Detailed Description

Constructor & Destructor Documentation

◆ ElementBlock() [1/2]

Ioss::ElementBlock::ElementBlock	(	DatabaseIO *	io_database,
		const std::string &	my_name,
		const std::string &	element_type,
		int64_t	number_elements )

Create an element block.

Parameters

[in]	io_database	The database associated with the region containing the element block.
[in]	my_name	The element block's name.
[in]	element_type	The name of the element topology type for the element block.
[in]	number_elements	The number of elements in the element block.

◆ ElementBlock() [2/2]

Ioss::ElementBlock::ElementBlock ( const ElementBlock & )

default

Member Function Documentation

◆ contains_string()

IOSS_NODISCARD std::string Ioss::ElementBlock::contains_string ( ) const

inlineoverridevirtual

What does this entity contain.

Returns: The name of the thing this entity contains.

Implements Ioss::GroupingEntity.

◆ equal()

bool Ioss::ElementBlock::equal ( const Ioss::ElementBlock & rhs ) const

◆ get_block_adjacencies() [1/2]

Ioss::NameList Ioss::ElementBlock::get_block_adjacencies ( ) const

◆ get_block_adjacencies() [2/2]

void Ioss::ElementBlock::get_block_adjacencies ( Ioss::NameList & block_adjacency ) const

◆ get_bounding_box()

AxisAlignedBoundingBox Ioss::ElementBlock::get_bounding_box ( ) const

◆ get_implicit_property()

Property Ioss::ElementBlock::get_implicit_property ( const std::string & my_name ) const

overridevirtual

Calculate and get an implicit property.

These are calculated from data stored in the EntityBlock instead of having an explicit value assigned. An example would be 'topology_node_count' for an ElementBlock. Note that even though this is a pure virtual function, an implementation is provided to return properties that are common to all 'block'-type grouping entities. Derived classes should call 'EntityBlock::get_implicit_property' if the requested property is not specific to their type.

Implements Ioss::EntityBlock.

◆ internal_get_field_data()

int64_t Ioss::ElementBlock::internal_get_field_data	(	const Field &	field,
		void *	data,
		size_t	data_size ) const

overrideprotectedvirtual

int64_t Ioss::ElementBlock::internal_get_zc_field_data	(	const Field &	field,
		void **	data,
		size_t *	data_size ) const

overrideprotectedvirtual

Implements Ioss::GroupingEntity.

◆ internal_put_field_data()

int64_t Ioss::ElementBlock::internal_put_field_data	(	const Field &	field,
		void *	data,
		size_t	data_size ) const

overrideprotectedvirtual

Implements Ioss::GroupingEntity.

◆ operator!=()

bool Ioss::ElementBlock::operator!= ( const Ioss::ElementBlock & rhs ) const

bool Ioss::ElementBlock::operator== ( const Ioss::ElementBlock & rhs ) const

◆ short_type_string()

IOSS_NODISCARD std::string Ioss::ElementBlock::short_type_string ( ) const

inlineoverridevirtual

Get a short name of the particular type of entity.

Returns: The short name of the particular type of entity.

Implements Ioss::GroupingEntity.

◆ type()

IOSS_NODISCARD EntityType Ioss::ElementBlock::type ( ) const

inlineoverridevirtual

Get the EntityType, which indicates the particular type of GroupingEntity this is.

Returns: The particular EntityType of this GroupingEntity.

Implements Ioss::GroupingEntity.

◆ type_string()

IOSS_NODISCARD std::string Ioss::ElementBlock::type_string ( ) const

inlineoverridevirtual

Get the name of the particular type of entity.

Returns: The name of the particular type of entity.

Implements Ioss::GroupingEntity.
