ucar.ma2.Array

ucar.ma2.ArrayStructure

dap4.cdm.CDMArrayStructure

All Implemented Interfaces:

CDMArray

public class CDMArrayStructure
extends 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 CDMDataset root

dsp

protected D4DSP dsp

template

protected DapVariable template

bytesize

protected long bytesize

basetype

protected DapType basetype

primitivetype

protected AtomicType primitivetype

d4data

protected D4DataCompoundArray d4data

dimsize

protected long dimsize

nmembers

protected long nmembers

instances

protected 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.

getStructureData

public StructureData getStructureData(int index)

Get the index'th StructureData(StructureDataA) object We need instances of StructureData to give to the user. We use StructureDataA so we can centralize everything in this class. The total number of StructureData objects is dimsize.

Overrides:
