Struct uni_tmp_jni::objects::AutoPrimitiveArray

pub struct AutoPrimitiveArray<'a: 'b, 'b> { /* fields omitted */ }

Auto-release wrapper for pointer-based primitive arrays.

This wrapper is used to wrap pointers returned by get_primitive_array_critical.

These pointers normally need to be released manually, through a call to release_primitive_array_critical. This wrapper provides automatic pointer-based array release when it goes out of scope.

Implementations

impl<'a, 'b> AutoPrimitiveArray<'a, 'b>

pub fn new(
    env: &'b JNIEnv<'a>,
    obj: JObject<'a>,
    ptr: *mut c_void,
    mode: ReleaseMode,
    is_copy: bool
) -> Result<Self>

Creates a new auto-release wrapper for a pointer-based primitive array.

Once this wrapper goes out of scope, release_primitive_array_critical will be called on the object. While wrapped, the object can be accessed via the From impl.

pub fn as_ptr(&self) -> *mut c_void

Get a reference to the wrapped pointer

pub fn commit(&mut self)

Commits the result of the array, if it is a copy

pub fn is_copy(&self) -> bool

Indicates if the array is a copy or not

Trait Implementations

impl<'a, 'b> Drop for AutoPrimitiveArray<'a, 'b>

fn drop(&mut self)

Executes the destructor for this type.

impl<'a, '_> From<&'a AutoPrimitiveArray<'a, '_>> for *mut c_void

fn from(other: &'a AutoPrimitiveArray<'_, '_>) -> *mut c_void

Performs the conversion.
