      • createPVScalar

        PVScalar createPVScalar​(PVScalar scalarToClone)
        Create an implementation of a scalar field by cloning an existing PVScalar. The new PVScalar will have the same value and auxInfo as the original.
        Parameters:
        scalarToClone - the PVScalar to clone
        Returns:
        the PVScalar implementation

      • createPVScalarArray

        PVScalarArray createPVScalarArray​(ScalarArray array)
        Create an implementation of an array field reusing the Array introspection interface.
        Parameters:
        array - the introspection interface
        Returns:
        the PVScalarArray implementation

      • createPVScalarArray

        PVScalarArray createPVScalarArray​(ScalarType elementType)
        Create an implementation for an array field. An Array introspection interface is created.
        Parameters:
        elementType - the element type
        Returns:
        the PVScalarArray implementation

      • createPVScalarArray

        PVScalarArray createPVScalarArray​(PVScalarArray arrayToClone)
        Create an implementation of an array field by cloning an existing PVArray. The new PVArray will have the same value and auxInfo as the original.
        Parameters:
        arrayToClone - the PVScalarArray to clone
        Returns:
        the PVScalarArray implementation
