NAME

Object::Tap - Tap into a series of method calls to alter an object

SYNOPSIS

Instead of writing -

  my $thing = My::Class->new(...);
  
  $thing->set_foo(1);

you can instead write -

  use Object::Tap;
  
  my $thing = My::Class->new(...)->$_tap(sub { $_[0]->set_foo(1) });

To realise why this might be useful, consider instead -

  My::App->new(...)->$_tap(...)->run;

where a variable is thereby not required at all.

You can also pass extra args -

  $obj->$_tap(sub { warn "Got arg: $_[1]" }, 'arg');

or use a method name instead of a sub ref -

  my $thing = My::Class->new(...)->$_tap(set_foo => 1);

For a 'real' example of how that might be used, one could create and initialize an HTML::TableExtract object in one go using -

  my $te = HTML::TableExtract->new->$_tap(parse => $html);
