=head1 NAME
Net::Twitter::Error - A Net::Twitter exception object
=head1 SYNOPSIS
my $nt = Net::Twitter->new(username => $username, password => $password);
my $followers = eval { $nt->followers };
if ( my $err = $@ ) {
die $@ unless blessed $err and $err->isa('Net::Twitter::Error');
warn "HTTP Response Code: ", $err->code, "\n",
"HTTP Message......: ", $err->message, "\n",
"Twitter error.....: ", $err->error, "\n";
}
=head1 DESCRIPTION
B<Net::Twitter::Error> encapsulates the C<HTTP::Response> and Twitter
error HASH (if any) resulting from a failed API call.
=head1 METHODS
=over 4
=item new
Constructs a C<Net::Twitter::Error> object. It accepts the following parameters:
=over 4
=item http_response
An C<HTTP::Response> object, required.
=item twitter_error
The error returned by Twitter as a HASH ref. Optional, since some API errors do
not include a response from Twitter. They may, instead, be the result of network
timeouts, proxy errors, or some other problem that prevents an API response.
=back
=item twitter_error
Get or set the Twitter error HASH.
=item http_response
Get or set the C<HTTP::Response> object.
=item code
Returns the HTTP response code.
=item message
Returns the HTTP response message.
=item has_twitter_error
Returns true if the object contains a Twitter error HASH.
=item error
Returns the C<error> value from the C<twitter_error> HASH ref if there is one.
Otherwise, it returns the string "[unknown]".
