H5P-class

Class for HDF5 property lists.

Description

This is the base class for all property lists, but most have a specialized class. It inherits all functions of the H5RefClass. It is also the base class for many other classes, specifically

Dataset Creation: H5P_DATASET_CREATE
Dataset Access: H5P_DATASET_ACCESS
Dataset Transfer: H5P_DATASET_XFER
Link Creation: H5P_LINK_CREATE
Link Access: H5P_LINK_ACCESS
Object Creation: H5P_OBJECT_CREATE
Object Copy: H5P_OBJECT_COPY
Attribute Creation: H5P_ATTRIBUTE_CREATE

The base class is unlikely to be needed by users - they should use the appropriate subclass required.

Value

Object of class H5P.

Methods

Create a new property list; this function itself is unlikely to be needed by users. Users should use the classes of the type they actually require

Parameters

id: Internal use only
