## Detailed Description

A collection of elements having the same topology.

## Constructor & Destructor Documentation

## ◆ ElementBlock()

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()

Ioss::ElementBlock::~ElementBlock | ( |  | ) |
| override default

## Member Function Documentation

## ◆ get_block_adjacencies()

void Ioss::ElementBlock::get_block_adjacencies | ( | std::vector< std::string > & | 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
| override virtual

Calculate and get an implicit property.

These are calcuated 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
| override protected virtual

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
| override protected virtual

Implements Ioss::GroupingEntity.

## ◆ short_type_string()

std::string Ioss::ElementBlock::short_type_string | ( |  | ) | const
| inline override virtual

Get a short name of the particular type of entity.

Returns
  The short name of the particular type of entity.

Implements Ioss::GroupingEntity.

## ◆ type()

EntityType Ioss::ElementBlock::type | ( |  | ) | const
| inline override virtual

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

Returns
  The particular EntityType of this GroupingEntity.

Implements Ioss::GroupingEntity.

## ◆ type_string()

std::string Ioss::ElementBlock::type_string | ( |  | ) | const
| inline override virtual

Get the name of the particular type of entity.

Returns
  The name of the particular type of entity.

Implements Ioss::GroupingEntity.
