void ObjectView<T> ()

Defined at line 15 of file ../../sdk/lib/fidl/cpp/wire/include/lib/fidl/cpp/wire/object_view.h

template <typename... Args>

void ObjectView<T> (AnyArena & allocator, Args &&... args)

Allocates an object using an arena.

This constructor creates the object using T(args...).

Defined at line 20 of file ../../sdk/lib/fidl/cpp/wire/include/lib/fidl/cpp/wire/object_view.h

void ObjectView<T> (AnyArena & allocator, T && obj)

These constructors are redundant with the above constructor, but are provided

anyway to help the compiler infer types in common cases. For example, one would

be able to write:

fidl::ObjectView(allocator, 42.0);

fidl::ObjectView(allocator, v);

instead of

fidl::ObjectView

<double

>(allocator, 42.0);

fidl::ObjectView

<fidl

::VectorView

<double

>>(allocator, v);

which is more verbose.

void ObjectView<T> (std::nullptr_t )

Initialize an ObjectView that contains null.

Defined at line 40 of file ../../sdk/lib/fidl/cpp/wire/include/lib/fidl/cpp/wire/object_view.h

ObjectView<T> FromExternal (T * from)

Constructs a fidl::ObjectView by unsafely borrowing other objects.

These methods are the only way to reference data which is not managed by an |Arena|.

Their usage is discouraged. The lifetime of the referenced object must be longer than the

lifetime of the created ObjectView.

For example:

Foo foo;

auto foo_view = fidl::ObjectView

<Foo

>::FromExternal(

&foo

);
