DESCRIPTION

App::Ack::Filter implementations are responsible for filtering filenames to be searched.

METHODS

Creates a filter implementation, registered as $type. @args are provided as additional arguments to the implementation's constructor.

App::Ack:Filter->register_filter($type, $package)

Registers a filter implementation package $package under the name $type.

$filter->filter($resource)

Must be implemented by filter implementations. Returns true if the filter passes, false otherwise. This method must not alter the passed-in $resource object.

$filter->invert()

Returns a filter whose "filter" method returns the opposite of this filter.

$filter->is_inverted()

Returns true if this filter is an inverted filter; false otherwise.
