execute

public int execute(CommandFunction function,
 ServerCommandSource source)

Executes a function.

This is same as calling execute(function, source, null).

Parameters:

function - the function

source - the command source to execute with

Returns:

the command output value

• execute(CommandFunction, ServerCommandSource, Tracer)

named	execute	Lnet/minecraft/server/function/CommandFunctionManager;execute(Lnet/minecraft/server/function/CommandFunction;Lnet/minecraft/server/command/ServerCommandSource;)I

execute

public int execute(CommandFunction function,
 ServerCommandSource source,
 @Nullable
 @Nullable CommandFunctionManager.Tracer tracer)

Executes a function. This may have two cases: new or recursive.

In a new execution, the execution == null, and a custom tracer can be specified. The return value indicates the number of commands and nested functions ran.

In a recursive execution, execution != null. It is required that tracer == null, or the execution reports an error and is skipped. The return value is 0.

Parameters:

function - the function

source - the command source to execute with

tracer - a tracer for a non-recursive function execution

Returns:

a non-zero value for a new execution, or 0 for a recursive execution

setFunctions

public void setFunctions(FunctionLoader loader)

Sets the functions that this command function manager will use in executions.

Parameters:

loader - the new loader functions will be taken from

getScheduledCommandSource

public ServerCommandSource getScheduledCommandSource()

Returns the command source to execute scheduled functions. Scheduled functions are those from the /schedule command and those from the minecraft:tick tag.

This command source has permission level 2 and is silent compared to the server's command source.

Returns:

the command source to execute scheduled functions
