Interface OWLWidgetMetadata

All Known Implementing Classes:
  AnnotationsWidgetMetadata, DataRangeFieldWidgetMetadata, HeaderWidgetMetadata, MultiLiteralWidgetMetadata, MultiResourceWidgetMetadata, OWLDateTimeWidgetMetadata, OWLDateWidgetMetadata, OWLTimeWidgetMetadata, RDFListWidgetMetadata, RDFSSubClassOfWidgetMetadata, SingleLiteralAreaWidgetMetadata, SingleLiteralWidgetMetadata, SingleResourceWidgetMetadata

    public interface OWLWidgetMetadata

An interface for objects that provide metadata about a widget type. This is used by the OWLWidgetMapper to determine whether a certain widget class shall be chosen for a certain class/property combination.

The widget class should register an implementation of this in a static block.

Field Summary
`static int` | `DEFAULT` Indicates that this widget is the default widget unless some other plugin declares a widget with higher suitability
`static int` | `NOT_SUITABLE` Indicates that this widget is not suitable for the given class/property combination
`static int` | `SUITABLE` Indicates that this widget is suitable (but not necessarily default) for the given class/property combination

Method Summary
`int` | `getSuitability(RDFSNamedClass cls, RDFProperty property)` Gets the suitability index of a widget for a given class/property pair.

Field Detail

### NOT_SUITABLE

    static final int NOT_SUITABLE

  Indicates that this widget is not suitable for the given class/property combination

    Constant Field Values

### SUITABLE

    static final int SUITABLE

  Indicates that this widget is suitable (but not necessarily default) for the given class/property combination

  See Also:
    Constant Field Values

### DEFAULT

    static final int DEFAULT

  Indicates that this widget is the default widget unless some other plugin declares a widget with higher suitability

  See Also:
    Constant Field Values

Method Detail

### getSuitability

    int getSuitability(RDFSNamedClass cls,
                       RDFProperty property)

  Gets the suitability index of a widget for a given class/property pair. The suitability indicates whether a widget shall be selected as default widget on a form, or whether it shall be listed as one of the options in the form configuration component.

  The system widgets of Protege-OWL all return one of the predefined constants `NOT_SUITABLE`, `SUITABLE` or `DEFAULT`. Custom widget classes can also return the same constants, or they can return higher values to override the current default. For example, returning `DEFAULT + 1` will make sure that the widget will have higher preferences than any of the system widgets.

  Parameters:
    `cls` - the named class of the form
    `property` - the property to get the suitability for
  Returns:
    an index >= 0
