Detailed Description

Collection of filterable objects for logging control.

Manages multiple filterable objects registered in the logger class. Provides the same API as filterable, and calling an API on filters will invoke that API on all owned filterable objects.

Acts as a composite filter, allowing multiple filtering criteria to be applied to log messages simultaneously.

Constructor & Destructor Documentation

filters()

template<typename... Es>

by::filters::filters ( const Es *... elems )

inlineexplicit

Constructs a filters object with multiple filterable elements.

This variadic template constructor allows convenient initialization of the filters object by adding multiple filterable instances.

Template Parameters

Es	Type of the filterable elements (must be convertible to filterable*).

Parameters

elems

Pointers to the filterable objects to add.

Member Function Documentation

add() [1/2]

void by::filters::add

(

const filterable &

new1

)

Adds a filterable object to the collection.

Parameters

new1	The filterable object to add. The filters object does not take ownership.

add() [2/2]

void by::filters::add

(

const filterable *

new1

)

Adds a filterable object to the collection.

Parameters

new1	Pointer to the filterable object to add. The filters object does not take ownership.

del()

void by::filters::del

(

)

Deletes all owned filterable objects and clears the collection.

Note

This method assumes ownership of the added filterable pointers and deletes them.

filt()

nbool by::filters::filt ( errLv::level lv, const std::string & tag ) const

virtual

Applies all contained filters to the log entry.

This method returns true if any of the contained filterable objects return true for the given log entry, indicating it should be filtered out.

Parameters

lv	The error level of the log entry.
tag	The tag associated with the log entry.

Returns

true if the log entry should be filtered out (blocked), false otherwise.

Implements by::filterable.
