Class RegExpAndDurationTimeCoverageEnhancer

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

All Implemented Interfaces:

DatasetEnhancer

public class RegExpAndDurationTimeCoverageEnhancer
extends 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.

Method Detail

getInstanceToMatchOnDatasetName

public static RegExpAndDurationTimeCoverageEnhancer getInstanceToMatchOnDatasetName(String matchPattern,
                                                                                    String substitutionPattern,
                                                                                    String duration)

Factory method that returns a RegExpAndDurationTimeCoverageEnhancer instance that will apply the match pattern to the dataset name.

Parameters:

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

substitutionPattern - the time coverage start time (which may contain regular expression capturing group substitution strings).

duration - the time coverage duration string.

Returns:

a RegExpAndDurationTimeCoverageEnhancer that will apply the match pattern to the dataset name.

getInstanceToMatchOnDatasetPath

public static RegExpAndDurationTimeCoverageEnhancer getInstanceToMatchOnDatasetPath(String matchPattern,
                                                                                    String substitutionPattern,
                                                                                    String duration)

Factory method that returns a RegExpAndDurationTimeCoverageEnhancer instance that will apply the match pattern to the dataset path.

Parameters:

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

substitutionPattern - the time coverage start time (which may contain regular expression capturing group substitution strings).

duration - the time coverage duration string.

Returns:

a RegExpAndDurationTimeCoverageEnhancer that will apply the match pattern to the dataset path.

getConfigObject

public Object getConfigObject()

Description copied from interface: DatasetEnhancer

Return the configuration object.

Specified by:

getConfigObject in interface DatasetEnhancer

Returns:

the configuration Object (may be null).

addMetadata

public boolean addMetadata(InvDataset dataset,
                           CrawlableDataset crDataset)

Description copied from interface: DatasetEnhancer

Add metadata to the given InvDataset possibly using information from the corresponding CrawlableDataset.

Specified by:

addMetadata in interface DatasetEnhancer

Parameters:

dataset - the InvDataset to enhance with additional metadata.

crDataset - the CrawlableDataset that corresponds with the given InvDataset, possibly used to gather information not available from the InvDataset.

Returns:

true if the InvDataset is successfully enhanced, otherwise false.
