Detailed Description

template<typename AttributeValueT = int>
class boost::sinks::syslog::custom_severity_mapping< AttributeValueT >

Customizable severity level mapping.

The class allows to setup a custom mapping between an attribute and Syslog severity levels. The mapping should be initialized similarly to the standard map container, by using indexing operator and assignment.

Member Function Documentation

mapped_type boost::sinks::basic_custom_mapping< level , AttributeValueT >::operator() ( record_view const &  rec) const
inlineinherited

Extraction operator.

Extracts the attribute value and attempts to map it onto the native value.

Parameters
recA log record to extract value from
Returns
A mapped value, if mapping was successful, or the default value if mapping did not succeed.
reference_proxy boost::sinks::basic_custom_mapping< level , AttributeValueT >::operator[] ( attribute_value_type const &  key)
inlineinherited

Insertion operator.

Parameters
keyAttribute value to be mapped
Returns
An object of unspecified type that allows to insert a new mapping through assignment. The key argument becomes the key attribute value, and the assigned value becomes the mapped native value.
