java.lang.Object
com.abubusoft.kripton.androidx.livedata.KriptonXPagedLiveDataHandlerImpl<T>
Type Parameters:
T - The type of the live data
All Implemented Interfaces:
LiveDataHandler
public abstract class KriptonXPagedLiveDataHandlerImpl<T>
extends java.lang.Object
implements LiveDataHandler
A PLiveData class that can be invalidated and computed on demand.

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

  • Method Details

    • getLiveData

      @NonNull public PagedLiveData<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
