Matcher that is used by this command as a static MatcherEditor. Otherwise these two functions will not work correctly together.

  • Field Details

    • PERSISTENCE_KEY_HIDDEN_ROW_IDS_COUNT

      public static final String PERSISTENCE_KEY_HIDDEN_ROW_IDS_COUNT
      Key for persisting the number of hidden row id's. This is necessary because the id's are serializables and reading them againd by ObjectInputStream need to know how long to read.

    • GlazedListsRowHideShowLayer

      public GlazedListsRowHideShowLayer(ILayer underlyingLayer, IRowDataProvider<T> rowDataProvider, IRowIdAccessor<T> rowIdAccessor)
      Creates a GlazedListsRowHideShowLayer for adding row hide/show for GlazedLists based NatTables. Using this constructor will only instantiate this layer. To use this correctly you need to register the local row hide MatcherEditor against the FilterList yourself.
      Parameters:
      underlyingLayer - The underlying layer.
      rowDataProvider - The IRowDataProvider needed to get the object at a given position so it is possible to retrieve the id that is used for filtering.
      rowIdAccessor - The IRowIdAccessor that is used to extract the id out of the row object. This is necessary to determine the row object to hide in terms of content.

    • GlazedListsRowHideShowLayer

      public GlazedListsRowHideShowLayer(ILayer underlyingLayer, IRowDataProvider<T> rowDataProvider, IRowIdAccessor<T> rowIdAccessor, ca.odell.glazedlists.FilterList<T> filterList)
      Creates a GlazedListsRowHideShowLayer for adding row hide/show for GlazedLists based NatTables. Using this constructor will add the MatcherEditor to the given FilterList. This might not work correctly in combination with other filters like e.g. the filter row.
      Parameters:
      underlyingLayer - The underlying layer.
      rowDataProvider - The IRowDataProvider needed to get the object at a given position so it is possible to retrieve the id that is used for filtering.
      rowIdAccessor - The IRowIdAccessor that is used to extract the id out of the row object. This is necessary to determine the row object to hide in terms of content.
      filterList - The FilterList to apply the local row hide Matcher to.

    • GlazedListsRowHideShowLayer

      public GlazedListsRowHideShowLayer(ILayer underlyingLayer, IRowDataProvider<T> rowDataProvider, IRowIdAccessor<T> rowIdAccessor, ca.odell.glazedlists.matchers.CompositeMatcherEditor<T> matcherEditor)
      Creates a GlazedListsRowHideShowLayer for adding row hide/show for GlazedLists based NatTables. Using this constructor will add the MatcherEditor to the given CompositeMatcherEditor. This way it is possible to add more filter logic than only the row hide filter.
      Parameters:
      underlyingLayer - The underlying layer.
      rowDataProvider - The IRowDataProvider needed to get the object at a given position so it is possible to retrieve the id that is used for filtering.
      rowIdAccessor - The IRowIdAccessor that is used to extract the id out of the row object. This is necessary to determine the row object to hide in terms of content.
      matcherEditor - The CompositeMatcherEditor to which the local row hide Matcher should be added.

      public void hideRowPositions(Collection<Integer> rowPositions)
      Hide the rows at the given positions. Will collect the id's of the rows at the given positions as this layer operates on content rather than positions.

      hideRowIndexes in interface IRowHideShowLayer
      Parameters:
      rowIndexes - The indexes of the rows to hide.

    • hideRowIndexes

      public void hideRowIndexes(Collection<Integer> rowIndexes)
      Hide the rows at the given indexes. Will collect the id's of the rows at the given positions as this layer operates on content rather than positions.
      Specified by:
      hideRowIndexes in interface IRowHideShowLayer

    • showRowIndexes

      public void showRowIndexes(Collection<Integer> rowIndexes)
      Show the rows with the given indexes again. Will collect the id's of the rows at the given positions as this layer operates on content rather than positions.
