class AbstractSequence : public mindspore::abstract::AbstractBase

Class AbstractSequence describes the abstract value of a tuple or list.

Subclassed by mindspore::abstract::AbstractList, mindspore::abstract::AbstractTuple

Public Functions

explicit AbstractSequence(const AbstractBasePtrList &elements, const std::shared_ptr<AnfNodeWeakPtrList> &sequence_nodes)

Constructor of AbstractSequence.

Parameters

  • elements – [in] A list of abstracts.

  • sequence_nodes – [in] The nodes of tuple/list, usually are MakeTuple/MakeList CNodes or tuple/list ValueNodes.

~AbstractSequence() override = default

Destructor of AbstractSequence.

MS_DECLARE_PARENT (AbstractSequence, AbstractBase) TypePtrList ElementsType() const

Get the all of types.

Returns

A vector of types.

BaseShapePtrList ElementsShape() const

Returns

A vector of the broadened abstracts.

AbstractBasePtrList ElementsPartialBroaden() const

Broaden abstract with constraints, only when cond_func is true.

Returns

A pointer to the broadened abstract.

template<typename T>
ValuePtr ElementsBuildValue() const

Get real value by specific template.

Template Parameters

T – the class type of value.

Returns

A point to value.

template<typename T>
AbstractBasePtr ElementsJoin(const AbstractBasePtr &other)

Combine other abstract to the sequence of abstracts.

Template Parameters

T – param other’s class type.

Parameters

other – [in] The other abstract to be joined.

Returns

A pointer to the combined abstract.

Returns

A boolean, which indicates whether success.

inline const std::shared_ptr<AnfNodeWeakPtrList> &sequence_nodes() const
