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 Typedef Documentation

typedef AttributeValueT boost::sinks::basic_custom_mapping< level , AttributeValueT >::attribute_value_type

inherited

Attribute contained value type.

typedef base_type::mapped_type boost::sinks::basic_custom_mapping< level , AttributeValueT >::mapped_type

inherited

Mapped value type.

typedef mapped_type boost::sinks::basic_mapping< level >::result_type

inherited

Result type.

Constructor & Destructor Documentation

template<typename AttributeValueT = int>

boost::sinks::syslog::custom_severity_mapping< AttributeValueT >::custom_severity_mapping ( attribute_name const &  name )

inlineexplicit

Constructor.

Parameters

name	Attribute name

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

rec	A 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

key	Attribute 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.
