Package dap4.cdm

Class NodeMap<CDM_T extends ucar.nc2.CDMNode,DAP_T extends dap4.core.dmr.DapNode>

java.lang.Object

dap4.cdm.NodeMap<CDM_T,DAP_T>

public class NodeMap<CDM_T extends ucar.nc2.CDMNode,DAP_T extends dap4.core.dmr.DapNode>
extends Object

Provide a bi-directional 1-1 map between DapNode instances and CDMNode instances.

There is a complication. Currently, the hashCode() in ucar.nc2.Variable (and other classes) is unstable when objects are being incrementally constructed. So until and unless that is changed, it is necessary to provide a way to map CDMNode <-> DapNode that is independent of e.g Variable.hashCode(); We do this by overriding hashCode() to use Object.hashCode() explicitly.
