java.lang.Object
org.eclipse.emf.common.notify.impl.AdapterImpl
org.eclipse.ohf.stem.definitions.adapters.spatial.SpatialProviderAdapter
org.eclipse.ohf.stem.definitions.adapters.spatial.geo.LatLongProviderAdapter
- All Implemented Interfaces:
- org.eclipse.emf.common.notify.Adapter, org.eclipse.emf.common.notify.Adapter.Internal, LatLongProvider, SpatialProvider
public class LatLongProviderAdapter
- extends SpatialProviderAdapter
- implements LatLongProvider
This class adapts Identifiable
's to
LatLongProvider
's. It extracts the lat/long data by examining
the spatial attribute of an Identifiable
's dublin
core instance. Typically, the value of the attribute will be recognized by
the adapter and the values returned. If the attribute does not have a value
or the format of the value is not recognized, then an empty list will be
returned.
The format recognized by the adapter is a URI with the scheme defined by the
constant STEM_SPATIAL_SCHEME

LatLongProviderAdapter
public LatLongProviderAdapter()
registerLatLongDataProvider
public static void registerLatLongDataProvider(java.lang.String scheme,
LatLongDataProvider latLongDataProvider)
- Add the latLongDataProvider to the collection of available to this
adapter
- Parameters:
scheme
- the key of the URI's that the data provider processeslatLongDataProvider
- the data provider
getLatLongDataProviders
public static java.util.Map<java.lang.String,LatLongDataProvider> getLatLongDataProviders()
- Returns:
- the map between scheme's and their lat/long data providers
isAdapterForType
public boolean isAdapterForType(java.lang.Object type)
- Specified by:
isAdapterForType
in interface org.eclipse.emf.common.notify.Adapter
- Overrides:
isAdapterForType
in class SpatialProviderAdapter
- See Also:
AdapterImpl.isAdapterForType(java.lang.Object)
getLatLong
public LatLong getLatLong()
- Specified by:
getLatLong
in interface LatLongProvider
- Returns:
- the lat/long value
getLatLongNoWait
public LatLong getLatLongNoWait()
- Description copied from interface:
LatLongProvider
- This is just like
LatLongProvider.getLatLong()
except that it returns an empty
instance of LatLong
if the data has not been retrieved yet. As a
side effect, it immediately schedules a Job
to retrieve the data.
As such, a future call might produce a fully populated result.
- Specified by:
getLatLongNoWait
in interface LatLongProvider
- Returns:
- the lat/long value
