Interface IGuildChannelContainer<C extends Channel>

All Known Subinterfaces:
Guild, JDA, ShardManager
All Known Implementing Classes:
DefaultShardManager
public interface IGuildChannelContainer<C extends Channel>
Provides various channel cache getters for Guild channels.

These getters only check the caches with the relevant scoping of the implementing type. For example, Guild returns channels that exist within the guild, whereas JDA or ShardManager returns any channels that exist within the shard.
If this is called on JDA or ShardManager, this may return null immediately after building, because the cache isn't initialized yet. To make sure the cache is initialized after building your JDA instance, you can use JDA.awaitReady().

For the most efficient usage, it is recommended to use CacheView getters such as getTextChannelCache(). List getters usually require making a snapshot copy of the underlying cache view, which may introduce an undesirable performance hit.

  • Method Details

    • getChannelCache

      @Nonnull ChannelCacheView<C> getChannelCache()
      Unified cache of all channels associated with this shard or guild.

      This ChannelCacheView stores all channels in individually typed maps based on ChannelType. You can use ChannelCacheView.getElementById(ChannelType, long) or ChannelCacheView.ofType(Class) to filter out more specific types.

      Returns:
      ChannelCacheView

    • getChannelById

      @Nullable default <T extends C> T getChannelById(@Nonnull Class<T> type, @Nonnull String id)
      Get a channel of the specified type by id.

      This will automatically check for all channel types and cast to the specified class. If a channel with the specified id does not exist, or exists but is not an instance of the provided class, this returns null.

      Type Parameters:
      T - The type argument for the class
      Parameters:
      type - Class of a channel type
      id - The snowflake id of the channel
      Returns:
      The casted channel, if it exists and is assignable to the provided class, or null
      Throws:
      IllegalArgumentException - If null is provided, or the id is not a valid snowflake

    • getChannelById

      @Nullable default <T extends C> T getChannelById(@Nonnull Class<T> type, long id)
      Get a channel of the specified type by id.

      This will automatically check for all channel types and cast to the specified class. If a channel with the specified id does not exist, or exists but is not an instance of the provided class, this returns null.

      Type Parameters:
      T - The type argument for the class
      Parameters:
      type - Class of a channel type
      id - The snowflake id of the channel
      Returns:
      The casted channel, if it exists and is assignable to the provided class, or null
      Throws:
      IllegalArgumentException - If null is provided

    • getGuildChannelById

      @Nullable default GuildChannel getGuildChannelById(@Nonnull String id)
      Get GuildChannel for the provided ID.

      This getter exists on any instance of IGuildChannelContainer and only checks the caches with the relevant scoping. For Guild, JDA, or ShardManager, this returns the relevant channel with respect to the cache within each of those objects. For a guild, this would mean it only returns channels within the same guild.
      If this is called on JDA or ShardManager, this may return null immediately after building, because the cache isn't initialized yet. To make sure the cache is initialized after building your JDA instance, you can use JDA.awaitReady().

      To get more specific channel types you can use one of the following:

      Parameters:
      id - The ID of the channel
      Returns:
      The GuildChannel or null
      Throws:
      IllegalArgumentException - If the provided ID is null
      NumberFormatException - If the provided ID is not a snowflake

    • getGuildChannelById

      If this is called on JDA or ShardManager, this may return null immediately after building, because the cache isn't initialized yet. To make sure the cache is initialized after building your JDA instance, you can use JDA.awaitReady().

      To get more specific channel types you can use one of the following:

      Parameters:
      id - The ID of the channel
      Returns:
      The GuildChannel or null

    • getGuildChannelById

      @Nullable default GuildChannel getGuildChannelById(@Nonnull ChannelType type, @Nonnull String id)

      If this is called on JDA or ShardManager, this may return null immediately after building, because the cache isn't initialized yet. To make sure the cache is initialized after building your JDA instance, you can use JDA.awaitReady().
      This is meant for systems that use a dynamic ChannelType and can profit from a simple function to get the channel instance.

      To get more specific channel types you can use one of the following:

      Parameters:
      type - The ChannelType
      id - The ID of the channel
