NAME ^

VM::EC2::Error - Object describing an error emitted by the Amazon API

SYNOPSIS ^

  use VM::EC2;

  $ec2      = VM::EC2->new(...);
  $instance = $ec2->describe_instance(-instance_id=>'invalid-name');
  die $ec2->error if $ec2->is_error;

DESCRIPTION ^

This object represents an error emitted by the Amazon API. VM::EC2 method calls may return undef under either of two conditions: the request may simply have no results that satisfy it (for example, asking to describe an instance whose ID does not exist), or an error occurred due to invalid parameters or communication problems.

As described in VM::EC2, the VM::EC2->is_error method returns true if the last method call resulted in an error, and VM::EC2->error returns the content of the error message.

METHODS ^

These object methods are supported:

 message -- the error message
 code    -- the error code

STRING OVERLOADING ^

When used in a string context, this object will interpolate the code and message into a single string in the format "Message [Code]".
