Here is the call graph for this function:

filter()

Whoops\Exception\FrameCollection::filter

(

$callable

)

Filters frames using a callable, returns the same FrameCollection.

Parameters

callable

$callable

Returns

FrameCollection

    }

getArray()

Whoops\Exception\FrameCollection::getArray

(
