public interface Plugin

Interface for objects designed to be pluggable in Liquibase. Implementations of this class should be looked up via factories rather than instantiated directly to support the extension system.

The normal pattern for plugins is for PluginFactory implementations to return them.

Field Summary

Fields

Modifier and Type	Field and Description
static int	PRIORITY_DEFAULT Value to return from priority functions when the plugin is the standard implementation.
static int	PRIORITY_NOT_APPLICABLE Value to return from priority functions when the plugin is not applicable.
static int	PRIORITY_SPECIALIZED Value to return from priority functions when the plugin is a specialized, non-default implementation.
