virtual void * data_to_dense_copy(void *to, const void *from) const =0
Creates a dense deep copy of data.
 
virtual bool dense() const =0
Indicate if the datatype is dense or not.
 
virtual size_t alignment() const =0
Returns the required alignment for a type.
 
virtual size_t buffersize() const =0
Computes the data size of a type, including potentially unused memory from a sparse type.
 
virtual Datatype_sptr slice(size_t start_index, size_t end_index) const
Access the type of the elements slice between the provided indices.
 
virtual std::pair< void *, Datatype_sptr > slice(size_t start_index, size_t end_index, void *data) const
Access the type and value of the elements slice between the provided indices.
 
virtual Datatype_sptr member(const char *name) const
Access the type of the member with the provided name.
 
virtual void destroy_data(void *ptr) const =0
Delete data whose type is described by the Datatype.
 
virtual void * data_from_dense_copy(void *to, const void *from) const =0
Creates a sparse deep copy of dense data.
 
Datatype(const Attributes_map &attributes={})
Creates a new datatype.
 
virtual std::pair< void *, Datatype_sptr > dereference(void *data) const
Access the type and value referenced by this.
 
virtual size_t datasize() const =0
Computes the data size of a type, excluding potentially unused memory from a sparse type.
 
virtual Datatype_sptr densify() const =0
Creates a new datatype as the dense copy of this one.
 
virtual Datatype_sptr dereference() const
Access the type referenced by this.
 
virtual Datatype_sptr index(size_t index) const
Access the type of the element at the provided index.
 
virtual bool simple() const =0
Tells if data can be copied as bytes (if type is dense) and doesn't need a destroyer.
 
virtual std::pair< void *, Datatype_sptr > member(const char *name, void *data) const
Access the type and value of the member with the provided name.
 
virtual std::pair< void *, Datatype_sptr > index(size_t index, void *data) const
Access the type and value of the element at the provided index.
 
virtual std::string debug_string() const =0
Returns the datatype yaml representation as a string.
