Description
|
|
-----------
|
|
|
|
The JavaClassWrapper singleton provides a way for the Godot application to send and receive data through the `Java Native Interface <https://developer.android.com/training/articles/perf-jni>`__ (JNI).
|
|
|
|
\ **Note:** This singleton is only available in Android builds.

var DateTimeFormatter = JavaClassWrapper.wrap("java.time.format.DateTimeFormatter")
|
|
|
|
var datetime = LocalDateTime.now()

var formatter = DateTimeFormatter.ofPattern("dd-MM-yyyy HH:mm:ss")

:ref:`JavaClass<class_JavaClass>` **wrap**\ (\ name\: :ref:`String<class_String>`\ ) :ref:`🔗<class_JavaClassWrapper_method_wrap>`
|
|

Wraps a class defined in Java, and returns it as a :ref:`JavaClass<class_JavaClass>` :ref:`Object<class_Object>` type that Godot can interact with.
|
|
|
