Method Detail

removeHandler

public static void removeHandler(io.netty.channel.ChannelPipeline pipeline,
                                 String handler)

This method is used in Addons.
Most addons can be removed once the player associated to the channel has been logged in, but they should also be removed once the inject is removed. Because of how Netty works it will throw an exception and we don't want that. This method removes those handlers safely.

Parameters:

pipeline - the pipeline

handler - the name of the handler to remove

readProperties

public static Properties readProperties(String resourceFile)

Reads a properties resource file

Parameters:

resourceFile - the resource file to read

Returns:

the properties file if the resource exists, otherwise null

Throws:

AssertionError - if something went wrong while readin the resource file

getLocale

public static String getLocale(Locale locale)

getJavaUuid

public static UUID getJavaUuid(long xuid)

getJavaUuid

public static UUID getJavaUuid(String xuid)

isUniquePrefix

public static boolean isUniquePrefix(String prefix)

isValidDatabaseName

public static boolean isValidDatabaseName(String databaseName)

getStackTrace

public static String getStackTrace(Throwable throwable)

failedFuture

public static <U> CompletableFuture<U> failedFuture(Throwable ex)

Returns a new CompletableFuture that is already completed exceptionally with the given exception.

Type Parameters:

U - the type of the value

Parameters:

ex - the exception

Returns:

the exceptionally completed CompletableFuture

getGeneratedClassesForAnnotation

public static Set<Class<?>> getGeneratedClassesForAnnotation(Class<? extends Annotation> annotationClass)

Returns a set of all the classes that are annotated by a given annotation. Keep in mind that these are from a set of generated annotations generated at compile time by the annotation processor, meaning that arbitrary annotations cannot be passed into this method and expected to get a set of classes back.

Parameters:

annotationClass - the annotation class

Returns:

a set of all the classes annotated by the given annotation

getGeneratedClassesForAnnotation

public static Set<Class<?>> getGeneratedClassesForAnnotation(String input)

Returns a set of all the classes that are annotated by a given annotation. Keep in mind that these are from a set of generated annotations generated at compile time by the annotation processor, meaning that arbitrary annotations cannot be passed into this method and expected to have a set of classes returned back.

Parameters:

input - the fully qualified name of the annotation

Returns:

a set of all the classes annotated by the given annotation
