Detailed Description

template<typename E>
class drain::SingleFlagger< E >

Abstract class, because getDict() returning Dictionary<std::string,E> still undefined.

Member Function Documentation

assign()

virtual void assign ( const std::string &  key )

inlineoverrideprotectedvirtual

Assign key. Expects a single key, not a combination of keys.

By definition, SingleFlagger contains a value that corresponds to a single key, at a time.

MultiFlagger::assign() supports setting several keys at once.

Implements FlaggerBase< E, E >.

getDict()

virtual const dict_t& getDict ( ) const

inlineoverridevirtual

Returns the static dictionary created for this value_t .

Notice that this function is non-static but returns a reference to a static dictionary. In C++ virtual functions must be non-static. This is nevertheless handy in templated design, for example.

Implements FlaggerBase< E, E >.
