VERSION

version 0.61

SYNOPSIS

  use Data::Object::Universal;

  my $object = Data::Object::Universal->new($scalar);

DESCRIPTION

Data::Object::Universal provides routines for operating on any Perl 5 data type.

METHODS

data

  # given $object

  $object->data; # original value

The data method returns the original and underlying value contained by the object. This method is an alias to the detract method.

defined

  # given $object

  $object->defined; # 1

The defined method returns true if the object represents a value that meets the criteria for being defined, otherwise it returns false. This method returns a Data::Object::Number object.

detract

  # given $object

  $object->detract; # original value

The detract method returns the original and underlying value contained by the object.

dump

  # given 0

  $object->dump; # 0

The dump method returns returns a string representation of the object. This method returns a Data::Object::String object.

eq

  # given $object

  $object->eq; # exception thrown

This method is a consumer requirement but has no function and is not implemented. This method will throw an exception if called.

ge

  # given $object

  $object->ge; # exception thrown

This method is a consumer requirement but has no function and is not implemented. This method will throw an exception if called.

gt

  # given $object

  $object->gt; # exception thrown

This method is a consumer requirement but has no function and is not implemented. This method will throw an exception if called.

le

  # given $object

  $object->le; # exception thrown

This method is a consumer requirement but has no function and is not implemented. This method will throw an exception if called.

lt

  # given $object

  $object->lt; # exception thrown

This method is a consumer requirement but has no function and is not implemented. This method will throw an exception if called.

methods

  # given $object

  $object->methods;

The methods method returns the list of methods attached to object. This method returns a Data::Object::Array object.

ne

  # given $object

  $object->ne; # exception thrown

This method is a consumer requirement but has no function and is not implemented. This method will throw an exception if called.

new

  # given $scalar

  my $object = Data::Object::Universal->new($scalar);

The new method expects a scalar reference and returns a new class instance.

print

  # given 0

  $object->print; # 0

The print method outputs the value represented by the object to STDOUT and returns true. This method returns a Data::Object::Number object.

roles

  # given $object

  $object->roles;

The roles method returns the list of roles attached to object. This method returns a Data::Object::Array object.

say

  # given 0

  $object->say; # '0\n'

The say method outputs the value represented by the object appended with a newline to STDOUT and returns true. This method returns a Data::Object::Number object.

throw

  # given $object

  $object->throw;

The throw method terminates the program using the core die keyword, passing the object to the Data::Object::Exception class as the named parameter object. If captured this method returns a Data::Object::Exception object.

type

  # given $object

  $object->type; # UNIVERSAL

The type method returns a string representing the internal data type object name. This method returns a Data::Object::String object.
