Base interface for items that can be used in a CanvasComponent.
Inheritance Hierarchy
Implemented Interfaces
Remarks
Most prominently this is the interface all graph elements used in IGraph implement.
It adds no functionality over the ILookup and ITagOwner interfaces it inherits.

Methods
Returns an instance that implements the given type or null.
Remarks
Typically, this method will be called to obtain a different view or aspect of the current instance. This is quite similar to casting or using a super type or interface of this instance, but is not limited to inheritance or compile-time constraints. An instance implementing this method is not required to return non-
null implementations for the types, nor does it have to return the same instance any time. Also, it depends on the type and context whether the instance returned stays up to date or needs to be re-obtained for further use.Type Parameters
- T
Parameters
options - Object
A map of options to pass to the method.
A map of options to pass to the method.
- type - Constructor<T>
- the type for which an instance shall be returned
Returns
- ↪T?
- an instance that is assignable to the type or
null
