NAME

PPI::Exception - The PPI exception base class

SYNOPSIS

use PPI::Exception;

my $e = PPI::Exception->new( 'something happened' );
$e->throw;

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.
