Class Fmrc

java.lang.Object

ucar.nc2.ft.fmrc.Fmrc

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

@ThreadSafe
public class Fmrc
extends java.lang.Object
implements java.io.Closeable

Forecast Model Run Collection, manages dynamic collections of GridDatasets. Fmrc represents a virtual dataset. To instantiate, you obtain an FmrcInv "snapshot" from which you can call getDatatset().

Assumes that we dont have multiple runtimes in the same file. Can handle different time steps in different files. Can handle different grids in different files. However this creates problems for the "typical dataset". Cannot handle different ensembles in different files. (LOOK fix) Cannot handle different levels in different files. ok
