Struct core_foundation::array::CFArray
[−]
[src]
pub struct CFArray { /* fields omitted */ }
A heterogeneous immutable array.
FIXME(pcwalton): Should be a newtype struct, but that fails due to a Rust compiler bug.
Methods
impl CFArray
[src]
fn from_CFTypes(elems: &[CFType]) -> CFArray
Creates a new CFArray
with the given elements, which must be CFType
objects.
fn iter<'a>(&'a self) -> CFArrayIterator<'a>
Iterates over the elements of this CFArray
.
Careful; the loop body must wrap the reference properly. Generally, when array elements are
Core Foundation objects (not always true), they need to be wrapped with
TCFType::wrap_under_get_rule()
. The safer iter_CFTypes
method will do this for you.
fn len(&self) -> CFIndex
fn get(&self, index: CFIndex) -> *const c_void
Trait Implementations
impl Drop for CFArray
[src]
impl TCFType<CFArrayRef> for CFArray
[src]
fn as_concrete_TypeRef(&self) -> CFArrayRef
Returns the object as its concrete TypeRef.
unsafe fn wrap_under_get_rule(reference: CFArrayRef) -> CFArray
Returns an instance of the object, wrapping the underlying CFTypeRef
subclass. Use this when following Core Foundation's "Get Rule". The reference count is bumped. Read more
fn as_CFTypeRef(&self) -> CFTypeRef
Returns the object as a raw CFTypeRef
. The reference count is not adjusted.
unsafe fn wrap_under_create_rule(obj: CFArrayRef) -> CFArray
Returns an instance of the object, wrapping the underlying CFTypeRef
subclass. Use this when following Core Foundation's "Create Rule". The reference count is not bumped. Read more
fn type_id() -> CFTypeID
Returns the type ID for this class.
fn as_CFType(&self) -> CFType
Returns the object as a wrapped CFType
. The reference count is incremented by one.
fn retain_count(&self) -> CFIndex
Returns the reference count of the object. It is unwise to do anything other than test whether the return value of this method is greater than zero. Read more
fn type_of(&self) -> CFTypeID
Returns the type ID of this object.
fn show(&self)
Writes a debugging version of this object on standard error.
fn instance_of<OtherConcreteTypeRef, OtherCFType: TCFType<OtherConcreteTypeRef>>(
&self
) -> bool
&self
) -> bool
Returns true if this value is an instance of another type.
