Detailed Description

template<typename MappedT, typename AttributeValueT = int>
class boost::sinks::basic_direct_mapping< MappedT, AttributeValueT >

Straightforward mapping.

This type of mapping assumes that attribute with a particular name always provides values that map directly onto the native values. The mapping simply returns the extracted attribute value converted to the native value.
