T Converter::Get ( const void *  dat, size_t  size  ) const

private

Converts the provided data block into a vector of boost::any or a string.

Template Parameters

T	Kind of data to be returned. This can either be boost::any objects or a string

Returns

A vector of the given template type containing the arguments. In case of failure an empty vector is returned.

Exceptions

std::runtime_error

if the conversion was not successfull
