Class CollectionSpecParser

java.lang.Object

thredds.inventory.CollectionSpecParserAbstract

thredds.inventory.CollectionSpecParser

public class CollectionSpecParser
extends CollectionSpecParserAbstract

Parses the collection specification string for local files.

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)
