HTTP::Proxy::BodyFilter::simple - A class for creating simple filters use HTTP::Proxy::BodyFilter::simple; # a simple s/// filter my $filter = HTTP::Proxy::BodyFilter::simple->new( sub { ${ $_[1] } =~ s/foo/bar/g; } ); $proxy->push_filter( response => $filter ); HTTP::Proxy::BodyFilter::simple can create BodyFilter without going through the hassle of creating a full-fledged class. Simply pass a code reference to the "filter()" method of your filter to the constructor, and you'll get the adequate filter.

Constructor calling convention
The constructor can be called in several ways, which are shown in the synopsis: The code reference must conform to the standard filter() signature: sub filter { my ( $self, $dataref, $message, $protocol, $buffer ) = @_; ... } It is assumed to be the code for the "filter()" method. See HTTP::Proxy::BodyFilter.pm for more details about the "filter()" method. The name is the name of the method ("filter", "begin", "end") and the coderef is the method itself. See HTTP::Proxy::BodyFilter for the methods signatures. This filter "factory" defines the standard HTTP::Proxy::BodyFilter methods, but those are only, erm, "proxies" to the actual CODE references passed to the constructor. These "proxy" methods are: Two other methods are actually HTTP::Proxy::BodyFilter::simple methods, and are called automatically: Initalise the filter instance with the code references passed to the constructor. Return the actual code reference that will be run, and not the "proxy" methods. If called with any other name than "begin", "end" and "filter", calls UNIVERSAL::can() instead.
