Struct ObjectArray 

pub struct ObjectArray<T: ReferenceType, E: ThrowableType>(/* private fields */);

A Java Array of reference types (classes, interfaces, other arrays, etc.)

Thread safety of avoiding race conditions is not guaranteed.

See also PrimitiveArray for arrays of reference types.

Implementations

impl<T: ReferenceType, E: ThrowableType> ObjectArray<T, E>

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

Uses JNI NewObjectArray to create a new Java object array.

pub fn iter<'a, 'env>( self: &'a Ref<'env, Self>, ) -> ObjectArrayIter<'a, 'env, T, E>

Iterates through object items of the array. See ObjectArrayIter.

pub fn new_from<'env>( env: Env<'env>, elements: impl ExactSizeIterator<Item = impl AsArg<T>>, ) -> Local<'env, Self>

Uses JNI NewObjectArray to create a new Java object array of the exact size, then sets its items with the iterator of JNI (null?) references.

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

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

pub fn get<'env>( self: &Ref<'env, Self>, index: usize, ) -> Result<Option<Local<'env, T>>, Local<'env, E>>

Gets a local reference of the object item at given index in the array. Returns None if it is null; returns an exception if the index is invalid.

XXX: Expose this via std::ops::Index.

pub fn set<'env>( self: &Ref<'env, Self>, index: usize, value: impl AsArg<T>, ) -> Result<(), Local<'env, E>>

Sets an element at the given index in the array. Returns an exception if the index is invalid.

XXX: I don’t think there’s a way to expose this via std::ops::IndexMut sadly?
