Trait robusta_jni::convert::JavaValue

pub trait JavaValue<'env> {
    // Required methods
    fn autobox(self, env: &JNIEnv<'env>) -> JObject<'env>;
    fn unbox(s: JObject<'env>, env: &JNIEnv<'env>) -> Self;
}

A trait for types that are ffi-safe to use with JNI. It is implemented for primitives, JObject and jobject. Users that want automatic conversion should instead implement FromJavaValue, IntoJavaValue and/or TryFromJavaValue, TryIntoJavaValue

Required Methods

fn autobox(self, env: &JNIEnv<'env>) -> JObject<'env>

Convert instance to a JObject.

fn unbox(s: JObject<'env>, env: &JNIEnv<'env>) -> Self

Convert JObject to the implementing type.

Object Safety

This trait is not object safe.
