Class Description:
|
|||
|
|
|
|||
|
|
A CRmsStorageInfo represents storage information about a Cartridge, Partition, or
|
|||
|
|
MediaSet. Various statistics about an element are kept for an object of this
|
|||
|
|
type. These include the number of times a Cartridge, or Partition has been put into
|
|||
|
|
the element or taken from (get) the element.
