Interface ServerPluginValidator

All Known Implementing Classes:

AlertPluginValidator, BundlePluginValidator, ContentPluginValidator, GenericPluginValidator

public interface ServerPluginValidator

Validates that a given plugin descriptor is correct. This is usually used during a build of a server plugin, but can be used at runtime to confirm a descriptor is valid. This does more than just validating the XML descriptor parses (in fact, that is confirmed before this validator object is ever called). Instead, it detects if things such as classnames and configurations match was is to be expected. Implementors of this class must have a no-arg constructor so it can be found and created by ServerPluginValidatorUtil. The names of the implementor classes (if they are to be used by that utility) must match the name of the plugin type followed by "Validator" (e.g. "GenericPluginValidator" or "AlertPluginValidator"). They must be in a subpackage under the package where this interface is, where that subpackage is named for that plugin type (minus the word "Plugin" and all lowercase) such as ".generic" or ".alert". Note that when this validator is invoked, the plugin descriptor has already had its basics validated (that is, it is assured the descriptor XML is well-formed and validates against the XML schema, the plugin has been given a version, its plugin component class is valid and can be instantiated (if one was specified) among other things). Implementors of this validator class need only validate specific things that are unique to the specific plugin type for which this validator is used.
