public class TLcdWCSProxyModel extends Object implements ILcd2DBoundsIndexedModel
TLcdWCSProxy
object. The model has a
TLcdWCSProxyModelDescriptor
, through which the capabilities of the WCS
service that the model connects to can be retrieved.
Note that if the TLcdWCSProxy
object in this model is configured to use
asynchronous transfers, the model will generate model changed events to
notify users that the internal state of the TLcdWCSProxy
has changed.
A TLcdWCSProxyModel
cannot be instantiated directly. Use
TLcdWCSProxyModelFactory
to create WCS proxy models.

Models that support this operation may place limitations on what elements may be added to this model. For example,
implementations that are based on a spatial indexing structure will require that elements implement
ILcdBounded
.
When adding an element, the user should make sure that canAddElement(aElement)
holds, and that the
element's geometry is expressed in the same model reference as this model. It is generally undefined what happens
if an invalid element is added.
Implementations of this interface should clearly specify in their documentation any restrictions on what elements
may be added. Although it is unspecified what happens if the preconditions are not met, implementations are
encouraged to throw meaningful exceptions (for example, NullPointerException, IllegalArgumentException,
ClassCastException, UnsupportedOperationException
), whenever possible.

Registers the specified model listener to receive notifications of model changes on this model.
Model changes are sent out when an element has been added, removed or changed. Model changes can be sent out
individually, grouped or silently applied without notifications, depending on the ILcdFireEventMode
that was specified with the change.
In case you need to register a listener which keeps a reference to an object with a shorter life-time than this model,
you can use a ALcdWeakModelListener
instance as model listener.
