	   use WebService::GData::Error;

	   #create an error object that	you can	throw by dying...
	   my $error = new WebService::GData::Error(401,'Unauthorized');

	   }

DESCRIPTION
       inherits	from WebService::GData.

       This package can	parse error response from Google APIs service. You can
       also create your	own basic error.  All WebService::GData::* classes die
       a WebService::GData::Error object when something	goes wrong.  You
       should use an eval {}; block to catch the error.

       Example:

	   use WebService::GData::Base;

	   my $base = new WebService::GData::Base();

	   eval	{
	       $base->get($url);
	   };

	   #$error is a	WebService::GData::Error;

	   if(my $error=$@){
	       #error->code,$error->content, $error->errors
	   }

   CONSTRUCTOR
       new

	   Create a WebService::GData::Error instance.	Will parse the
	   contents that you can access	via the	errors() method	of the
	   instance.

	   Parameters

	   "code:*" - This could be an http status or a	short string
	   error_code.
	   "content:Scalar" - The string can be	a Google xml error response,
	   in which case, it will get parsed.

	   Returns

	   WebService::GData::Error

	   Example:

	       use WebService::GData::Error;

	       #create an error	object that you	can throw by dying...
	       my $error = new WebService::GData::Error(401,'Unauthorized');

   GET METHODS
       code

       Get back	the error code.

       Parameters

       "none"

       Returns

       "code:Scalar"

       Example:

	   use WebService::GData::Error;

	   #create an error object that	you can	throw by dying...
	   my $error = new WebService::GData::Error(401,'Unauthorized');
	      $error->code;#401

       content

	   Get back the	raw content of the error.

	   When	getting	an error from querying one of Google data services,
	   you will get	a raw xml response containing possible errors.	In
	   such	case,you should	loop through the result	by using the errors()
	   instance which send back WebService::GData::Error::Entry.

	   Parameters

	   "none"

	   Returns

	   "content:Scalar"

	   Example:

	       use WebService::GData::Error;

	       #create an error	object that you	can throw by dying...
	       my $error = new WebService::GData::Error(401,'Unauthorized');
		  $error->content;#Unauthorized

       errors

	   Get back a reference	array filled with
	   WebService::GData::Error::Entry.  When getting an error from
	   querying one	of Google data services, you will get an xml response
	   containing possible errors.	In such	a case,you should loop through
	   the result of errors.  Errors always	send back a reference array
	   (even if there is no	error).

	   Parameters

	   "none"

	   Returns

	   WebService::GData::Error::Entry:ArrayRef

	   Example:

	       my @errors = $error->errors;#send back WebService::GData::Error::Entry objects

	       foreach my $error (@{$error->errors}){
		   print $error->code;
		   print $error->internalreason;
		   print $error->domain;
		   print $error->location->{type};#this	is just	a hash
		   print $error->location->{content};#this is just a hash
	       }
