Struct jni::objects::AutoArray

pub struct AutoArray<'a: 'b, 'b, T: TypeArray> { /* private fields */ }

Auto-release wrapper for pointer-based generic arrays.

This wrapper is used to wrap pointers returned by GetArrayElements. While wrapped, the object can be accessed via the From impl.

AutoArray provides automatic array release through a call to appropriate ReleaseArrayElements when it goes out of scope.

Implementations

impl<'a, 'b, T: TypeArray> AutoArray<'a, 'b, T>

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

Get a reference to the wrapped pointer

pub fn commit(&self) -> Result<()>

Commits the changes to the array, if it is a copy

pub fn discard(&mut self)

Don’t commit 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, T: TypeArray> Drop for AutoArray<'a, 'b, T>

fn drop(&mut self)

Executes the destructor for this type.

impl<'a, T: TypeArray> From<&'a AutoArray<'a, '_, T>> for *mut T

fn from(other: &'a AutoArray<'_, '_, T>) -> *mut T

Converts to this type from the input type.
