  • Method Details

    • select

      boolean select(FeatureReference reference)
      Adds a feature to the selection.
      Parameters:
      reference - the selected feature reference
      Returns:
      true if the feature was not selected before selecting it

    • deselect

      boolean deselect(FeatureReference reference)
      Removes a feature from the selection.
      Parameters:
      reference - the deselected feature reference
      Returns:
      true if the feature was selected before deselecting it

    • selectAll

      void selectAll() throws DataException
      Selects all values.
      Throws:
      DataException - if there is an error selecting all values

    • deselectAll

      void deselectAll() throws DataException
      Deselects all values.
      Throws:
      DataException - if there is an error deselecting all values

    • isSelected

      boolean isSelected(FeatureReference reference)
      Returns if a feature is selected.
      Parameters:
      reference - to check
      Returns:
      if it is selected

    • reverse

      void reverse()
      Reverses the selection. Currently selected objects will become the not selected ones, so any other object will be a selected one.

    • getSelectedCount

      long getSelectedCount()
      Returns the number of selected values.
      Returns:
      the number of selected values

    • referenceIterator

      Iterator<FeatureReference> referenceIterator()
      Returns an unmodifiable Iterator of selected feature references.
      Returns:
      the iterator of selected feature references

    • referenceIterable

      Iterable<FeatureReference> referenceIterable()

    • isAvailable

      boolean isAvailable()
