Struct jni::objects::JObject [−][src]
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.
