SYNOPSIS

## PRELIMINARIES

use DiaColloDB::Compat;

##========================================================================

DESCRIPTION

DiaColloDB::Compat is a top-level convenience package for limited (read-only) backwards-compatible access to outdated DiaColloDB data structures and file formats. By convention, individual compatibility wrappers for a DiaColloDB release with version <= X.Y.Z reside in the namespace DiaColloDB::Compat::vX_Y_Z, where the "_Z" suffix is omitted if it consists only of zeroes.

Globals

Variable: @ISA

DiaColloDB::Compat inherits from DiaColloDB::Logger.

Utilities

usecompat

$bool = $that->usecompat($pkg);

Attempts to "use DiaColloDB::Compat::$pkg", throwing an error on failure.

nocompat

\&dummyMethodCode = $that->nocompat($methodName);

Wrapper-generator for subclasses which do not implement some API methods.
