Class RegExpAndDurationTimeCoverageEnhancer

java.lang.Object
  thredds.cataloggen.datasetenhancer.RegExpAndDurationTimeCoverageEnhancer

All Implemented Interfaces:

DatasetEnhancer

public class RegExpAndDurationTimeCoverageEnhancer
extends java.lang.Object
implements DatasetEnhancer

Try to add timeCoverage to the InvDataset using a regular expression match, capturing group replacement, and a duration string.

1. Look for a match to the given matchPattern in the CrawlableDataset name.
2. Substitute all replacment patterns ("$n") in the substitionPattern with the capturing groups from the regular expression match.
3. Use the string obtained from the substitution as the start time and the given duration string to form a timeCoverage element for the InvDataset.

Constructor

Parameters:

matchPattern - a regular expression used to match against the CrawlableDataset name.

substitutionPattern - used, after substitution with the regular expression capturing groups, as the start time for a time coverage.

duration - used as the duration string for a time coverage.
