===== Python/java method missing ======
Python class:<hederaDid.generated.PyFunction object at 0x7fb5258aab40>
Java method name:apply

class PyFunction(PythonJavaClass):
    __javainterfaces__ = ['java/util/function/Function']
    def __init__(self, fn):
        self.fn = fn
    @java_method('(Ljava/lang/Object;)Ljava/lang/Object;')
    def apply(self, tx):
        return self.fn(tx)
