Detailed Description

Logging record view class.

The logging record encapsulates all information related to a single logging statement, in particular, attribute values view and the log message string. The view is immutable, it is implemented as a wrapper around a reference-counted implementation.

Constructor & Destructor Documentation

boost::record_view::record_view ( record_view const &  that )

inline

Default constructor.

Creates an empty record view that is equivalent to the invalid record handle.

Postcondition

!*this == true

Copy constructor

boost::record_view::record_view ( BOOST_RV_REF(record_view)  that )

inline

Move constructor.

Source record contents unspecified after the operation.

References boost::intrusive_ptr< T >::swap().

boost::record_view::~record_view ( )

inline

Destructor.

Destroys the record, releases any sinks and attribute values that were involved in processing this record.

Member Function Documentation

attribute_value_set const& boost::record_view::attribute_values ( ) const

inline

Returns

A reference to the set of attribute values attached to this record

Precondition

!!*this

Referenced by boost::abstract_ordering< FunT >::operator()(), boost::sinks::basic_direct_mapping< event_category, AttributeValueT >::operator()(), boost::value_visitor_invoker< channel_value_type, channel_fallback_policy >::operator()(), boost::sinks::basic_custom_mapping< event_category, AttributeValueT >::operator()(), and boost::value_extractor< T, FallbackPolicyT, TagT >::operator()().

bool boost::record_view::operator! ( ) const

inline

Conversion to an unspecified boolean type.

Returns

true, if the *this identifies a log record, false, if the *this is not valid

Inverted conversion to an unspecified boolean type

Returns

false, if the *this identifies a log record, true, if the *this is not valid

bool boost::record_view::operator!= ( record_view const &  that ) const

inline

Inequality comparison.

Parameters

that

Comparand

Returns

!(*this == that)

References operator==().

record_view& boost::record_view::operator= ( BOOST_COPY_ASSIGN_REF(record_view)  that )

inline

Copy assignment.

record_view& boost::record_view::operator= ( BOOST_RV_REF(record_view)  that )

inline

Move assignment.

Source record contents unspecified after the operation.

References boost::intrusive_ptr< T >::swap().

bool boost::record_view::operator== ( record_view const &  that ) const

inline

Equality comparison.

Parameters

that

Comparand

Returns

true if both *this and that identify the same log record or both do not identify any record, false otherwise.

Referenced by operator!=().

attribute_value_set::mapped_type boost::record_view::operator[] ( attribute_value_set::key_type  name ) const

inline

Attribute value lookup.

Parameters

name	Attribute name.

Returns

An attribute_value, non-empty if it is found, empty otherwise.

References boost::iostreams::gzip::flags::name.

template<typename DescriptorT , template< typename > class ActorT>

result_of::extract< typename expressions::attribute_keyword< DescriptorT, ActorT >::value_type, DescriptorT >::type boost::record_view::operator[] ( expressions::attribute_keyword< DescriptorT, ActorT > const &  keyword ) const

inline

Attribute value lookup.

Parameters

keyword

Attribute keyword.

Returns

A value_ref with extracted attribute value if it is found, empty value_ref otherwise.

void boost::record_view::reset ( void  )

inline

Resets the log record handle.

If there are no other handles left, the log record is closed and all resources referenced by the record are released.

Postcondition

!*this == true

References boost::intrusive_ptr< T >::reset().

void boost::record_view::swap ( record_view &  that )

inline

Swaps two handles.

Parameters

that	Another record to swap with Throws: Nothing

References boost::intrusive_ptr< T >::swap().
