It pulls in the additional traits: C, C, C, and C. =head1 METHODS =over 4 =item new This method takes the same parameters as L. In addition, it also support the options: =over 4 =item arrayref_on_error When set to 1, on error, rather than returning undef, the API methods will return an empty ARRAY ref. Defaults to 0. =item twittervision When set to 1, enables the C call. Defaults to 0. =back =item clone Creates a shallow copy of the C object. This was useful, in legacy versions of C for handling concurrent requests (for instance with L). Since errors are wrapped in the C concurrent requests each needed their own object. C served that purpose. The recommended approach for concurrent requests is to use C's ability throw exceptions, now. =back =head1 SEE ALSO L =head1 AUTHOR Marc Mims =head1 LICENSE Copyright (c) 2016 Marc Mims This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself. =head1 DISCLAIMER OF WARRANTY BECAUSE THIS SOFTWARE IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE SOFTWARE, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
