Class H5Dataset.H5Dataspace

java.lang.Object

ubic.gemma.core.loader.util.hdf5.H5Dataset.H5Dataspace

All Implemented Interfaces:

AutoCloseable

Enclosing class:

H5Dataset

public class H5Dataset.H5Dataspace
extends Object
implements AutoCloseable

Represents a dataspace selection of a H5Dataset.

When collecting the space (i.e. using toByteVector(long)}), the underlying HDF5 resource is closed automatically.

Method Details

toByteVector

@WillClose
public void toByteVector(byte[] buf,
 long start,
 long end,
 long scalarType)

Write the dataspace into a slice of a target.

The start and end are expressed in terms of number of datapoints. The slice must contain exactly size() datapoints to be valid.

The dataspace is closed once the operation is completed and should no-longer be used.

Parameters:

buf - a target buffer of size (end - start) * sizeof(scalarType)

start - start of a slice. inclusive

end - end of a slice, exclusive

scalarType - a datatype to write into the buffer

toByteVector

@WillClose
public byte[] toByteVector(long scalarType)

toBooleanVector

public boolean[] toBooleanVector()

toIntegerVector

@WillClose
public int[] toIntegerVector()

toDoubleVector

@WillClose
public double[] toDoubleVector()

size

public long size()

Obtain the size of this dataspace.
