Detailed Description

Log record filter function wrapper.

Member Typedef Documentation

typedef bool boost::filter::result_type

Result type.

Constructor & Destructor Documentation

boost::filter::filter ( )

inline

Default constructor.

Creates a filter that always returns true.

Referenced by operator=().

boost::filter::filter ( filter const &  that )

inline

Copy constructor.

boost::filter::filter ( BOOST_RV_REF(filter)  that )

inline

Move constructor.

The moved-from filter is left in an unspecified state.

template<typename FunT >

boost::filter::filter ( FunT &&  fun )

inline

Initializing constructor.

Creates a filter which will invoke the specified function object.

Member Function Documentation

result_type boost::filter::operator() ( attribute_value_set const &  values ) const

inline

Filtering operator.

Parameters

values

Attribute values of the log record.

Returns

true if the log record passes the filter, false otherwise.

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

inline

Move assignment.

The moved-from filter is left in an unspecified state.

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

inline

Copy assignment.

template<typename FunT >

filter& boost::filter::operator= ( FunT const &  fun )

inline

Initializing assignment.

Sets the specified function object to the filter.

References filter().

void boost::filter::reset ( void  )

inline

Resets the filter to the default.

The default filter always returns true.

Referenced by boost::sinks::basic_sink_frontend::reset_filter().

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

inline

Swaps two filters.
