Get()

template<class ContainerType , typename std::enable_if< std::is_base_of< ArgFlagVal, typename ContainerType::value_type >::value >::type * = nullptr>

unsigned drama::gitarg::ArgFlags< ContainerType, >::Get ( const sds::Id &  Id, const unsigned  First = 1, unsigned  Last = 0, const bool  FailOnInvalid = true  )

inline

Get argument flag value set from an SDS structure.

The value (as returned by this method or GetVal() is zeroed on entry.

For each string flag name found in the argument structure, the corresponding flag value is or-ed into the resulting value. If the method throws, any valid values found before the throw will be set in a subsequent call to GetVal()

Parameters

Id	The SDS structure to read the flags from
First	Position of first argument to consider (1+)
Last	Position of last argument to consider. A value of 0 means to consider all found. Note - the first time we don't find any value (empty string or no such argument) we return immediately)
FailOnInvalid	Do we fail (throw) if a value is found which is not a flag value. Otherwise we ignore invalid values.

Returns

The flags which are set. Can also be returned later using GetVal();
