Detailed Description

implementation of BESContainerStorageVolatile that represents a list of NCML requests

Each of the containers stored in the NCMLContainerStorage represents a NCML request. When accessed the container will make the NCML request in order to create the target response.

Member Function Documentation

void NCMLContainerStorage::add_container	(	const string &	s_name,
		const string &	r_name,
		const string &	type
	)

virtual

adds a container with the provided information

Parameters

s_name	symbolic name for the container
r_name	the wcs request url
type	ignored. The type of the target response is determined by the NCML request with the format parameter

Reimplemented from BESContainerStorageVolatile.

Here is the call graph for this function:

void BESContainerStorageVolatile::add_container ( BESContainer * c )

protectedvirtualinherited

add the passed container to the list of containers in volatile storage

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.

Parameters

c	container to add to the list

Exceptions

BESContainerStorageExcpetion	if the passed container is null
BESContainerStorageExcpetion	if no type is specified in the passed container
BESContainerStorageExcpetion	if a container with the passed symbolic name already exists.

removes a container with the given symbolic name from the list and deletes it.

Parameters

s_name symbolic name for the container

Returns: true if successfully removed and false otherwise

Implements BESContainerStorage.

bool BESContainerStorageVolatile::del_containers ( )

removes all container

This method removes all containers from the persistent store. It does not delete the real data behind the container.

Returns: true if successfully removed and false otherwise

void NCMLContainerStorage::dump ( ostream & strm ) const

determine if the given container is data and what servies are available for it

Parameters

virtualinherited

looks for the specified container using the symbolic name passed

If a match is made with the symbolic name then the stored container is duplicated and returned to the user. If not, 0 is returned.

Parameters

sym_name symbolic name of the container to look for

Returns: a new BESContainer instance using the ptr_duplicate method on BESContainer

void BESContainerStorageVolatile::show_containers ( BESInfo & info )

virtualinherited

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 information from each container added to the volatile list is added to the information object.
