H5Ref-class: An S4 class representing H5 references.

In grimbough/rhdf5: R Interface to HDF5

An S4 class representing H5 references.

Description

A class representing one or more HDF5 references.

Usage

## S4 method for signature 'H5Ref'
show(object)

## S4 method for signature 'H5Ref'
length(x)

## S4 method for signature 'H5Ref'
c(x, ...)

## S4 method for signature 'H5Ref'
x[i]

Arguments

object	Object of class H5Ref
x	An H5Ref object.
...	Additional H5Ref objects to be combined with x.
i	Integer vector giving the indices of references to select.

Details

The length of the val slot is dependent on both the number and type of references stored in the object. H5R_OBJECT references are stored in 8 bytes, while H5R_DATASET_REGION references require 12 bytes. The length of val will then be a multiple of 8 or 12 respectively. This also means that references of different types cannot be combined in a single object.

Methods (by generic)

• show(H5Ref): Print details of the object to screen.

• length(H5Ref): Return the number of references stored in an H5Ref object.

• c(H5Ref): Combine two or more H5Ref objects. Objects must all contain the same type of reference, either H5R_OBJECT or H5R_DATASET_REFERENCE.

• [: Subset an H5Ref object.

Slots

val

raw vector containing the byte-level representation of each reference.

type

integer of length 1, which maps to either H5R_OBJECT or H5R_DATASET_REGION.
