Class TransactionLockInterceptor

  • All Implemented Interfaces:
    org.drools.commands.ChainableRunner, org.drools.commands.InternalLocalRunner, org.kie.api.runtime.CommandExecutor, org.kie.api.runtime.ExecutableRunner<org.kie.api.runtime.RequestContext>
    public class TransactionLockInterceptor
extends org.drools.commands.impl.AbstractInterceptor
    ExecutableInterceptor that will lock underlying Runner until transaction completion. In case there is no transaction active lock is released directly. By default, interceptor is disabled and needs to be explicitly enabled in one of two ways:
    • using system property named org.kie.tx.lock.enabled that must be set to true
    • using environment entry named TRANSACTION_LOCK_ENABLED that must be set to true
