                            ArrayStructure array)
                     throws DataException

Throws:

DataException

Method Detail

getElementSort

public DataSort getElementSort()

Description copied from interface: DataCompoundArray

Get the element sort; currently returns only DataSort.{SEQUENCE,STRUCTURE}

Specified by:

getElementSort in interface DataCompoundArray

Returns:

sort

getCount

public long getCount()

Description copied from interface: DataCompoundArray

Get the total number of elements in the variable array. A scalar is treated as a one element array.

Specified by:

getCount in interface DataCompoundArray

Returns:

1 if the variable is scalar, else the product of the dimensions of the variable.

read

public DataCompound read(long index)
                  throws DataException

Description copied from interface: DataCompoundArray

Provide a read of a single value at a given index in a variable.

Specified by:

read in interface DataCompoundArray

Parameters:

index - of the value to read.

Throws:

DataException

read

public void read(List<Slice> slices,
                 DataCompound[] result)
          throws DataException

For this method, the data will be a list of CDMDataStructure or (eventually) CDMDataSequence objects.

Specified by:

read in interface DataCompoundArray

Parameters:

slices - slices constraining what is to be returned.

result - the array into which the values are returned

Throws:

DataException
