Class KriptonXLiveDataHandlerImpl<T>

java.lang.Object
com.abubusoft.kripton.androidx.livedata.KriptonXLiveDataHandlerImpl<T>
Type Parameters:
T - The type of the live data
All Implemented Interfaces:
LiveDataHandler
public abstract class KriptonXLiveDataHandlerImpl<T> extends Object implements LiveDataHandler
A LiveData class that can be invalidated & computed when there are active observers.

It can be invalidated via invalidate(), which will result in a call to compute() if there are active observers (or when they start observing)

This is an internal class for now, might be public if we see the necessity.

  • Constructor Details

    • KriptonXLiveDataHandlerImpl

      public KriptonXLiveDataHandlerImpl()
      Creates a computable live data that computes values on the arch IO thread executor.

    • KriptonXLiveDataHandlerImpl

      public KriptonXLiveDataHandlerImpl(@NonNull Executor executor)
      Creates a computable live data that computes values on the specified executor.
      Parameters:
      executor - Executor that is used to compute new LiveData values.

  • Method Details

    • getLiveData

      @NonNull public KriptonXLiveData<T> getLiveData()
      Returns the LiveData managed by this class.
      Returns:
      A LiveData that is controlled by ComputableLiveData.

    • invalidate

      public void invalidate()
      Invalidates the LiveData.

      When there are active observers, this will trigger a call to compute().

      Specified by:
      invalidate in interface LiveDataHandler

    • compute

      @WorkerThread protected abstract T compute()
