Add an information record (an informative string) to the database.

Parameters

  [in] | info | The string to add.

## ◆ add_information_records()

void Ioss::DatabaseIO::add_information_records | ( | const std::vector< std::string > & | info | ) |

Parameters

  [in] | info | The strings to add.

## ◆ add_qa_record()

void Ioss::DatabaseIO::add_qa_record | ( | const std::string & | code,
|  | const std::string & | code_qa,
|  | const std::string & | date,
|  | const std::string & | time
| ) |  |

Add a QA record, which consists of 4 strings, to the database.

The 4 function parameters correspond to the 4 QA record strings.

Parameters

  [in] | code | A descriptive code name, such as the application that modified the database.
  [in] | code_qa | A descriptive string, such as the version of the application that modified the database.
  [in] | date | A relevant date, such as the date the database was modified.
  [in] | time | A relevant time, such as the time the database was modified.

## ◆ begin()

bool Ioss::DatabaseIO::begin | ( | Ioss::State | state | ) |
| inline

Set the database to the given State.

All transitions must begin from the 'STATE_CLOSED' state or be to the 'STATE_CLOSED' state (There are no nested begin/end pairs at this time.)

The database state is automatically set when Region::begin_mode is called for its associated region, so it may not be necessary to call this method directly.

Parameters

  [in] | state | The new State to which the database should be set.

Returns
  True if successful.

## ◆ begin__()

## ◆ check_side_topology()

void Ioss::DatabaseIO::check_side_topology | ( |  | ) | const
| protected

Check the topology of all face/element pairs in the model and fill the "TopoContainer faceTopology" variable with the unique pairs. This information is used for the faceblock/facesets and edgeblock/edgesets. If the 'topo_dimension' is 2, then face/element pairs are generated; if 'topo_dimension' is 1, then edge/element pairs are generated.

## ◆ closeDatabase()

void Ioss::DatabaseIO::closeDatabase | ( |  | ) | const
| inline

## ◆ closeDatabase__()

virtual void Ioss::DatabaseIO::closeDatabase__ | ( |  | ) | const
| inline private virtual

void Ioss::DatabaseIO::create_path | ( | const std::string & | filename | ) | const

This function is used to create the path to an output directory (or history, restart, etc.)

## ◆ create_subgroup()

bool Ioss::DatabaseIO::create_subgroup | ( | const std::string & | group_name | ) |
| inline

If a database type supports groups, create the specified group as a child of the current group.

## ◆ end()

bool Ioss::DatabaseIO::end | ( | Ioss::State | state | ) |

Utility function that may be used by derived classes. Determines whether all elements in the model have the same side topology. This can be used to speed-up certain algorithms since they don't have to check each side (or group of sides) individually.

## ◆ set_cycle_count()

void Ioss::DatabaseIO::set_cycle_count | ( | int | count | ) | const
| inline

The overlay_count specifies the number of restart outputs which will be overlaid on top of the currently written step before advancing to the next step on the restart database.

For example, if restarts are being output every 0.1 seconds and the overlay count is specified as 2, then restart will write time 0.1 to step 1 of the database. It will then write 0.2 and 0.3 also to step 1. It will then increment the database step and write 0.4 to step 2; overlay 0.5 and 0.6 on step 2... At the end of the analysis, assuming it runs to completion, the database would have times 0.3, 0.6, 0.9, ... However, if there were a problem during the analysis, the last step on the database would contain an intermediate step.

The cycle_count specifies the number of restart steps which will be written to the restart database before previously written steps are overwritten.

For example, if the cycle count is 5 and restart is written every 0.1 seconds, the restart system will write data at times 0.1, 0.2, 0.3, 0.4, 0.5 to the database.

It will then overwrite the first step with data from time 0.6, the second with time 0.7. At time 0.8, the database would contain data at times 0.6, 0.7, 0.8, 0.4, 0.5. Note that time will not necessarily be monotonically increasing on a database that specifies the cycle count.

The cycle count and overlay count can both be used at the same time also. The basic formula is:

       db_step = (((output_step - 1) / overlay) % cycle) + 1

where "output_step" is the step that this would have been on the database in a normal write (1,2,3,....) and "db_step" is the step number that this will be written to.

If you only want the last step available on the database, use set_cycle_count(1)

## ◆ properties

Ioss::PropertyManager Ioss::DatabaseIO::properties
| protected

The properties member data contains properties that can be used to set database-specific options. Examples include compression, name lengths, integer sizes, floating point sizes. By convention, the property name is all uppercase. Some existing properties recognized by the Exodus DatabaseIO class are:

Property | Value
--- | ---
COMPRESSION_LEVEL | In the range [0..9]. A value of 0 indicates no compression
COMPRESSION_SHUFFLE | (true/false) to enable/disable hdf5's shuffle compression

algorithm. | FILE_TYPE | netcdf4 | MAXIMUM_NAME_LENGTH | Maximum length of names that will be returned/passed via api call. | INTEGER_SIZE_DB | 4 or 8 indicating byte size of integers stored on the database. | INTEGER_SIZE_API | 4 or 8 indicating byte size of integers used in api functions. | LOGGING | (true/false) to enable/disable logging of field input/output

## ◆ qaRecords

std::vector<std::string> Ioss::DatabaseIO::qaRecords
| protected

## ◆ region_

Region* Ioss::DatabaseIO::region_ {nullptr}
| private

## ◆ sideTopology

TopoContainer Ioss::DatabaseIO::sideTopology
| protected

Used to speed up faceblock/edgeblock calculations.

## ◆ singleProcOnly

bool Ioss::DatabaseIO::singleProcOnly
| private

## ◆ splitType

Ioss::SurfaceSplitType Ioss::DatabaseIO::splitType {SPLIT_BY_TOPOLOGIES}
| protected

## ◆ timeScaleFactor

double Ioss::DatabaseIO::timeScaleFactor {1.0}
| protected

Scale the time read/written from/to the file by the specified scaleFactor. If the datbase times are 0.1, 0.2, 0.3 and the scaleFactor is 20, then the application will think that the times read are 20, 40, 60.

If specified for an output database, then the analysis time is divided by the scaleFactor time prior to output.

false}

## ◆ usingParallelIO

bool Ioss::DatabaseIO::usingParallelIO {false}
| protected

## ◆ util_
