This impelementation of BESContainerStorage loads container information from a file. The name of the file is determined from the bes configuration file. The key is:
BES.Container.Persistence.File.<name>
where <name> is the name of this persistent store.
The format of the file is:
<symbolic_name> <real_name> <data type>
where the <symbolic_name> is the symbolic name of the container, the <real_name> represents the physical location of the data, such as a file, and the <data type> is the type of data being represented, such as netcdf, cedar, etc...
One container per line, can not span multiple lines

BESContainerStorageFile::BESContainerStorageFile | ( | const string & | n | ) |
pull container information from the specified file
Constructs a BESContainerStorageFile from a file specified by a key in the bes configuration file. The key is constructed using the name of this persistent store.
BES.Container.Persistence.File.<name>
where <name> is the name of this persistent store.
The containers are then read into memory. The format of the file is as follows.
<symbolic_name> <real_name> <data type>
where the symbolic name is the symbolic name of the container, the <real_name> represents the physical location of the data, such as a file, and the <data type> is the type of data being represented, such as netcdf, cedar, etc...
One container per line, can not span multiple lines
n | name of this persistent store |
BESContainerStorageException | if the file can not be opened or if there is an error in reading in the container information. |

BESContainer * BESContainerStorageFile::look_for | ( | const string & | sym_name | ) | [virtual] |
looks for the specified container in the list of containers loaded from the file.
If a match is made with the specified symbolic name then a BESFileContainer instance is created using the the information found (real name and container type). If not found then NULL is returned.
sym_name | name of the container to look for |

adds a container with the provided information
This method adds a container to the persistence store with the specified information. This functionality is not currently supported for file persistence.
s_name | symbolic name for the container | |
r_name | real name for the container | |
type | type of data represented by this container |

bool BESContainerStorageFile::del_container | ( | const string & | s_name | ) | [virtual] |
removes a container with the given symbolic name
This method removes a container to the persistence store with the given symbolic name. It deletes the container. The container is NOT removed from the file from which it was loaded, however.
s_name | symbolic name for the container |
Implements BESContainerStorage.
Definition at line 204 of file BESContainerStorageFile.cc.
bool BESContainerStorageFile::del_containers | ( | ) | [virtual] |
removes all containers
This method removes all containers from the persistent store. The container is NOT removed from the file from which it was loaded, however.
Implements BESContainerStorage.
Definition at line 227 of file BESContainerStorageFile.cc.
void BESContainerStorageFile::show_containers | ( | BESInfo & | info | ) | [virtual] |
show information for each container in this persistent store
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 all of the containers loaded from the file specified by the key BES.Container.Persistence.File.<store_name> is added to the information object.
info | object to store the container and persistent store information into |
