Struct jni::objects::JObject

#[repr(C)]
pub struct JObject<'a> { /* fields omitted */ }

Wrapper around sys::jobject that adds a lifetime. This prevents it from outliving the context in which it was acquired and getting GC'd out from under us. It matches C's representation of the raw pointer, so it can be used in any of the extern function argument positions that would take a jobject.

Most other types in the objects module deref to this, as they do in the C representation.

Methods

impl<'a> JObject<'a>

fn into_inner(self) -> jobject
