HydraDataSource

public HydraDataSource()

Default constructor

HydraDataSource

public HydraDataSource(ucar.unidata.data.DataSourceDescriptor descriptor,
                       java.util.List newSources,
                       java.lang.String description,
                       java.util.Hashtable properties)
                throws VisADException

Create a HydraDataSource

Parameters:

descriptor - The datasource descriptor

newSources - List of files or urls

is the data from files

clearCachedData

public void clearCachedData()

This is called when the CacheManager detects the need ot clear memory. It is intended to be overwritten by derived classes that are holding cached data that is not in the normal putCache facilities provided by this class since that data is actually managed by the CacheManager

Specified by:

clearCachedData in interface ucar.unidata.data.DataSource

Overrides:

clearCachedData in class ucar.unidata.data.DataSourceImpl

getAdapters

protected java.util.List getAdapters()

Create, if needed, and return the list of adapters. Will return null if there are no valid adapters.

Returns:

List of adapters or null

makeAdapters

private void makeAdapters(java.util.List files)
                   throws java.lang.Exception

Make the adapters for the given list of files

Parameters:

files - Data files

Throws:

java.lang.Exception - When bad things happen

doMakeDateTimes

protected java.util.List doMakeDateTimes()

Create the list of times associated with this DataSource.

Overrides:

doMakeDateTimes in class ucar.unidata.data.DataSourceImpl

Returns:

list of times.

getDataInner

protected Data getDataInner(ucar.unidata.data.DataChoice dataChoice,
                            ucar.unidata.data.DataCategory category,
                            ucar.unidata.data.DataSelection subset,
                            java.util.Hashtable requestProperties)
                     throws VisADException,
                            java.rmi.RemoteException

Get the data for the given DataChoice and selection criteria.

Overrides:

getDataInner in class ucar.unidata.data.DataSourceImpl

Parameters:

dataChoice - DataChoice for selection

category - DataCategory for the DataChoice (not used)

subset - subsetting criteria

requestProperties - extra request properties

Returns:

the Data object for the request

Throws:
