Constructor Detail

XMLSurveyFinder

public XMLSurveyFinder()

Set up the SurveyFinder and populate the map. Overloaded to pass a flag for whether the context is simply to dump the survey manifest.

XMLSurveyFinder

public XMLSurveyFinder(boolean dump)

Method Detail

dump

public void dump()

Create a cached translation between survey names and files. This can be used to save a little time when running SkyView. Note that the hash that is written was already created in the XMLSurveyFinder constructor above.

read

getSurveysFromRoot

protected void getSurveysFromRoot()

Get the surveys in the document root area

getSurveysFromUser

protected void getSurveysFromUser()

Get user specified surveys

getSurveysFromMainifest

protected void getSurveysFromMainifest()

Get surveys from a user manifest. This is how SkyView-in-a-Jar gets its surveys. Result is that the XMLSurveyFinder's hash object is filled. Overloaded for case of dump

getSurveysFromManifest

protected void getSurveysFromManifest(boolean dump)

localCacheName

protected String localCacheName()

Get path to the local cache using the path to the jar file being executed.

remoteCacheName

protected String remoteCacheName()

manifestName

protected String manifestName()

manifestToHash

protected void manifestToHash()

Read XML files to populate survey hash in memory.

loadSurveyCacheFromUrl
