Examples with AsyncInvocableWorkerResponseContext org.ballerinalang.bre.bvm.AsyncInvocableWorkerResponseContext used on opensource projects

Example 1 with AsyncInvocableWorkerResponseContext

use of org.ballerinalang.bre.bvm.AsyncInvocableWorkerResponseContext in project ballerina by ballerina-lang.

the class BLangFunctions method invokeNativeCallableAsync.

private static void invokeNativeCallableAsync(CallableUnitInfo callableUnitInfo, WorkerExecutionContext parentCtx, int[] argRegs, int[] retRegs) {
    WorkerData caleeSF = BLangVMUtils.createWorkerDataForLocal(callableUnitInfo.getDefaultWorkerInfo(), parentCtx, argRegs, callableUnitInfo.getParamTypes());
    Context nativeCtx = new NativeCallContext(parentCtx, callableUnitInfo, caleeSF);
    NativeCallableUnit nativeCallable = callableUnitInfo.getNativeCallableUnit();
    if (nativeCallable == null) {
        return;
    }
    AsyncInvocableWorkerResponseContext respCtx;
    if (nativeCallable.isBlocking()) {
        respCtx = BLangScheduler.executeBlockingNativeAsync(nativeCallable, nativeCtx);
    } else {
        respCtx = BLangScheduler.executeNonBlockingNativeAsync(nativeCallable, nativeCtx);
    }
    BLangVMUtils.populateWorkerDataWithValues(parentCtx.workerLocal, retRegs, new BValue[] { new BCallableFuture(callableUnitInfo.getName(), respCtx) }, new BType[] { BTypes.typeFuture });
}

Example 2 with AsyncInvocableWorkerResponseContext

use of org.ballerinalang.bre.bvm.AsyncInvocableWorkerResponseContext in project ballerina by ballerina-lang.

the class BLangFunctions method invokeNonNativeCallableAsync.

public static void invokeNonNativeCallableAsync(CallableUnitInfo callableUnitInfo, WorkerExecutionContext parentCtx, int[] argRegs, int[] retRegs) {
    WorkerSet workerSet = callableUnitInfo.getWorkerSet();
    int generalWorkersCount = workerSet.generalWorkers.length;

    WorkerData initWorkerLocalData = null;
    CodeAttributeInfo initWorkerCAI = null;

        initWorkerLocalData = executeInitWorker(parentCtx, argRegs, callableUnitInfo, workerSet.initWorker, wdi);
        if (initWorkerLocalData == null) {
            handleError(parentCtx);
            return;
        }
        initWorkerCAI = workerSet.initWorker.getCodeAttributeInfo();
    }
    List<WorkerExecutionContext> workerExecutionContexts = new ArrayList<>();
    /* execute all the workers in their own threads */
    for (int i = 0; i < generalWorkersCount; i++) {
        workerExecutionContexts.add(executeWorker(respCtx, parentCtx, argRegs, callableUnitInfo, workerSet.generalWorkers[i], wdi, initWorkerLocalData, initWorkerCAI, false));
    }
    /* set the worker execution contexts in the response context, so it can use them to do later
         * operations such as cancel */
    respCtx.setWorkerExecutionContexts(workerExecutionContexts);
    /* create the future encapsulating the worker response context, and set it as the return value
         * to the parent */
    BLangVMUtils.populateWorkerDataWithValues(parentCtx.workerLocal, retRegs, new BValue[] { new BCallableFuture(callableUnitInfo.getName(), respCtx) }, new BType[] { BTypes.typeFuture });
