Trait Implementations

impl Class for ByteBuffer

const PATH: &'static str = "java/nio/ByteBuffer"

The fully qualified java class path (slash-separated)

impl Object for ByteBuffer

fn upcast<'a, 'e>(_: &'a mut Env<'e>, jobj: Object) -> Self

Try to interpret an object as Self

fn downcast<'a, 'e>(self, _: &'a mut Env<'e>) -> Object

Create an object reference from self

fn downcast_ref<'a, 'e>(&'a self, e: &'a mut Env<'e>) -> Object

Create an object reference from &self

fn upcast_value_ref<'e>(e: &mut Env<'e>, jv: JValue<'e, '_>) -> Self

where Self: Sized,

Try to interpret a JValue as Self

fn upcast_value<'e>(e: &mut Env<'e>, jv: JValueOwned<'e>) -> Self

where Self: Sized,

Try to interpret a JValueOwned as Self

fn downcast_value<'e>(self, e: &mut Env<'e>) -> JValueOwned<'e>

where Self: Sized,

Create a JValueOwned from self

fn yield_to_java(&self, e: &mut Env<'_>) -> jobject

Use this to yield ownership of a java::lang::Object to the JVM, for example when returning a jobject from a native function.
