| static

H5Pmodify_filter modifies the specified FILTER in the transient or permanent output filter pipeline depending on whether PLIST is a dataset creation or dataset transfer property list. The FLAGS argument specifies certain general properties of the filter and is documented below. The CD_VALUES is an array of CD_NELMTS integers which are auxiliary data for the filter. The integer values will be stored in the dataset object header as part of the filter information.

The FLAGS argument is a bit vector of the following fields:

H5Z_FLAG_OPTIONAL(0x0001) If this bit is set then the filter is optional. If the filter fails during an H5Dwrite() operation then the filter is just excluded from the pipeline for the chunk for which it failed; the filter will not participate in the pipeline during an H5Dread() of the chunk. If this bit is clear and the filter fails then the entire I/O operation fails. If this bit is set but encoding is disabled for a filter, attempting to write will generate an error.

Note: This function currently supports only the permanent filter pipeline. That is, PLIST_ID must be a dataset creation property list.

Parameters

  plist | IN: Property list identifier.
  filter | IN: Filter to be modified to the pipeline.
  flags | IN: Bit vector specifying certain general properties of the filter.

## ◆ H5Pset_buffer_size()

synchronized native void H5Pset_buffer_size | ( | long | plist,
|  | long | size ) throws HDF5LibraryException, IllegalArgumentException
| static

H5Pset_buffer sets type conversion and background buffers. status to TRUE or FALSE.

Given a dataset transfer property list, H5Pset_buffer sets the maximum size for the type conversion buffer and background buffer and optionally supplies pointers to application-allocated buffers. If the buffer size is smaller than the entire amount of data being transferred between the application and the file, and a type conversion buffer or background buffer is required, then strip mining will be used.

Note that there are minimum size requirements for the buffer. Strip mining can only break the data up along the first dimension, so the buffer must be large enough to accommodate a complete slice that encompasses all of the remaining dimensions. For example, when strip mining a 100x200x300 hyperslab of a simple data space, the buffer must be large enough to hold 1x200x300 data elements. When strip mining a 100x200x300x150 hyperslab of a simple data space, the buffer must be large enough to hold 1x200x300x150 data elements.

Parameters

  plist | Identifier for the dataset transfer property list.

Exceptions

  HDF5LibraryException | Error from the HDF5 Library.
