Extension methods for typed object arrays.

Required Methods

fn typed_new_array<T: ObjectType, R: StrongRef>( &self, cls: &Class<R, T>, len: i32, ) -> Result<LocalObject<'_, Array<T>>, LocalObject<'_, JavaThrowable>>

Create a new object array.

fn typed_new_array_with_initial<T: ObjectType, R: StrongRef, IR: StrongRef>( &self, cls: &Class<R, T>, len: i32, initial: &Object<IR, T>, ) -> Result<LocalObject<'_, Array<T>>, LocalObject<'_, JavaThrowable>>

Create a new object array with initial value.

fn typed_get_array_element<T: ObjectType, R: StrongRef>( &self, arr: &Object<R, Array<T>>, index: i32, ) -> Result<Option<LocalObject<'_, T>>, LocalObject<'_, JavaThrowable>>

Get an element from object array.

fn typed_set_array_element<T: ObjectType, R: StrongRef>( &self, arr: &Object<R, Array<T>>, index: i32, value: Option<&Object<R, T>>, ) -> Result<(), LocalObject<'_, JavaThrowable>>

Set an element to object array.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
