.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module provides an alternate error handling strategy for \f(CW\*(C`Net::Twitter\*(C'\fR.
Rather than throwing exceptions, \s-1API\s0 methods return \f(CW\*(C`undef\*(C'\fR and error
information is available through method calls on the \f(CW\*(C`Net::Twitter\*(C'\fR object.
.PP
This is the error handling strategy used when \f(CW\*(C`trait\*(C'\fR \f(CW\*(C`Legacy\*(C'\fR is used.  It
was the error handling strategy employed by \f(CW\*(C`Net::Twitter\*(C'\fR prior to version
3.00.
.SH "METHODS"
.IX Header "METHODS"
.IP "new" 4
.IX Item "new"
This method takes the same parameters as \*(L"new\*(R" in Net::Twitter.
.IP "get_error" 4
.IX Item "get_error"
Returns undef if there was no error or a \s-1HASH\s0 ref containing the Twitter error
response.  Occasionally, a Twitter \s-1API\s0 call results in an error with no error
content returned from Twitter.  When that occurs, get_error returns a simulated
error \s-1HASH\s0 ref.
.Sp
\&\s-1NOTE:\s0 Versions of \f(CW\*(C`Net::Twitter\*(C'\fR prior to 3.0 sometimes returned a string
rather than a \s-1HASH\s0 ref, on error.  This was a bug.  Always expect undef on
success and a \s-1HASH\s0 ref on error.
.IP "http_code" 4
.IX Item "http_code"
Returns the \s-1HTTP\s0 response code the most recent \s-1API\s0 method call if it ended in error.
.IP "http_message" 4
.IX Item "http_message"
Returns the \s-1HTTP\s0 message for the most recent \s-1API\s0 method call if it ended in error.
