NAME

       MouseX::NativeTraits::Str - Helper trait for Str attributes

SYNOPSIS

	 package MyHomePage;
	 use Mouse;

	 has 'text' => (
	     traits    => ['String'],
	     is        => 'rw',
	     isa       => 'Str',
	     default   => q{},
	     handles   => {
		 add_text     => 'append',
		 replace_text => 'replace',
	     },
	 );

	 my $page = MyHomePage->new();
	 $page->add_text("foo"); # same as $page->text($page->text . "foo");

DESCRIPTION

       This module provides a simple string attribute, to which mutating string operations can be applied more easily (no need to make an lvalue
       attribute metaclass or use temporary variables). Additional methods are provided for completion.

PROVIDED METHODS

       These methods are implemented in MouseX::NativeTraits::MethodProvider::Str. It is important to note that all those methods do in place
       modification of the value stored in the attribute.

       inc Increments the value stored in this slot using the magical string autoincrement operator. Note that Perl doesn't provide analogous
	   behavior in "--", so "dec" is not available.

       append($string)
	   Append a string, like ".=".

       prepend($string)
	   Prepend a string.

       replace($pattern, $replacement)
	   Performs a regexp substitution ("s" in perlop).  A code references will be accepted for the replacement, causing the regexp to be
	   modified with a single "e". "/smxi" can be applied using the "qr" operator.

       replace($pattern, $replacement)
	   Performs a regexp substitution ("s" in perlop) with the "g" flag.  A code references will be accepted for the replacement, causing the
	   regexp to be modified with a single "e". "/smxi" can be applied using the "qr" operator.

       match($pattern)
	   Like "replace" but without the replacement. Provided mostly for completeness.

       chop
	   "chop" in perlfunc

       chomp
	   "chomp" in perlfunc

       clear
	   Sets the string to the empty string (not the value passed to "default").

       length
	   "length" in perlfunc

       substr
	   "substr" in perlfunc. We go to some lengths to match the different functionality based on "substr"'s arity.

NAME

       MouseX::NativeTraits::HashRef - Helper trait for HashRef attributes

SYNOPSIS

	 package Stuff;
	 use Mouse;

	 has 'options' => (
	     traits    => ['Hash'],
	     is        => 'ro',
	     isa       => 'HashRef[Str]',
	     default   => sub { {} },
	     handles   => {
		 set_option	=> 'set',
		 get_option	=> 'get',
		 has_no_options => 'is_empty',
		 num_options	=> 'count',
		 delete_option	=> 'delete',
		 pairs		=> 'kv',
	     },
	 );

DESCRIPTION

       This module provides a Hash attribute which provides a number of hash-like operations.

PROVIDED METHODS

       These methods are implemented in MouseX::NativeTraits::MethodProvider::HashRef.

       get($key, $key2, $key3...)
	   Returns values from the hash.

	   In list context return a list of values in the hash for the given keys.  In scalar context returns the value for the last key
	   specified.

       set($key => $value, $key2 => $value2...)
	   Sets the elements in the hash to the given values.

       delete($key, $key2, $key3...)
	   Removes the elements with the given keys.

       exists($key)
	   Returns true if the given key is present in the hash.

       defined($key)
	   Returns true if the value of a given key is defined.

       keys
	   Returns the list of keys in the hash.

       sorted_keys
	   Returns the list of sorted keys in the hash.

       values
	   Returns the list of values in the hash.

       kv  Returns the key/value pairs in the hash as an array of array references.

	     for my $pair ( $object->options->pairs ) {
		 print "$pair->[0] = $pair->[1]
";
	     }

       elements
	   Returns the key/value pairs in the hash as a flattened list.

       clear
	   Resets the hash to an empty value, like "%hash = ()".

       count
	   Returns the number of elements in the hash. Also useful for not empty: "has_options => 'count'".

       is_empty
	   If the hash is populated, returns false. Otherwise, returns true.

       accessor
	   If passed one argument, returns the value of the specified key. If passed two arguments, sets the value of the specified key.
