class Base : public std::enable_shared_from_this<Base>

Base is a base class of many derived classes, which provides basic interfaces such as hash, and so on.

Subclassed by mindspore::AnfNode, mindspore::BaseRef, mindspore::Value, mindspore::abstract::AbstractBase, mindspore::abstract::BaseShape

Public Functions

constexpr Base() = default

The constructor of Base.

Returns: The instance of Base.

inline Base(const Base &other)

The copy constructor of Base.

Parameters: other – [in] Define another instance of Base.
Returns: The instance of Base.

virtual ~Base() = default: The destructor of Base.

inline virtual std::size_t hash() const

Get the hash value of this object.

Returns: The hash value.

inline virtual std::string ToString() const

Get the string representation of this object.

Returns: The string representation.

inline virtual void dump() const: Export the string representation to the standard output stream.

inline virtual std::string DumpText() const

Get the text representation of this object.

Returns: The text representation.

inline virtual bool IsFromTypeId(uint32_t tid) const

Judge whether this object is an instance of class with the given type id.

Parameters: tid – [in] Define a type id.
Returns: The result of the judgment.

inline virtual bool IsSameTypeId(uint32_t tid) const

Judge whether the type id of this object is same as the given type id.

Parameters: tid – [in] Define a type id.
Returns: The result of the judgment.

inline virtual std::string type_name() const

Get the type name of this object.

Returns: The type name.

inline virtual uint32_t tid() const

Get the type id of this object.

Returns: The type id.

template<typename T, typename std::enable_if<!is_shared_ptr<T>::value && std::is_base_of<Base, T>::value, T>::type* = nullptr> inline bool isa() const

Judge whether this object is an instance of a given class which is derived from Base.

Returns: The result of the judgment.

template<typename T, typename U = typename std::enable_if<is_shared_ptr<T>::value, typename T::element_type>::type> inline T cast()

Cast a shared_ptr of this object to a given class.

Returns: If success, a shared_ptr of the given class will be returned. Otherwise a nullptr will be returned.

Public Static Functions

static inline bool IsDerivedFrom(uint32_t tid) __attribute__((__always_inline__))

Judge whether this class is derived from class with the given type id.

Parameters: tid – [in] Define a type id.
Returns: The result of the judgment.

Public Static Attributes

static constexpr uint32_t kTypeId = ConstStringHash("Base"): The type id of this class.
