      class IKeyManager

      interface IKeyManager
      Package:dji.v5.manager.interfaces
      Description:

      The class to manage the MSDK keys, MSDK provides a series of methods to access and control the parameters and behaviors of the hardware module which include the set and get method of a DJIKeyvalue. Also they include the listener and action of theDJIKeyvalue. You can use createKey method fromKeyToolsclass to create an instance of DJIKey more easily.

      Supported since MSDK 5.0.0

      method getValue
      @NonNull
      <Result> Result getValue(DJIKey<Result> key, @NonNull Result defaultValue)
      Package:dji.v5.manager.interfaces
      Description:

      Obtain the DJIValue value of the DJIKey synchronously, which is the value obtained from the MSDK cache. If the value cannot be read, the set defaultValue will be returned. To get the value asynchronously from the hardware device, please call getValue.

      Supported since MSDK 5.0.0

      Input Parameters:
      DJIKey<Result> keyDJIKey instance.
      @NonNull Result defaultValueWhen the MSDK cache value cannot be read, you want to return the default value.
      Return:
      <Result> ResultReturn DJIValue value.
