public class PluginAssertionFailure extends RuntimeException
This class is intended to be used in assertion statements, similar to the way that java 1.4's native assertion mechanism is used. However there is a difference: when a java 1.4 assertion fails, an AssertionError is thrown, which is a subclass of Error; here, the PluginAssertionFailure class extends RuntimeException rather than Error.
This difference in design is because throwing Error objects is not good in a container-based architecture.
Example:
if ( impossibleCondition )
{
throw new PluginAssertionFailure( "internal error: impossible condition is true" );
}
Note that PluginAssertionFailure should not be thrown when user input is bad, or when code external to the Digester module passes invalid parameters to a plugins method. It should be used only in checks for problems which indicate internal bugs within the plugins module.
