AutoPrimitiveArray

Struct AutoPrimitiveArray 

Source
pub struct AutoPrimitiveArray<'a: 'b, 'b> { /* private fields */ }
Expand description

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§

Source§

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

Source

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.

Source

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

Get a reference to the wrapped pointer

Source

pub fn commit(&mut self)

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

Source

pub fn is_copy(&self) -> bool

Indicates if the array is a copy or not
