Examples of jsky.catalog.QueryArgs

jsky.catalog.QueryArgs
An interface representing the values of the arguments to a catalog query. The values correspond one to one with a given catalog's parameters, as returned by the Catalog.getParamDesc(index) method. @see Catalog#getNumParams @see Catalog#getParamDesc
