Constructors

JObject.fromReference(JReference reference)

Constructs a JObject with the underlying reference.

Properties

hashCode → int

The hash code for this object.

no setter, override

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 setter, inherited

Methods

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.

Operators

operator ==(Object other) → bool

The equality operator.

override

Constants

type → const JType<JObject>

The type which includes information such as the signature of this class.
