Method Detail

hasProperty

<X> boolean hasProperty(PropertyTag<X> tag)

Does this class support the specified property. A false return value is a definitive statement that the property will not be available in any records this UsageProducer retrieves from the database though the properties may exist during the parse phase. A true return value indicates that some of the records returned may contain the specified property.

Specified by:

hasProperty in interface PropertyTargetFactory

Parameters:

tag -

Returns:

boolean

getImplemenationInfo

java.lang.String getImplemenationInfo(PropertyTag<?> tag)

Return a text description of how the property is implemented. if the object is composite this may generate a list of different implementations.

Parameters:

tag - PropertyTag

Returns:

String
