This implementation of BESContainerStorage stores volatile containers in memory for the duration of this process. A list of containers is stored in the object. The look_for method simply looks for the specified symbolic name in the list of containers and returns if a match is found. Containers can be added to this instance as long as the symbolic name doesn't already exist.

This method adds the passed container to the list of volatile containers. The passed container is owned by the list if added and should not be deleted by the caller.
If a container with the symbolic name of the passed container is already in the list then an exception is thrown.

BESContainerStorageExcpetion | if the passed container is null |
BESContainerStorageExcpetion | if no type is specified in the passed container |

virtual |
If a container other than a BESFileContainer is to be added to the list then a derived class of BESContainerStorageVolatile should call the protected add_container method that takes an already built container. This method adds a container represented by a data file.
sym_name | symbolic name of the container being created |
real_name | real name of the container |
type | type of data represented by this container |
BESInternalError | if no type is specified |
BESInternalError | if a container with the passed symbolic name already exists. |

For each container in this persistent store, add infomation about each of those containers. The information added to the information object includes a line for each container within this persistent store which includes the symbolic name, the real name, and the data type, separated by commas.
In the case of this persistent store information from each container added to the volatile list is added to the information object.
info | object to store the container and persistent store information |
