public <T> java.util.Optional<T> lookupRAOByType(java.lang.Class<T> raoType,
                                                 RuleActionContext context,
                                                 java.util.function.Predicate<T>... raoFilters)

Description copied from interface: RAOLookupService

Performs lookup for the RAO object identified by its type within provided RuleActionContext

Specified by:

lookupRAOByType in interface RAOLookupService

Type Parameters:

T - expected RAO object type

Parameters:

raoType - class type of RAO objects to look for

context - instance of RuleActionContext

raoFilters - optional set of Predicate to perform filtering against found RAO objects

Returns:

RAO object wrapped in Optional, or Optional.empty() in case no RAO object found that meets lookup and filtering criteria

lookupRAOObjectsByType

public <T> java.util.List<T> lookupRAOObjectsByType(java.lang.Class<T> raoType,
                                                    RuleActionContext context,

Specified by:

lookupRAOObjectsByType in interface RAOLookupService

Type Parameters:

T - expected RAO object type

Parameters:

raoType - class type of RAO objects to look for

context - instance of RuleActionContext

raoFilters - optional set of Predicate to perform filtering against found RAO objects

Returns:

list of found RAO objects that satisfy lookup criteria, or Collections.emptyList()

checkAndGetRuleContext

protected org.drools.core.spi.KnowledgeHelper checkAndGetRuleContext(RuleActionContext context)
