It does not effect corelinux but uses the classes and/or abstractions provided.

Create New Semaphore Group use case from package Solution Domain A developer may optionally create a new Semaphore Group type. Create New Semaphore Type use case from package Solution Domain A developer may optionaly create a new Semaphore type. Create Semaphore use case from package Solution Domain The caller creates a Semaphore regardless of type. Create Semaphore Group use case from package Solution Domain Create Semaphore Group realizes the kernel semaphore group "create" semantic in that the type of group type is irrelevent. Create Semaphore Group Type use case from package Solution Domain Create Semaphore Group realizes the "create" semantic in that the implementor assumes that the group has not yet been created. This is a specialized case where this group only produces Semaphores of the specific type. Create Semaphore Type use case from package Solution Domain The caller requests a semaphore to be created of a specific type. D Data package Destroy Semaphore use case from package Solution Domain The caller returns the specific semaphore to the system. Destroy Semaphore Group use case from package Solution Domain Destroy Semaphore Group is the corollary to the Create Semaphore Group where the caller has no more use of the group. This actually removes, or tries to remove, the Semaphore Group from the system. Developer actor from package Participants Developer extends classes for use in a solution space Developer class from package Participants Developer extends classes for use in a solution space E Extend One-to-One Semaphore use case from package Solution Domain A Developer can extend a One-to-One Semaphore type. Extends Many-to-One Semaphore use case from package Solution Domain A Developer can extend a Many-to-One Semaphore type. Extends One-to-Many Semaphore use case from package Solution Domain A Developer can extend a One-to-Many Semaphore type. Extends Semaphore Group use case from package Solution Domain A Developer extends a Semaphore Group. G Get Semaphore use case from package Solution Domain The caller requests an instance of a already created semaphore. Get Semaphore Group use case from package Solution Domain Get Semaphore Group realizes the "open" semantic in that the implementor assumes that the group has already been created. I Implementor actor from package Participants Implementor is a developer that uses either the corelinux or extension types into solution space applications. Implementor class from package Participants Implementor is a developer that uses either the corelinux or extension types into solution space applications. L Lock Semaphore use case from package Solution Domain The caller requests a lock on a specific semaphore with regards to the semantic of the semaphore type. M Modify Semaphore use case from package Solution Domain A request is made to modify the state of the semaphore. P Participants package Roles defined by the requirement. Q Query Semaphore use case from package Solution Domain The caller requests information about a specific semaphore. R Release Locked Semaphore use case from package Solution Domain The caller designates that the specific semaphore is unlocked with regards to the semantic of the semaphore type. Return Semaphore Group use case from package Solution Domain Return Semaphore Group is the corollary to the Get Semaphore Group where the caller has no more use of the group. It may be that the return destroys the group if it is not used elsewhere. S Solution Domain package The Solution Domain represents the implementors application, library, or process domain. It does not effect corelinux but uses the classes and/or abstractions provided.
