public boolean canConvert(Object o,
                          ReferenceContext context)

Description copied from interface: ValueToReferenceConverterSPI

Can this SPI implementation convert the specified object to an ExternalReferenceSPI? This test should be as lightweight as possible, and will usually be based on the Class of the object supplied.

Specified by:

canConvert in interface ValueToReferenceConverterSPI

context - a ReferenceContext to use if required by the plugin, the ability to convert should be interpreted in the scope of this context. In general the context probably not used by most implementations but it's here if required.

Returns:

whether this converter is applicable to the specified object

convert

public ExternalReferenceSPI convert(Object o,
                                    ReferenceContext context)
                             throws ValueToReferenceConversionException

Return a FileReference

Specified by:

convert in interface ValueToReferenceConverterSPI

context - a ReferenceContext to use, if required, during construction of the new external reference

Returns:

A new instance of ExternalReferenceSPI which references, as far as possible, the value represented by the specified object

Throws:

ValueToReferenceConversionException - if any problem occurs during the conversion
