Package dap4.cdm.nc2

Class CDMCompiler

java.lang.Object

dap4.cdm.nc2.CDMCompiler

public class CDMCompiler
extends Object

The goal for the CDM compiler is produce a NetcdfDataset whose content comes from a DSP. In a sense it is the inverse of CDMDSP. Compilation implies two translations/wraps. 1. Create a set of CDMNodes corresponding to the relevant nodes in the DMR. 2. Create a set of CDM ucar.ma2.array objects that wrap the DataDataset object. Note that this compiler has nothing to do with D4DataCompiler.
