All Implemented Interfaces:

javax.rules.RuleSession, javax.rules.StatelessRuleSession

public class StatelessRuleSessionImpl

extends HaleyRuleSession

implements javax.rules.StatelessRuleSession

This class implements StatelessRuleSession interface. For Haley rules engine, there can be only one thread to access a StatelessRuleSession at any one time.

The StatelessRuleSession is a representation of a stateless rules engine session. A stateless rules engine session exposes a stateless rule execution API to an underlying rules engine.

Method Summary

java.util.List	executeRules(java.util.List objects, javax.rules.ObjectFilter filter) Executes the rules in the bound rule execution set using the supplied list of objects until no rule is executable anymore.
int	getType() Gets the type identifier for this RuleSession.

Method Detail

executeRules

public java.util.List executeRules(java.util.List objects)
                            throws javax.rules.InvalidRuleSessionException

Executes the rules in the bound rule execution set using the supplied list of objects until no rule is executable anymore. A list is returned over all objects created by the executed rules that pass the default RuleExecutionSet ObjectFilter(if present)

Specified by:

executeRules in interface javax.rules.StatelessRuleSession

Parameters:

objects - the objects ued to execute rules

Returns:

a List over all objects created by the executed rules

Throws:

javax.rules.InvalidRuleSessionException - on illegal rule session state

executeRules

public java.util.List executeRules(java.util.List objects,
                                   javax.rules.ObjectFilter filter)
                            throws javax.rules.InvalidRuleSessionException

Executes the rules in the bound rule execution set using the supplied list of objects until no rule is executable anymore. An iterator is returned over all objects created by the executed rules and filtered with the supplied object filter

Specified by:

executeRules in interface javax.rules.StatelessRuleSession

Parameters:

objects - the objects used to execute rules

filter - the object filter

Returns:

List

Throws:

javax.rules.InvalidRuleSessionException - on illegal rule session state

getType

public int getType()
            throws javax.rules.InvalidRuleSessionException

Gets the type identifier for this RuleSession. The type identifiers are defined in the RuleRuntime interface

Specified by:

getType in interface javax.rules.RuleSession

Overrides:

getType in class HaleyRuleSession

Returns:

int the stateless rule session type

Throws:

javax.rules.InvalidRuleSessionException - on illegal rule session state
