Interface FeatureGroupMember

All Superinterfaces:

Feature, FeatureNameProvider

All Known Subinterfaces:

StyledFeatureGroupMember

All Known Implementing Classes:

FeatureGroupWrapper, StyledFeatureGroupWrapper

public interface FeatureGroupMember
extends Feature, FeatureNameProvider

Features implementing FeatureGroupMember are grouped according their group id. Note that each group has its own layer in MappingComponent which is a child of the feature layer. If there is no group layer for the id returned by getGroupId(), a new layer is created and added to the feature layer.

Method Detail

getGroupName

String getGroupName()

Returns the the display name of the group. This name can be used for GUI purposes e.g. for displaying groups in the layer overview.

Returns:

group display name

getGroupId

String getGroupId()

Returns the group id.

Returns:

group id

getFeature

Feature getFeature()

Return the actual feature belonging to the FeatureGroupMember implementation. This method is needed as most of the (current) Features do not implement FeatureGroupMember immediately (as this is quite new interface) leading to wrapper implementations. However, there might occur problems with using collections in this context (which can NOT be solved just with impementing Object.hashCode() and Object.equals(java.lang.Object) (see Lagis as example)). Therefore, only the underlying Feature is used for such purposes such as working with hash maps (Feature as key).

Returns:

underlying feature
