Detailed Description

template<class T, class K = std::string>
class drain::Bank< T, K >

A single entry for each class D derived from T can be stored. The that \i base entry, any number of entries can be cloned. The cloned entries are of type D, yet accessible only through a reference of base class T .

Template Parameters

T	- value type (base type for cloning)
K	- key type

An entry may have several keys. Single-char keys (aliases) are provided by SuperBank

Member Typedef Documentation

key_set_t

typedef std::set<K> key_set_t

For enumerating keys.

Member Function Documentation

add()

D& add ( const K &  key )

inline

Adds class D as an internal instance.

For each class D, a single static instance is created.

It is allowed to adding a class repeatedly with different keys.

Changing static to external instance and vice versa causes a warning.

addExternal()

D& addExternal ( const D &  entry, const K &  key  )

inline

Adds class D using a copy constructor on an external instance.

For each class D, a single static instance is created.

It is allowed to adding a class repeatedly with different keys.

Changing static to external instance and vice versa causes a warning. Changing external instances is allowed.

resolve()

virtual const std::string& resolve ( const K &  key ) const

inlinevirtual

If K != std::string, this class must be derived and this function redefined.

Reimplemented in BankSuper< T >, and BankSuper< Command >.

set()

drain::ClonerBase<T>& set ( const std::string &  key, drain::ClonerBase< T > &  cloner  )

inlineprotected

Raises a warning if cloner is changed from external to internal, or vice versa.
