Struct 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 GetPrimitiveArrayCritical. While wrapped, the object can be accessed via the From impl.

AutoPrimitiveArray provides automatic array release through a call to ReleasePrimitiveArrayCritical when it goes out of scope.

Implementations

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

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

Get a reference to the wrapped pointer

pub fn discard(&mut self)

Don’t copy the changes to the array on release (if it is a copy). This has no effect if the array is not a copy. This method is useful to change the release mode of an array originally created with ReleaseMode::CopyBack.

pub fn is_copy(&self) -> bool

Indicates if the array is a copy or not

pub fn size(&self) -> Result<jsize>

Returns the array size

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.
