## Member Functions

const std::string & connectionString,
int minSessions = 1,
int maxSessions = 32,

SessionPool & getPool(
const std::string & name
);

Returns a SessionPool reference. Throws NotFoundException if session is not found.

### has

bool has(
const std::string & name
) const;

Returns true if the requested name exists, false otherwise.

### isActive

bool isActive(
const std::string & sessionKey,
const std::string & connectionString = ""
) const;

Returns true if the session is active (i.e. not shut down). If connectionString is empty string, sessionKey must be a fully qualified session name as registered with the pool container.

const std::string & name
);

Removes a SessionPool.

### shutdown
