Detailed Description

template<typename E, typename T = size_t>
class drain::MultiFlagger< E, T >

Note that if enum definition contains overlapping (combined) values, SingleFlagger may be sufficient. If arbitrary bit combinations should be supported, MultiFlagger must be used. Example {USER=1, GROUP=2, OTHER=4, ALL=USER|GROUP|OTHER}.

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

Constructor & Destructor Documentation

MultiFlagger()

MultiFlagger ( const dict_t &  dict, storage_t &  target, char  sep = ','  )

inline

Parameters

v	- linked variable

Member Function Documentation

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, size_t >.

set()

void set ( const V &...  args )

inline

Set bits, accepting numeric values or keys.

Starts with resetting the flags.

Template Parameters

T	– numeric values or strings

Member Data Documentation

dict

const dict_t& dict

protected

Given only a numeric/enum value,.

This should be called after assigning a string to & str() .
