Class RuleRuntimeImpl

java.lang.Object

org.drools.jsr94.rules.RuleRuntimeImpl

All Implemented Interfaces:

Serializable, javax.rules.RuleRuntime

public class RuleRuntimeImpl
extends Object
implements javax.rules.RuleRuntime

The Drools implementation of the RuleRuntime interface which is the access point for runtime execution of RuleExecutionSets. It provides methods to create RuleSession implementation as well as methods to retrieve RuleExecutionSets that have been previously registered using the RuleAdministrator.

The RuleRuntime should be accessed through the RuleServiceProvider. An instance of the RuleRuntime can be retrieved by calling:

RuleServiceProvider ruleServiceProvider = RuleServiceProvider.newInstance();
RuleRuntime ruleRuntime = ruleServiceProvider.getRuleRuntime();

Note: the release method must be called on the RuleSession to clean up all resources used by the RuleSession.

createRuleSession in interface javax.rules.RuleRuntime

Parameters:

uri - the URI for the RuleExecutionSet

properties - additional properties used to create the RuleSession implementation.

ruleSessionType - the type of rule session to create.

Returns:

The created RuleSession.

Throws:

javax.rules.RuleSessionTypeUnsupportedException - if the ruleSessionType is not supported by Drools or the RuleExecutionSet

javax.rules.RuleExecutionSetNotFoundException - if the URI could not be resolved into a RuleExecutionSet

javax.rules.RuleSessionCreateException
