A high-level wrapper for JNI global object reference.

This is the base class for classes generated by jnigen.

Constructors

JObject.fromReference(JReference reference): Constructs a JObject with the underlying reference.

hashCode → int: The hash code for this object.
no setteroverride
isReleased → bool: no setter
jClass → JClass: Returns JClass corresponding to concrete class of this object.
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

as<T extends JObject>(JType<T> type, {bool releaseOriginal = false}) → T: Casts this object to another type.
isA<T extends JObject>(JType<T> type) → bool: Whether this object is of the given type ignoring the type parameters.
isInstanceOf(JClass jclass) → bool: Whether this object is of the type of the given jclass.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
release() → void: Releases the underlying reference.
releasedBy(Arena arena) → void: Registers this object to be released at the end of arena's lifetime.
toString() → String: A string representation of this object.
override
use<R>(R callback(T)) → R: Available on T, provided by the JObjectUseExtension extension
Applies callback on this object and then delete the underlying JNI reference, returning the result of callback.

type → const JType<JObject>: The type which includes information such as the signature of this class.
