NAME

SYNOPSIS

    package Text::Pipe::My::Segment;

    use base 'Text::Pipe::Base';

    sub filter {
        # blah
    }

DESCRIPTION

It also overloads the "|" operator so you can create stackable pipes like this:

    my $stackable_pipe = $pipe1 | $pipe2 | $pipe3;

METHODS

"new"

    my $obj = Text::Pipe::Base->new;
    my $obj = Text::Pipe::Base->new(%args);
    

Creates and returns a new object. The constructor will accept as arguments a list of pairs, from component name to initial value. For each pair, the named component is initialized by calling the method of the same name with the given value. If called with a single hash reference, it is dereferenced and its key/value pairs are set as described before.

"bit_or"

This subroutine implements the pipe stacking that is invoked by using the "|" operator, as in:

    my $stackable_pipe = $pipe1 | $pipe2 | $pipe3;
    

"filter"

Can filter a single string or an reference to an array of strings. Each string is filtered using "filter_single()".

"filter_single"

Filters a single string. In this base class this method just returns the input string unaltered.

"init"

This method is called by the constructor and passed the object so it can be initialized. In this class the method is empty, but it exists so that subclasses can override this method and call "SUPER::init()".
