DataSpace: The DataSpace Class

Description

The DataSpace class used to select data elements from DataSet objects. DataSpace objects can be generated using the S4--method selectDataSpace from DataSets objects in 3 ways:

1. Without any parameters: Select all elements inDataSet

. With offset and count: Select contiguous sub--region (hyperslab) from DataSet. With parameter elem: Select sub-elements specified by matrix holding selected indices. This selection type can become slow for many data points.

Usage

## S3 method for class 'DataSpace':
h5close(.Object)
selectDataSpace(.Object, offset = rep(NA_integer_, length(.Object@dim)),
  count = rep(NA_integer_, length(.Object@dim)), elem)
## S3 method for class 'DataSet,missing,missing,missing':
selectDataSpace(.Object)
## S3 method for class 'DataSet,ANY,ANY,missing':
selectDataSpace(.Object, offset, count)
## S3 method for class 'DataSet,missing,missing,matrix':
selectDataSpace(.Object, elem)

Arguments

.Object

DataSet; S4 object of class DataSet (DataSpace for h5close).

offset

numeric; Offset to be selected from Hyperslab.

count

numeric; Count to be selected from Hyperslab.

elem

matrix; Matrix specifying element selection coordinates. Columns specify rank, rows specify different points.

...
