Class FAWEConfigTransformer

java.lang.Object

eu.cloudnetservice.wrapper.transform.bukkit.FAWEConfigTransformer

All Implemented Interfaces:

ClassTransformer

@Internal
public final class FAWEConfigTransformer
extends Object
implements ClassTransformer

FAWEConfigTransformer relies on preview features of the Java platform:

• FAWEConfigTransformer refers to one or more preview APIs: ClassTransform.

Programs can only use FAWEConfigTransformer when preview features are enabled.

Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.

A transformer implementation that disables the setAccessible method in the FAWE Config on old FAWE versions. This is due to the fact that the method uses illegal reflection in the attempt to set a final field which is not possible anymore on newer java versions.

Method Details

provideClassTransform

@NonNull
public @NonNull ClassTransformPREVIEW provideClassTransform()

Specified by:

provideClassTransform in interface ClassTransformer

Returns:

the class transform to apply to the target class.

classTransformWillingness

@NonNull
public @NonNull ClassTransformer.TransformWillingness classTransformWillingness(@NonNull
 @NonNull String internalClassName)

Checks if this class transformer is willing to transform the class with the given internal name. If this method is not returning a rejection status, the ClassTransformer.provideClassTransform()^PREVIEW method is called and the transform gets applied to the target class.

Specified by:

Parameters:

internalClassName - the internal class name of the class being checked for transformation.
