NAME
PPI::Exception - The PPI exception base class
SYNOPSIS
use PPI::Exception;

PPI::Exception->new( message => 'something happened' )->throw;
PPI::Exception->throw( message => 'something happened' );
DESCRIPTION
All exceptions thrown from within PPI will be instances or derivations of this class.
METHODS
new $message | message => $message, ...
Constructs and returns a new PPI::Exception
object.
A message for the exception can be passed, either as a string or as message => $message
. The message is available via the message
method.
throw
If called on a PPI::Exception
object, throws the object. If called on the class name, uses the arguments to construct a PPI::Exception
and then throw it.
Each time the object is thrown, information from the Perl <caller(0)> call is saved and made available via the callers
method.
This method never returns.
message
Returns the exception message passed to the object's constructor, or a default message.
callers
Returns a listref, each element of which is a listref of caller(0)
information. The returned listref can be empty.
