java.lang.Object

net.dv8tion.jda.bot.sharding.DefaultShardManagerBuilder

public class DefaultShardManagerBuilder
extends java.lang.Object

Used to create new instances of JDA's default ShardManager implementation.

Constructor Detail

DefaultShardManagerBuilder

public DefaultShardManagerBuilder()

Creates a completely empty DefaultShardManagerBuilder.
You need to set the token using setToken(String) before calling build().

Method Detail

setEnabledCacheFlags

public DefaultShardManagerBuilder setEnabledCacheFlags(java.util.EnumSet<CacheFlag> flags)

Flags used to enable parts of the JDA cache to reduce the runtime memory footprint.
It is highly recommended to use setDisabledCacheFlags(EnumSet) instead for backwards compatibility. We might add more flags in the future which you then effectively disable when updating and not changing your setting here.

Parameters:

flags - EnumSet containing the flags for cache services that should be enabled

Returns:

The DefaultShardManagerBuilder instance. Useful for chaining.

setDisabledCacheFlags

public DefaultShardManagerBuilder setDisabledCacheFlags(java.util.EnumSet<CacheFlag> flags)

Flags used to disable parts of the JDA cache to reduce the runtime memory footprint.
Shortcut for setEnabledCacheFlags(EnumSet.complementOf(flags))

Parameters:

flags - EnumSet containing the flags for cache services that should be disabled

Returns:

The DefaultShardManagerBuilder instance. Useful for chaining.

setSessionController

public DefaultShardManagerBuilder setSessionController(SessionController controller)

Sets the SessionController for the resulting ShardManager instance. This can be used to sync behaviour and state between shards of a bot and should be one and the same instance on all builders for the shards.

Parameters:

controller - The SessionController to use

Returns:

The DefaultShardManagerBuilder instance. Useful for chaining.

See Also:

SessionControllerAdapter

setContextMap

public DefaultShardManagerBuilder setContextMap(java.util.function.IntFunction<? extends java.util.concurrent.ConcurrentMap<java.lang.String,java.lang.String>> provider)

Sets the MDC mappings provider to use in JDA.
If sharding is enabled JDA will automatically add a jda.shard context with the format [SHARD_ID / TOTAL] where SHARD_ID and TOTAL are the shard configuration. Additionally it will provide context for the id via jda.shard.id and the total via jda.shard.total.

The manager will call this with a shardId and it is recommended to provide a different context map for each shard!
This automatically switches setContextEnabled(boolean) to true if the provided function is not null!

Parameters:

provider - The provider for modifiable context maps to use in JDA, or null to reset

Returns:

The DefaultShardManagerBuilder instance. Useful for chaining.

See Also:

MDC Javadoc

setContextEnabled

public DefaultShardManagerBuilder setContextEnabled(boolean enable)

Whether JDA should use a synchronized MDC context for all of its controlled threads.
Default: true

Parameters:

enable - True, if JDA should provide an MDC context map

Returns:

The DefaultShardManagerBuilder instance. Useful for chaining.

See Also:

MDC Javadoc, setContextMap(java.util.function.IntFunction)

setCompressionEnabled

public DefaultShardManagerBuilder setCompressionEnabled(boolean enable)

Enable stream-compression on the gateway connection, this will decrease the amount of used bandwidth for the running bot instance for the cost of a few extra cycles for decompression.
Default: true

We recommend to keep this enabled unless you have issues with the decompression
This mode might become obligatory in a future version, do not rely on this switch to stay.

Parameters:

enable - True, if the gateway connection should use compression

Returns:

The DefaultShardManagerBuilder instance. Useful for chaining.

public DefaultShardManagerBuilder setShards(java.util.Collection<java.lang.Integer> shardIds)

Sets the range of shards the DefaultShardManager should contain. This is useful if you want to split your shards between multiple JVMs or servers.

This does not have any effect if the total shard count is set to -1 (get recommended shards from discord).

Parameters:

shardIds - The list of shard ids

Returns:

The DefaultShardManagerBuilder instance. Useful for chaining.

Throws:

java.lang.IllegalArgumentException - If either minShardId is negative, maxShardId is lower than shardsTotal or minShardId is lower than or equal to maxShardId

setShardsTotal

public DefaultShardManagerBuilder setShardsTotal(int shardsTotal)

This will set the total amount of shards the DefaultShardManager should use.

If this is set to -1 JDA will automatically retrieve the recommended amount of shards from discord (default behavior).

Parameters:

shardsTotal - The number of overall shards or -1 if JDA should use the recommended amount from discord.

Returns:

The DefaultShardManagerBuilder instance. Useful for chaining.

setShards(int, int)

setToken

public DefaultShardManagerBuilder setToken(java.lang.String token)

Sets the token that will be used by the ShardManager instance to log in when build() is called.

To get a bot token:

1. Go to your Discord Applications
2. Create or select an already existing application
3. Verify that it has already been turned into a Bot. If you see the "Create a Bot User" button, click it.
4. Click the click to reveal link beside the Token label to show your Bot's token

Parameters:

token - The token of the account that you would like to login with.

Returns:

The DefaultShardManagerBuilder instance. Useful for chaining.

Throws:

java.lang.IllegalArgumentException - If the token is either null or empty

setUseShutdownNow

public DefaultShardManagerBuilder setUseShutdownNow(boolean useShutdownNow)

Whether the ShardManager should use JDA#shutdownNow() instead of JDA#shutdown() to shutdown it's shards.
Default: false

Parameters:

useShutdownNow - Whether the ShardManager should use JDA#shutdown() or not

Returns:

The DefaultShardManagerBuilder instance. Useful for chaining.

See Also:

JDA.shutdown(), JDA.shutdownNow()

setWebsocketFactory

public DefaultShardManagerBuilder setWebsocketFactory(com.neovisionaries.ws.client.WebSocketFactory factory)

Sets the WebSocketFactory that will be used by JDA's websocket client. This can be used to set things such as connection timeout and proxy.

Parameters:

factory - The new WebSocketFactory to use.

Returns:

The DefaultShardManagerBuilder instance. Useful for chaining.

build

public ShardManager build()
                   throws javax.security.auth.login.LoginException,
                          java.lang.IllegalArgumentException

Builds a new ShardManager instance and uses the provided token to start the login process.
The login process runs in a different thread, so while this will return immediately, ShardManager has not finished loading, thus many ShardManager methods have the chance to return incorrect information.
The main use of this method is to start the JDA connect process and do other things in parallel while startup is being performed like database connection or local resource loading.

Note that this method is async and as such will not block until all shards are started.

Returns:

A ShardManager instance that has started the login process. It is unknown as to whether or not loading has finished when this returns.

Throws:

javax.security.auth.login.LoginException - If the provided token is invalid.

java.lang.IllegalArgumentException - If the provided token is empty or null.
