## Member Function Documentation

## ◆ deleteConstants()

void deleteConstants | ( |  | ) |
| static

## ◆ fromClass()

virtual std::string fromClass | ( |  | ) | const
| override virtual

Returns this class name.

Reimplemented from LinkAccPropList.

## ◆ getChunkCache()

void getChunkCache | ( | size_t & | rdcc_nslots,
|  | size_t & | rdcc_nbytes,
|  | double & | rdcc_w0 ) const

Retrieves the raw data chunk cache parameters.

Parameters

  rdcc_nslots | - OUT: Number of chunk slots in the raw data chunk cache
  rdcc_nbytes | - OUT: Total size of the raw data chunk cache
  rdcc_w0 | - OUT: The chunk preemption policy for this dataset

Exceptions

  H5::PropListIException |

Description
  For information, please refer to the H5Pget_chunk_cache API in the HDF5 C Reference Manual.

## ◆ setChunkCache()

void setChunkCache | ( | size_t | rdcc_nslots,
|  | size_t | rdcc_nbytes,
|  | double | rdcc_w0 ) const

Sets the raw data chunk cache parameters.

Parameters

  rdcc_nslots | - IN: Number of chunk slots in the raw data chunk cache
  rdcc_nbytes | - IN: Total size of the raw data chunk cache
  rdcc_w0 | - IN: The chunk preemption policy for this dataset

Exceptions

  H5::PropListIException |

Description
  The raw data chunk cache parameters includes the number of objects in the meta data cache and the maximum number of chunks and bytes in the raw data chunk cache. Once set, these values will override the values in the file access property list.

For information, please refer to the H5Pset_chunk_cache API in the HDF5 C Reference Manual.
