C++ classes

Use the DFSMSrmm RmmApi class to prepare the environment for using the RmmCommand class to use the DFSMSrmm TSO subcommands with the API. You can also use the RmmTransaction class that makes use of the RmmApi and RmmCommand classes. All of these classes are defined in the DFSMSrmm header file EDGXHCLU.

Class	Description
RmmInterface	This is the superclass for DFSMSrmm processing. This class provides methods that are common to the classes RmmApi and RmmCommand. This class cannot be instantiated.
RmmApi	This class extends the RmmInterface class. Use this class to create an object to initiate a communication session with DFSMSrmm. You must create an instance of this class before you use class RmmCommand. This instance can be used to create one or more RmmCommand objects to enable you to run DFSMSrmm subcommands. You need one RmmApi object for each Multiple Virtual Storage (MVS™) TCB under which DFSMSrmm runs. To end the communication session with DFSMSrmm and to no longer run subcommands, delete the RmmApi object.
RmmCommand	This class extends the RmmInterface class. Use this class to process a DFSMSrmm TSO subcommand. You must pass a reference to the RmmApi object when you instantiate an instance of this class. You can instantiate multiple instances of the RmmCommand class to process multiple commands in parallel. For example, you can use the output from a SEARCH command to issue LIST subcommands.
RmmTransaction	This class makes use of the RmmApi and RmmCommand classes. Instantiate an instance of this class, if you want to use the runCommandXml method.
