From 32d2606a6544961ecd8766ea445c729c301ed14f Mon Sep 17 00:00:00 2001 From: Profpatsch Date: Sat, 20 Jan 2024 22:26:24 +0100 Subject: [PATCH] BaseDescriptionFragment: Assert member is initialized `streamInfo` and `channelInfo` have to be initialized, since the only way to construct the class it to pass them. So we can remove the null check boilerplate and make some of the accessors `NonNull`. --- .../detail/BaseDescriptionFragment.java | 26 +++++++-------- .../fragments/detail/DescriptionFragment.java | 26 +++------------ .../list/channel/ChannelAboutFragment.java | 33 +++++++------------ 3 files changed, 27 insertions(+), 58 deletions(-) diff --git a/app/src/main/java/org/schabi/newpipe/fragments/detail/BaseDescriptionFragment.java b/app/src/main/java/org/schabi/newpipe/fragments/detail/BaseDescriptionFragment.java index e3bdc6592..4789b02e6 100644 --- a/app/src/main/java/org/schabi/newpipe/fragments/detail/BaseDescriptionFragment.java +++ b/app/src/main/java/org/schabi/newpipe/fragments/detail/BaseDescriptionFragment.java @@ -64,7 +64,7 @@ public abstract class BaseDescriptionFragment extends BaseFragment { /** * Get the description to display. - * @return description object + * @return description object, if available */ @Nullable protected abstract Description getDescription(); @@ -73,7 +73,7 @@ public abstract class BaseDescriptionFragment extends BaseFragment { * Get the streaming service.
