org.eclipse.jpt.common.utility
Interface Association<K,V>

Type Parameters:

K - the type of the association's key

V - the type of the association's value

public interface Association<K,V>

Straightforward definition of an object pairing. The key is immutable.

Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.
