=head1 NAME
|
|
|
|
JMX::Jmx4Perl::Agent::Jolokia::Verifier::ChecksumVerifier - Verifies a
|
|
checksum for a downloaded artifact.
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This verifier provides the base for simple checksum checking. It needs to be
|
|
subclassed to provide the proper extension (e.g. ".sha1") and creating of a
|
|
digester.
