Method Detail

canEdit

public boolean canEdit(RDFResource instance,
                       RDFProperty property,
                       Object value)

Description copied from interface: PropertyValueEditor

Checks whether this is able to edit values for a certain predicate.

Specified by:

canEdit in interface PropertyValueEditor

Returns:

true if this can edit such values

createDefaultValue

public Object createDefaultValue(RDFResource instance,
                                 RDFProperty property)

Description copied from interface: PropertyValueEditor

Creates a default value for a given predicate at a given subject. The hosting widget should call this method on each of its registered editors to see whether any of them defines a non-null default value.

Specified by:

createDefaultValue in interface PropertyValueEditor

Parameters:

instance - the RDFResource to create a default value for

property - the annotation predicate

Returns:

the default value or null if this does not define a default for this predicate

editValue

public Object editValue(Component parent,
                        RDFResource instance,
                        RDFProperty property,
                        Object value)

Description copied from interface: PropertyValueEditor

Edits a given value for a given resource/predicate pair. For example, after the user has double-clicked on the value, the host widget could iterate on all editors to see whether any of them is ready to edit this value (returning true).

Specified by:

editValue in interface PropertyValueEditor

Returns:

the new value (!= null) if this has handled editing for the value

mustEdit

public boolean mustEdit(RDFResource subject,
                        RDFProperty predicate,
                        Object value)

Description copied from interface: PropertyValueEditor

Checks whether this is the only way to edit values for a certain predicate. This is used to force editing of value types like xsd:date, where simple string input fields would not be sufficient.

Specified by:

mustEdit in interface PropertyValueEditor

Returns:

true if this can edit such values
