Holder
A holder is a component created by DispMan that lists the resource inventory for each resource dispenser.
The holder and resource dispenser communicate to request resources of a particular type. The follow relationships exist between the holder and resource dispenser:
- The holder requests a resources from the resource dispenser. The resource dispenser either returns an available resource or creates a new one.
- The holder notifies the resource dispenser that an application no longer needs a resource and returns it to the resource pool.
- The holder and the resource dispenser maintain the size of the resource pool.
