You can use the signature function to produce JNI method signautures for methods; passing PyJnius JavaClass classes as return or argument types; provided here are annotations representing Java's primitive and array times. Methods can return just a standard primitive type: >>> signature(jint, ()) '()I' >>> s.signature(jvoid, [jint]) '(I)V' Or you can use autoclass proxies to specify Java classes for return types. >>> from jnius import autoclass >>> String = autoclass("java.lang.String") >>> signature(String, ()) '()Ljava/lang/String;' z0.0.1é)Ú JavaClass)Ú java_methodc@seZdZdZdS)Ú_JavaSignaturePrimitiveÚN)Ú__name__Ú __module__Ú __qualname__Ú_spec©r r ú.__Primitivez$ PyJnius signature for Java %s type N)rrrÚ_namer r ©ÚnameÚspecr r Ú __Primitive1srÚj)rr)rrrr r r Ú_MakeSignaturePrimitive0s rZbooleanÚZZbyteÚBÚcharÚCZdoubleÚDÚfloatÚFÚintÚIZlongÚJZshortÚSZvoidÚVcCsdt|ƒ}td|ƒS)zR Signature helper for identifying arrays of a given object or primitive type. ú[Zarray)Ú_jni_type_specr)Zof_typerr r r ÚJArrayEs r!cCst||ƒ}t|ƒS)zg Alternative version of @java_method that takes JavaClass objects to produce the method signature. )Ú signaturer)ÚreturnsÚtakesZsigr r r Úwith_signatureMs r%cCs6g}|D]}| t|ƒ¡qdd |¡dt|ƒS)zi Produces a JNI method signature, taking the provided arguments and returning the given return type. ú(rú))Úappendr Újoin)r#r$Z out_takesÚargr r r r"Usr"cCs,t|tƒrd|jdSt|tƒr(|jSdS)zÕ Produces a JNI type specification string for the given argument.
