All Implemented Interfaces:

CDMArray

public class CDMArrayStructure
extends ucar.ma2.ArrayStructure
implements CDMArray

Implementation of ArrayStructure that wraps DAP4 databuffer (Note: Needs serious optimization applied).

Given Structure S {f1,f2,...fm} [d1][d2]...[dn], internally, this is stored as a 2-D array CDMArray[][] instances; The first dimension's length is d1*d2*...dn. The second dimension has size |members| i.e. the number of fields in the sequence.

protected long nmembers

instances

protected ucar.ma2.Array[][] instances

Since we are using StructureData, we do not actually need to keep the D4DataStructure instances as such. We need a mapping from index X member to a CDMArray object. Total number of objects is dimsize * |members|. Accessed by StructureData.
