(Constructor)

source code

A RDMCPStorageObject can be instantiated in two ways:

Creation mode: If size is specified, the underlying configFS object will be created with that parameter. No RDMCPStorageObject with the same name can pre-exist in the parent Backstore in that mode, or instantiation will fail.
Lookup mode: If size is not set, then the RDMCPStorageObject will be bound to the existing configFS object in the parent Backstore having the specified name. The underlying configFS object must already exist in that mode, or instantiation will fail.

Parameters:
