Wrappers for object pointers returned from the JVM.
Structs
Auto-release wrapper for pointer-based generic arrays.
Auto-delete wrapper for local refs.
Auto-release wrapper for pointer-based primitive arrays.
A global JVM reference. These are “pinned” by the garbage collector and are
guaranteed to not get collected until released. Thus, this is allowed to
outlive the
JNIEnv that it came from and can be used in other threads.Lifetime’d representation of a
jobject that is an instance of the
ByteBuffer Java class. Just a JObject wrapped in a new class.Lifetime’d representation of a
jclass. Just a JObject wrapped in a new
class.Wrapper around
jfieldID that implements Send + Sync since method IDs
are valid across threads (not tied to a JNIEnv).Wrapper for JObjects that implement
java/util/List. Provides methods to get,
add, and remove elements.An iterator over the keys and values in a map.
Wrapper for JObjects that implement
java/util/Map. Provides methods to get
and set entries and a way to iterate over key/value pairs.An iterator over the keys and values in a map.
Wrapper around
jmethodID that implements Send + Sync since method IDs
are valid across threads (not tied to a JNIEnv).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.Wrapper around
jfieldID that implements Send + Sync since field IDs
are valid across threads (not tied to a JNIEnv).Wrapper around
jmethodID that implements Send + Sync since method IDs
are valid across threads (not tied to a JNIEnv).Lifetime’d representation of a
jstring. Just a JObject wrapped in a new
class.Lifetime’d representation of a
jthrowable. Just a JObject wrapped in a
new class.Enums
Rusty version of the JNI C
jvalue enum. Used in Java method call arguments
and returns.ReleaseMode
Traits
Trait to define type array access/release
