HDF5ArraySeed objects

Description

HDF5ArraySeed is a low-level helper class for representing a pointer to an HDF5 dataset. HDF5ArraySeed objects are not intended to be used directly. Most end users should create and manipulate HDF5Array objects instead. See ?HDF5Array for more information.

Usage

## Constructor function:
HDF5ArraySeed(filepath, name, type=NA)

Arguments

Details

No operation can be performed directly on an HDF5ArraySeed object. It first needs to be wrapped in a DelayedArray object. The result of this wrapping is an HDF5Array object (an HDF5Array object is just an HDF5ArraySeed object wrapped in a DelayedArray object).

Value

An HDF5ArraySeed object.
