Detailed Description

an Array_datatype is a Datatype that represents an array: i.e storage of multiple elements of the same type continuously in memory.

Constructor & Destructor Documentation

◆ Array_datatype() [1/2]

PDI::Array_datatype::Array_datatype	(	Datatype_uptr	subtype,
		size_t	size,
		size_t	start,
		size_t	subsize
	)

Construct a new partially filled Array_datatype.

Parameters

[in]	subtype	the type of the elements contained in the array
	size	the number of elements the array can store
	start	the id of the first actual element of the array
	subsize	the number of actual elements in the array

◆ Array_datatype() [2/2]

PDI::Array_datatype::Array_datatype	(	Datatype_uptr	subtype,
		size_t	size
	)

Construct a new completely filled Array_datatype.

Parameters

subtype	the type of the elements contained in the array
size	the number of elements the array can store

Member Function Documentation

◆ subtype()

const Datatype& PDI::Array_datatype::subtype ( ) const

Type of the elements contained in the array.

Returns: the type of the elements contained in the array

◆ size()

size_t PDI::Array_datatype::size ( ) const

Number of elements the array can store.

Returns: the number of elements the array can store

◆ start()

size_t PDI::Array_datatype::start ( ) const

id of the first actual element of the array

Returns: the id of the first actual element of the array

◆ subsize()

size_t PDI::Array_datatype::subsize ( ) const

Number of actual elements in the array.

Returns: the number of actual elements in the array

◆ clone()

Datatype_template_uptr PDI::Array_datatype::clone ( ) const

overridevirtual

Creates a new datatype as an exact copy of this one.

Returns: the dense type that is produced

Implements PDI::Datatype_template.

◆ clone_type()

Datatype_uptr PDI::Array_datatype::clone_type ( ) const

overridevirtual

Creates a new datatype as an exact copy of this one.

Returns: the dense type that is produced

Implements PDI::Datatype.

◆ densify()

Datatype_uptr PDI::Array_datatype::densify ( ) const

overridevirtual

Creates a new datatype as the dense copy of this one.

Returns: the type that is produced

Implements PDI::Datatype.

◆ evaluate()

Datatype_uptr PDI::Array_datatype::evaluate ( Context & ctx ) const

overridevirtual

Creates a new datatype by resolving the value of all metadata references.

Parameters

ctx	the context in which to evaluate this template

Returns: the evaluated type that is produced

Implements PDI::Datatype_template.

◆ dense()

bool PDI::Array_datatype::dense ( ) const

overridevirtual

Indicate if the datatype is dense or not.

Returns: whether the datatype is dense

Implements PDI::Datatype.

◆ datasize()

size_t PDI::Array_datatype::datasize ( ) const

overridevirtual

Computes the data size of a type, excluding potentially unused memory from a sparse type.

Returns: the size in bytes

Implements PDI::Datatype.

◆ buffersize()

size_t PDI::Array_datatype::buffersize ( ) const

overridevirtual

Computes the data size of a type, including potentially unused memory from a sparse type.

Returns: the size in bytes

Implements PDI::Datatype.

◆ alignment()

size_t PDI::Array_datatype::alignment ( ) const

overridevirtual

Returns the required alignment for a type.

Returns: the size in bytes

Implements PDI::Datatype.

◆ simple()

bool PDI::Array_datatype::simple ( ) const

overridevirtual

Tells if data can be copied as bytes (if type is dense) and doesn't need a destroyer.

Returns: true if data has trivial copier and destroyer, false otherwise

Implements PDI::Datatype.

◆ data_to_dense_copy()

void* PDI::Array_datatype::data_to_dense_copy	(	void *	to,
		const void *	from
	)		const

overridevirtual

Creates a dense deep copy of data.

Parameters

[in]	to	the pointer to the allocated memory to fill (dense data)
[in]	from	the pointer to the copied data (size of buffersize)

Returns: updated `to' pointer

Implements PDI::Datatype.

◆ data_from_dense_copy()

void* PDI::Array_datatype::data_from_dense_copy	(	void *	to,
		const void *	from
	)		const

overridevirtual

Creates a sparse deep copy of dense data.

Parameters

[in]	to	the pointer to the allocated memory to fill (size of buffersize)
[in]	from	the pointer to the copied data (dense data)

Returns: updated `to' pointer

Implements PDI::Datatype.

◆ subaccess_by_iterators()

std::pair<void*, Datatype_uptr> PDI::Array_datatype::subaccess_by_iterators	(	void *	from,
		std::vector< std::unique_ptr< Accessor_base >>::const_iterator	remaining_begin,
		std::vector< std::unique_ptr< Accessor_base >>::const_iterator	remaining_end
	)		const

overridevirtual

Creates datatype of subtype and returns it with a moved pointer.

Parameters

[in]	from	the pointer to the data
[in]	remaining_begin	iterator to the begin of remaining accessors
[in]	remaining_end	iterator to the end of remaining accessors

Returns: pointer moved by offset and new datatype

Reimplemented from PDI::Datatype.

◆ destroy_data()

void PDI::Array_datatype::destroy_data ( void * ptr ) const

overridevirtual

Function used to delete the data behind the datatype.

This should not deallocate the memory.

Parameters

[in] ptr to the data to free

Implements PDI::Datatype.

◆ debug_string()

std::string PDI::Array_datatype::debug_string ( ) const

overridevirtual
