NAME

FP::Struct::Show -- automatic Show protocol implementation

SYNOPSIS

            

              
              
package FP_Struct_Show_Example::Foo {
    use FP::Struct ["a","b"],
      'FP::Struct::Show';
    _END_
}
FP_Struct_Show_Example::Foo::constructors->import;
use FP::Show;
is( show(Foo(1,1+1)),
    "Foo(1, 2)" );
# Whereas the default:
package FP_Struct_Show_Example::Bar {
    use FP::Struct ["a","b"];
    _END_
}
FP_Struct_Show_Example::Bar::constructors->import;
use FP::Show;
is( show(Bar(1, 2)),
    "bless(+{a => 1, b => 2}, 'FP_Struct_Show_Example::Bar')" );
            
          

DESCRIPTION

This class, when listed as a superclass of an FP::Struct, automatically implements the FP::Abstract::Show protocol (i.e. generates an `FP_Show_show` method that uses inspection specific to FP::Struct classes to get to know the public field values of the object it is being called on, and reconstructs a constructor call based on this information.) For the typical `FP::Struct` based class that don't have a preferred custom constructor this will be the right thing.
