[−][src]Trait uni_tmp_jni::descriptors::Desc

pub trait Desc<'a, T> {
    fn lookup(self, _: &JNIEnv<'a>) -> Result<T>;
}

Trait for things that can be looked up through the JNI via a descriptor. This will be something like the fully-qualified class name java/lang/String or a tuple containing a class descriptor, method name, and method signature. For convenience, this is also implemented for the concrete types themselves in addition to their descriptors.

Required methods

fn lookup(self, _: &JNIEnv<'a>) -> Result<T>

Look up the concrete type from the JVM.
