ABSTRACT

String Class for Perl 5

SYNOPSIS

  package main;

  use Data::Object::String;

  my $string = Data::Object::String->new('abcedfghi');

DESCRIPTION

This package provides methods for manipulating string data.

INHERITS

This package inherits behaviors from:

Data::Object::Kind

INTEGRATES

This package integrates behaviors from:

Data::Object::Role::Dumpable

Data::Object::Role::Proxyable

Data::Object::Role::Throwable

LIBRARIES

This package uses type constraints from:

Data::Object::Types

METHODS

This package implements the following methods:

  append() : Str

The append method appends arugments to the string using spaces.

append example #1
  my $string = Data::Object::String->new('firstname');
