    • replace

      void replace(ForeignKey foreignKey, Collection<Entity> foreignKeyValues)
      For every entity in this table model, replaces the foreign key instance bearing the primary key with the corresponding entity from foreignKeyValues, useful when attribute values have been changed in the referenced entity that must be reflected in the table model.
      Parameters:

      Returns:
      the State controlling whether this table model is editable

    • backgroundColor

      Object backgroundColor(int row, Attribute<?> attribute)
      Parameters:
      row - the row for which to retrieve the background color
      attribute - the attribute for which to retrieve the background color
      Returns:
      an Object representing the background color for this row and attribute, specified by the row entity
      See Also:

    • foregroundColor

      Object foregroundColor(int row, Attribute<?> attribute)
      Parameters:
      row - the row for which to retrieve the foreground color
      attribute - the attribute for which to retrieve the foreground color
      Returns:
      an Object representing the foreground color for this row and attribute, specified by the row entity
      See Also:

    • attributes

      ValueSet<Attribute<?>> attributes()
      Returns the ValueSet controlling which attributes are included when selecting entities to populate this model. Note that an empty ValueSet indicates that the default select attributes should be used.
      Returns:
      the ValueSet controlling the selected attributes

    • limit

      Value<Integer> limit()
      Returns the Value controlling the maximum number of rows to fetch via the underlying query the next time this table model is refreshed, a null value means all rows should be fetched
      Returns:
      the value controlling the limit

    • orderBy

      Value<OrderBy> orderBy()
      Controls the order by clause to use when selecting the data for this model. Setting this value to null reverts back to the default order by for the underlying entity, if one has been specified
      Returns:
      the value controlling the order by clause
      See Also:

    • deleteSelected

      Collection<Entity> deleteSelected() throws DatabaseException

      the deleted entities
      Throws:
      DatabaseException - in case of a database exception
      CancelException - in case the user cancels the operation
      IllegalStateException - in case this table model has no edit model or if the edit model does not allow deleting

    • conditionRequired

      State conditionRequired()
      Returns a State controlling whether this table model should display all underlying entities when no query condition has been set. Setting this value to 'true' prevents all rows from being fetched by accident, when no condition has been set, which is recommended for tables with a large underlying dataset.
      Returns:
      a State specifying whether this table model requires a query condition
