The `pvxs::Value` container class provides the means to interact with PVA data values.
|
|
|
|
.. code-block:: c++
|
|
|
|
#include <pvxs/data.h>
|
|
namespace pvxs { ... }
|
|
|
|
A `pvxs::Value` may be obtained via the remote peer (client or server),
|
|
or created locally. See `ntapi` or `typedefapi`.

Array fields
|
|
------------
|
|
|
|
Array fields are represented using the `pvxs::shared_array` container.
|
|
An example using `pvxs::nt::NTScalar`.
|
|
|
|
.. code-block:: c++
|
|
|
|
shared_array<double> arr({1.0, 2.0});
|
|
auto top = nt::NTScalar{TypeCode::Float64A}.create();
|
|
top["value"] = arr.freeze().castTo<void void>();
