Detailed Description

template<CellLike T>
class parcel::SimpleCellTypeDescriptor< T >

Plain descriptor for cells in the Primitive category.

Used by PrimitiveCell<T>, ListCell, and MapCell — anywhere there is nothing more to expose beyond the base shape.

Template Parameters

T	A CellLike cell type.

Constructor & Destructor Documentation

SimpleCellTypeDescriptor()

template<CellLike T>

parcel::SimpleCellTypeDescriptor< T >::SimpleCellTypeDescriptor ( DisplayInfo  info )

inlineexplicit

Construct with the given display info.

Parameters

info	Display info.

Member Function Documentation

cell_from_json()

template<CellLike T>

cell_t parcel::SimpleCellTypeDescriptor< T >::cell_from_json ( const json_t &  j, const ParcelRegistry &  reg  ) const

inlineoverridevirtual

Construct a cell from JSON, dispatching to the concrete from_json.

Parameters

j	JSON object to deserialize.
reg	Registry used to resolve nested polymorphic cells.

Returns

Newly built cell handle.

Exceptions

std::runtime_error

on shape or kind mismatch.

Implements parcel::ICellTypeDescriptor.
