Class DatasetManager

java.lang.Object

thredds.core.DatasetManager

All Implemented Interfaces:

org.springframework.beans.factory.InitializingBean

@Component
public class DatasetManager
extends java.lang.Object
implements org.springframework.beans.factory.InitializingBean

Provides an API to obtain the various Dataset objects, given the request Path.

Need to rethink return type - using null to mean many things

Since:

1/23/2015 This needs revision to separate out the url path stuff from the more general file stuff.
