# This is basically a duplicate of Net::Twitter::Lite::Error, only without Moose. I
# considered creating a new Net-Twitter-Error distribution so that it could be
# shared by both Net::Twitter and Net::Twitter::Lite. But there's a strong
# argument for making Net::Twitter::Lite depend upon as few modules as
# possible.
=head1 NAME
Net::Twitter::Lite::Error - Encapsulates errors thrown by Net::Twitter::Lite
=head1 VERSION
version 0.12006
=head1 SYNOPSIS
use Net::Twitter::Lite;
my $nt = Net::Twitter::Lite->new;
my $r = eval { $nt->friends_timeline };
warn "$@\n" if $@;
=head1 DESCRIPTION
B<Net::Twitter::Lite::Error> encapsulates errors thrown by C<Net::Twitter::Lite>. A
C<Net::Twitter::Lite::Error> object will contain an C<HTTP::Response>, and a HASHREF
containing Twitter API error information if one was returned by Twitter.
=head1 METHODS
=over 4
=cut
=item new
Constructs an C<Net::Twitter::Lite::Error> object with an HTTP::Response and optionally
a Twitter error HASH ref. It takes HASH of arguments. Examples:
my $e = Net::Twitter::Lite::Error->new(http_response => $res, twitter_error => $te);
my $e = Net::Twitter::Lite::Error->new(http_response => $res);
=cut
sub new {
my ($class, %args) = @_;
return bless \%args, $class;
}
=item twitter_error
Get or set the encapsulated Twitter API error HASH ref.
=cut
sub twitter_error {
my $self = shift;
$self->{twitter_error} = shift if @_;
return $self->{twitter_error};
}
=item http_response
Get or set the encapsulated HTTP::Response instance.
=cut
sub http_response {
my $self = shift;
$self->{http_response} = shift if @_;
return $self->{http_response};
}
=item code
Returns the HTTP Status Code from the encapsulated HTTP::Response
=cut
sub code {
my $self = shift;
return exists $self->{http_response} && $self->{http_response}->code;
}
=item message
Returns the HTTP Status Message from the encapsulated HTTP::Response
=cut
sub message {
my $self = shift;
return exists $self->{http_response} && $self->{http_response}->message;
}
=item error
Returns an error message as a string. The message be the C<error> element of
the encapsulated Twitter API HASH ref, if there is one. Otherwise it will
return a string containing the HTTP Status Code and Message. If the
C<Net::Twitter::Lite::Error> instance does not contain either an HTTP::Response or a
Twitter Error HASH ref, or the HTTP::Response has no status code or message,
C<error> returns the string '[unknown]'.
A Net::Twitter::Lite::Error stringifies to the C<error> message.
=cut
sub error {
my $self = shift;
# We MUST stringyfy to something that evaluates to true, or testing $@ will fail!
exists $self->{twitter_error} && $self->{twitter_error}{error}
|| ( exists $self->{http_response}
&& ($self->code . ": " . $self->message )
)
|| '[unknown]';
}
