java.lang.Object

thredds.core.DataRootManager

All Implemented Interfaces:

org.springframework.beans.factory.InitializingBean

@Component
public class DataRootManager
extends java.lang.Object
implements org.springframework.beans.factory.InitializingBean

The DataRootHandler manages all the "data roots" for a TDS and provides mappings from URLs to catalog and datasets.

The "data roots" are read in from one or more trees of config catalogs and are defined by the datasetScan and datasetRoot and featureCollection elements in the config catalogs.

afterPropertiesSet

public void afterPropertiesSet()
                        throws java.lang.Exception

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

Throws:

java.lang.Exception

setDataRootPathMatcher

public void setDataRootPathMatcher(thredds.server.catalog.DataRootPathMatcher dataRootPathMatcher)

findDataRootMatch

public DataRootManager.DataRootMatch findDataRootMatch(java.lang.String spath)

getLocationFromRequestPath

public java.lang.String getLocationFromRequestPath(java.lang.String reqPath)

Return the the location to which the given path maps. Null is returned if the dataset does not exist, the matching DatasetScan or DataRoot filters out the requested MFile, the MFile does not represent a File (i.e., it is not a CrawlableDatasetFile), or an I/O error occurs

Parameters:

reqPath - the request path.

Returns:

the location of the file on disk, or null

Throws:

java.lang.IllegalStateException - if the request is not for a descendant of (or the same as) the matching DatasetRoot collection location.
