pub struct DoubleArray(_);

A PrimitiveArray implementation.

Trait Implementations

impl PrimitiveArray<f64> for DoubleArray

fn new<'env>(env: &'env Env, size: usize) -> Local<'env, Self>

Uses env.New{Type}Array to create a new java array containing "size" elements.

fn from<'env>(env: &'env Env, elements: &[jdouble]) -> Local<'env, Self>

Uses env.New{Type}Array + Set{Type}ArrayRegion to create a new java array containing a copy of "elements".

fn len(&self) -> usize

Uses env.GetArrayLength to get the length of the java array.

fn get_region(&self, start: usize, elements: &mut [jdouble])

Uses env.Get{Type}ArrayRegion to read the contents of the java array from [start .. start + elements.len())

fn set_region(&self, start: usize, elements: &[jdouble])

Uses env.Set{Type}ArrayRegion to set the contents of the java array from [start .. start + elements.len())

fn get_region_as_vec(&self, range: impl RangeBounds<usize>) -> Vec<T>

Uses env.GetArrayLength + env.Get{Type}ArrayRegion to read the contents of the java array from range into a new Vec.

fn as_vec(&self) -> Vec<T>

Uses env.GetArrayLength + env.Get{Type}ArrayRegion to read the contents of the entire java array into a new Vec.
