H5Dataset.H5Dataspace (Gemma 1.32.0 API)

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.

  - toByteVector
```
@WillClose
public void toByteVector(byte[] buf,
                         int start,
                         int 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
