Enum DoubleArray 

pub enum DoubleArray {}

A PrimitiveArray implementation.

Trait Implementations

impl JniType for DoubleArray

fn static_with_jni_type<R>(callback: impl FnOnce(&CStr) -> R) -> R

impl PrimitiveArray<f64> for DoubleArray

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

Uses JNI New{Type}Array to create a new Java array containing “size” elements.

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

Uses JNI New{Type}Array + Set{Type}ArrayRegion to create a new Java array containing a copy of “elements”.

fn len(self: &Ref<'_, Self>) -> usize

Uses JNI GetArrayLength to get the length of the Java array.

fn get_region(self: &Ref<'_, Self>, start: usize, elements: &mut [jdouble])

Uses JNI Get{Type}ArrayRegion to read the contents of the Java array within [start .. start + elements.len()].

fn set_region(self: &Ref<'_, Self>, start: usize, elements: &[jdouble])

Uses JNI Set{Type}ArrayRegion to set the contents of the Java array within [start .. start + elements.len()].

fn is_empty(self: &Ref<'_, Self>) -> bool

Uses JNI GetArrayLength to get the length of the Java array, returns true if it is 0.

fn get_region_as_vec( self: &Ref<'_, Self>, range: impl RangeBounds<usize>, ) -> Vec<T>

Uses JNI GetArrayLength + Get{Type}ArrayRegion to read the contents of the Java array within given range into a new Vec.

fn as_vec(self: &Ref<'_, Self>) -> Vec<T>

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