getDataStructure

public DataStructure<?> getDataStructure(int dataType,
                                int dataspace_id)
                                  throws ncsa.hdf.hdf5lib.exceptions.HDF5LibraryException

Returns a DataStructure with the requested data type and dimensions of the provided dataspace

Parameters:

dataType - Type of data. Type can be DOUBLE, INTEGER, STRING

dataspace_id - The identifier of the dataspace. It'll be used to calcualte the dimensions of DataStructure to be return.

Returns:

DataStructure with data array of type dataType and dimensions calculated from provided dataspace. Return null if the info provided require a structure not yet supported or dataspace doesn't exist.

Throws:

ncsa.hdf.hdf5lib.exceptions.HDF5LibraryException

getDataStructure

public DataStructure<?> getDataStructure(int dataType,
                                int num_dimensions,
                                long[] dimensions)

Returns a DataStructure with the requested data type and dimensions provided

Parameters:

dataType - Type of data. Type can be DOUBLE, INTEGER, STRING

num_dimensions - It's the rank of array. It can be 1, 2 or 3 for Integer or Double. It can be 1 for String.

dimensions - It give the dimension of each array.

Returns:

DataStructure with data array of type dataType and dimensions as provided. Return null if the info provided require a structure not yet supported.
