package: org.yuanrong.call.

public class VoidInstanceFunctionHandler extends Handler#

Operation class that calls a Java class instance member function without a return value.

Note

The VoidInstanceFunctionHandler class is a handle to the member function of a class instance after creating a Java class instance without a return value; it is the return type of the interface InstanceHandler.function.

Users can use the invoke method of VoidInstanceFunctionHandler to call member functions of Java class instances without return values.

Interface description#

public VoidInstanceFunctionHandler(YRFuncVoid func, String instanceId, ApiType apiType)#

The constructor of VoidInstanceFunctionHandler.

  • Parameters:

    • func - Java function name, supports 0 ~ 5 parameters, no return value user function.

    • instanceId - Java function instance ID.

    • apiType - The enumeration class has two values: Function and Posix. It is used internally by openYuanrong to distinguish function types. The default is Function.

public void invoke(Object… args) throws YRException#

Member method of the VoidInstanceFunctionHandler class, used to call member functions of void class instances.

  • Parameters:

    • args - The input parameters required to call the specified method.

  • Throws:

    • YRException - Unified exception types thrown.

public VoidInstanceFunctionHandler options(InvokeOptions options)#

Member method of the VoidInstanceFunctionHandler class, used to dynamically modify the parameters of the called void function.

Config conf = new Config("FunctionURN", "ip", "ip", "", false);
YR.init(conf);

InvokeOptions invokeOptions = new InvokeOptions();
invokeOptions.addCustomExtensions("app_name", "myApp");
InstanceHandler instanceHandler = YR.instance(MyYRApp::new).invoke();
VoidInstanceFunctionHandler insFuncHandler = instanceHandler.function(MyYRApp::myVoidFunction).options(invokeOptions);
insFuncHandler.invoke();
YR.Finalize();

  • Parameters:

    • options - Function call options, used to specify functions such as calling resources.

  • Returns:
