Detailed Description

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

CRTP base that fills in the boilerplate of every cell-type descriptor.

Concrete descriptors inherit BaseCellTypeDescriptor<T> and provide the category() plus, when relevant, cell_from_json and to_json overrides.

Template Parameters

T	A CellLike cell type whose descriptor this is.

Constructor & Destructor Documentation

BaseCellTypeDescriptor()

template<CellLike T>

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

inlineexplicit

Construct with the given display info.

Parameters

info	Display info.

Member Function Documentation

base_to_json()

template<CellLike T>

json_t parcel::BaseCellTypeDescriptor< T >::base_to_json ( ) const

inlineprotected

Common JSON skeleton (kind, display_info, category) reused by overrides.

Returns

Base JSON object that derived to_json overrides extend.

to_json()

template<CellLike T>

json_t parcel::BaseCellTypeDescriptor< T >::to_json ( ) const

inlineoverridevirtual

Serialize the descriptor itself (kind + display info + category + extras).

Returns

JSON object describing this cell type.

Implements parcel::ICellTypeDescriptor.

Reimplemented in parcel::TypedListCellTypeDescriptor< T >, parcel::TypedMapCellTypeDescriptor< T >, parcel::StructCellTypeDescriptor< Derived, Payload >, and parcel::UnionCellTypeDescriptor< Ts >.
