NAME

SYNOPSIS

    my $pipe = Text::Pipe->new('List::First', code => { $_ < 7 });
    my $result = $pipe->filter('foo');

DESCRIPTION

METHODS

"clear_code"

    $obj->clear_code;
    

Clears the coderef.

"code"

    my $value = $obj->code;
    $obj->code($value);
    

A basic getter/setter method for the coderef. If called without an argument, it returns the value. If called with a single argument, it sets the value.

"code_clear"

Synonym for "clear_code()".

"filter"

If the input is an array reference, it passes each element to the code reference. The element will be in $_. Returns the first element for which the code reference returns a true value.

If the input is a single string, it just returns that string. This is semantically correct - if there is only one string, it has to be the first one as well.
