Class CollectionSpecParser

java.lang.Object

thredds.inventory.CollectionSpecParser

@ThreadSafe
public class CollectionSpecParser
extends java.lang.Object

Parses the collection specification string.

the idea is that one copies the full path of an example dataset, then edits it

Example: "/data/ldm/pub/native/grid/NCEP/GFS/Alaska_191km/** /GFS_Alaska_191km_#yyyyMMdd_HHmm#\.grib1$"

• rootDir ="/data/ldm/pub/native/grid/NCEP/GFS/Alaska_191km"/
• subdirs=true (because ** is present)
• dateFormatMark="GFS_Alaska_191km_#yyyyMMdd_HHmm"
• regExp='GFS_Alaska_191km_.............\.grib1$

Example: "Q:/grid/grib/grib1/data/agg/.*\.grb"

• rootDir ="Q:/grid/grib/grib1/data/agg/"/
• subdirs=false
• dateFormatMark=null
• useName=yes
• regexp= ".*\.grb" (anything ending with .grb)
