Class RuleLoader

public abstract class RuleLoader extends Object

Interface for classes which can dynamically load custom plugin rules associated with a user's plugin class.

Each plugin declaration has an associated RuleLoader instance, and that instance's addRules method is invoked each time the input xml specifies that an instance of that plugged-in class is to be created.

This is an abstract class rather than an interface in order to make it possible to enhance this class in future without breaking binary compatibility; it is possible to add methods to an abstract class, but not to an interface.

Since: 1.6

Method Detail

addRules

public abstract void addRules(Digester d, String path)
Configures the digester with custom rules for some plugged-in class.

This method is invoked when the start of an xml tag is encountered which maps to a PluginCreateRule. Any rules added here are removed from the digester when the end of that xml tag is encountered.
