(Rob) Still considering the two approaches: using a hierarchy (i.e. ITimeSpaceLinkableComponent extends IBaseLinkableComponent, MyComponent implements ITimeSpaceLinkableComponent) or composition (i.e. MyComponent implements ILinkableComponent, ILinkableComponentTimeSpaceExtension). Should consider the effect when adding a linkable component interface for the loop method(s) or for the FRAMES dictionary support. Also see how OGC spatial element sets can be added as an extension and how this effects the interfaces.
Alternative 1 (interface hierarchy):
| Code Block |
|---|
IBaseLinkableComponent { base methods };
ITimeSpaceLinkableComponent extends IBaseLinkableComponent { time-space methods };
IParallelTimeSpaceLinkableComponent extends ITimeSpaceLinkableComponent { loop methods };
IDictionaryLinkableComponent extends IBaseLinkableComponent { dictionary methods };
IParallelDictionaryLinkableComponent extends IDictionaryLinkableComponent { loop methods };
MyParallelTimeSpaceComponent implements IParallelTimeSpaceLinkableComponent {};
MyParallelDictionaryComponent implements IParallelDictionaryLinkableComponent {};
|
Alternative 2 (uncoupled interfaces):
| Code Block |
|---|
ILinkableComponent { base methods };
ILinkableComponentTimeSpaceExtension { time-space methods };
ILinkableComponentParallelExtension { loop methods };
ILinkableComponentDictionaryExtension { dictionary methods };
MyParallelTimeSpaceComponent implements ILinkableComponent, ILinkableComponentTimeSpaceExtension, ILinkableComponentParallelExtension {};
MyParallelDictionaryComponent implements ILinkableComponent, ILinkableComponentDictionaryExtension, ILinkableComponentParallelExtension {};
