void	init(Map<String,String> parameters) Inits the configuration.

Method Detail

init

void init(Map<String,String> parameters)
   throws MConfigurationException

Inits the configuration. This method should do as less operations as possible. This method should be called only once or throw an Exception.

Throws:

• Last change date / hour / milli
• ...

Implementations should compute hash at first call and store it in a cache.

Throws:

MConfigurationException

IRuleExecutionSetFactory getFactory()
                             throws MConfigurationException

Creates a new instance of a IRuleExecutionSetFactory, configured in parameters.

Throws:
