OpModeManager

package com.skeletonarmy.marrow

Overview

OpModeManager provides a simple interface for accessing the internal OpMode manager. It allows your code to read the current OpMode, robot state, hardware map, telemetry, and register lifecycle listeners - without direct access to the SDK internals.

This is useful when you need to interact with OpMode-level information from subsystems or utilities without manually passing references around.

Do not access the current OpMode before it is initialized. The hardware map may also change during initialization, so avoid relying on or caching it early.

Usage

getManager()

Returns the active OpModeManagerImpl instance.

OpModeManagerImpl manager = OpModeManager.getManager();

---

getActiveOpMode()

Returns the currently running OpMode, or null if none is running.

OpMode active = OpModeManager.getActiveOpMode();

---

getActiveOpModeName()

Returns the name of the active OpMode.

String name = OpModeManager.getActiveOpModeName();

---

getRobotState()

Returns the current RobotState enum (e.g., INIT, RUNNING, STOPPED).

RobotState state = OpModeManager.getRobotState();

---

getHardwareMap()

Returns the active HardwareMap.

Useful when you need hardware access outside your OpMode.

HardwareMap hardwareMap = OpModeManager.getHardwareMap();

---

getTelemetry()

Returns the active Telemetry.

Useful when you need to debug things outside your OpMode.

Telemetry telemetry = OpModeManager.getTelemetry();

---

registerListener(listener)

Registers a listener for OpMode lifecycle changes.

The listener receives callbacks such as:

• onOpModePreInit

• onOpModePreStart

• onOpModePostStop

Returns the active OpMode at the time of registration.

OpModeManager.registerListener(myListener);

---

unregisterListener(listener)

Removes a previously registered listener.

OpModeManager.unregisterListener(myListener);
