Detailed Description

An CommandNode that is triggered by a literal (i.e.

fixed) keyword.

An example would be a command like "ping", that is identified by its keyword.

Parameters

<S>	the type of the command source

Member Function Documentation

◆ addChild()

void com.mojang.brigadier.tree.CommandNode< S >.addChild ( final CommandNode< S > node )

inherited

Adds a new child node to this command node.

This will replace a command node with the same name, but there exist some bugs and some design decisions are not final as of now. Subsequently the exact behaviour in this case is not mandated. For a more detailed post about the problems, read this github issue.

You are not allowed to add children to commands with a getRedirect() target!

Parameters

node	the child command node to add

Exceptions

UnsupportedOperationException if you try to add a RootCommandNode to any other command node

◆ canUse()

boolean com.mojang.brigadier.tree.CommandNode< S >.canUse ( final S source )

inherited

Checks whether the given command source can use this command node.

This just checks the getRequirement() predicate, which could e.g. check for permissions.

Parameters

source the command source to check for

Returns: true if the given command source can use this command node

◆ createBuilder()

LiteralArgumentBuilder< S > com.mojang.brigadier.tree.LiteralCommandNode< S >.createBuilder ( )

Creates a builder for this command node.

Returns: a builder for this command node

Reimplemented from com.mojang.brigadier.tree.CommandNode< S >.

◆ equals()

boolean com.mojang.brigadier.tree.LiteralCommandNode< S >.equals ( final Object o )

Reimplemented from com.mojang.brigadier.tree.CommandNode< S >.

◆ findAmbiguities()

void com.mojang.brigadier.tree.CommandNode< S >.findAmbiguities ( final AmbiguityConsumer< S > consumer )

inherited

Tries to find ambiguities in the children of this command node and recurses down.

This can be used to detect whether multiple paths could be taken with a single input, which is not an ideal state for parsing commands. See CommandDispatcher#findAmbiguities for more information.

Parameters

consumer the AmbiguityConsumer to call when ambiguities are found

◆ getChild()

CommandNode< S > com.mojang.brigadier.tree.CommandNode< S >.getChild ( final String name )

inherited

Returns a child with the given getName.

Parameters

name	the name of the child command node

Returns: the child with that name or null if not found

◆ getChildren()

Collection< CommandNode< S > > com.mojang.brigadier.tree.CommandNode< S >.getChildren ( )

inherited

Returns all child command nodes.

Returns: all child command nodes

◆ getCommand()

Command< S > com.mojang.brigadier.tree.CommandNode< S >.getCommand ( )

inherited

Returns the command to execute when executing this command node.

Returns: the command to execute when executing this command node or null if not set

◆ getExamples()

Collection< String > com.mojang.brigadier.tree.LiteralCommandNode< S >.getExamples ( )

Returns example usages for this command node, which are used to find ambiguities.

Returns: some example usages for this command node, which are used to find ambiguities

See also: findAmbiguities

Reimplemented from com.mojang.brigadier.tree.CommandNode< S >.

◆ getLiteral()

String com.mojang.brigadier.tree.LiteralCommandNode< S >.getLiteral ( )

Returns the literal this command represents.

Returns: the literal this command represents

◆ getName()

String com.mojang.brigadier.tree.LiteralCommandNode< S >.getName ( )

Returns the name of this command node.

Returns: the name of this command node

Reimplemented from com.mojang.brigadier.tree.CommandNode< S >.

◆ getRedirect()

CommandNode< S > com.mojang.brigadier.tree.CommandNode< S >.getRedirect ( )

inherited

Returns the command node to redirect to.

Returns: the command node to redirect to or null if none

◆ getRedirectModifier()

RedirectModifier< S > com.mojang.brigadier.tree.CommandNode< S >.getRedirectModifier ( )

inherited

Returns the redirect modifier to apply when redirecting.

Returns: the redirect modifier to apply when redirecting or null if none

◆ getRelevantNodes()

Collection<? extends CommandNode< S > > com.mojang.brigadier.tree.CommandNode< S >.getRelevantNodes ( final StringReader input )

inherited

Returns all relevant command nodes for the input, so all nodes that are probably able to parse the input.

Parameters

input the input to check for

Returns: all relevant command nodes for the input, so all nodes that are probably able to parse the input

◆ getRequirement()

Predicate< S > com.mojang.brigadier.tree.CommandNode< S >.getRequirement ( )

inherited

Returns the requirement for this command node, that is used by canUse(Object).

Returns: the requirement for this command node, that is used by canUse(Object)

◆ getSortedKey()

String com.mojang.brigadier.tree.LiteralCommandNode< S >.getSortedKey ( )

protected

Returns a key for this command node, that is used for ordering the command nodes.

Returns: a key for this command node, that is used for ordering command nodes

Reimplemented from com.mojang.brigadier.tree.CommandNode< S >.

◆ getUsageText()

String com.mojang.brigadier.tree.LiteralCommandNode< S >.getUsageText ( )

Returns some usage text for this command node.

Returns: some usage text for this command node

Reimplemented from com.mojang.brigadier.tree.CommandNode< S >.

◆ hashCode()

int com.mojang.brigadier.tree.LiteralCommandNode< S >.hashCode ( )

Reimplemented from com.mojang.brigadier.tree.CommandNode< S >.

◆ isFork()

boolean com.mojang.brigadier.tree.CommandNode< S >.isFork ( )

inherited

Checks whether this command node forks.

See CommandDispatcher#execute(ParseResults) for an explanation of what it does.

Returns: true if this command node forks

◆ isValidInput()

boolean com.mojang.brigadier.tree.LiteralCommandNode< S >.isValidInput ( final String input )

Checks if the given input is valid for this command node, i.e.

if it is what the command expects.

This is used to find ambiguities.

Parameters

input the input to check

Returns: true if the given input is valid

See also: findAmbiguities

Reimplemented from com.mojang.brigadier.tree.CommandNode< S >.

◆ listSuggestions()

CompletableFuture< Suggestions > com.mojang.brigadier.tree.LiteralCommandNode< S >.listSuggestions	(	final CommandContext< S >	context,
		final SuggestionsBuilder	builder
	)

Lists suggestions for this command node, given the context and uses the passed SuggestionsBuilder to build them.

Parameters

context	the `CommandContext` to use for finding suggestions
builder	the suggestions builder

Returns: a completable future that might complete sometime in the future, as finding suggestions could involve I/O or other slow things

Exceptions

CommandSyntaxException if the command is not well formed

Reimplemented from com.mojang.brigadier.tree.CommandNode< S >.

◆ parse()

void com.mojang.brigadier.tree.LiteralCommandNode< S >.parse	(	final StringReader	reader,
		final CommandContextBuilder< S >	contextBuilder
	)		throws CommandSyntaxException

Tries to parse the command given by the reader and stores the results in the contextBuilder.

Parameters

reader	the reader to read from
contextBuilder	the context builder to store the results in

Exceptions

CommandSyntaxException if the input was malformed

Reimplemented from com.mojang.brigadier.tree.CommandNode< S >.
