Constructor Detail

WmsDataSource

public WmsDataSource()

Dummy constructor so this object can get unpersisted.

WmsDataSource

public WmsDataSource(DataSourceDescriptor descriptor,
                     List selections,
                     Hashtable properties)
              throws VisADException

Create a WmsDataSource from the specification given.

Parameters:

descriptor - descriptor for the data source

selections - The selections

properties - extra properties

Throws:

VisADException - some problem occurred creating data

Method Detail

getLayerList

public List getLayerList()

_more_

Returns:

_more_

initAfterUnpersistence

public void initAfterUnpersistence()

Initialize after we have been unpersisted

Specified by:

initAfterUnpersistence in interface DataSource

Overrides:

initAfterUnpersistence in class DataSourceImpl

doMakeDataChoices

protected void doMakeDataChoices()

Create the data choices associated with this source.

Overrides:

doMakeDataChoices in class DataSourceImpl

getDataInner

protected Data getDataInner(DataChoice dataChoice,
                            DataCategory category,
                            DataSelection dataSelection,
                            Hashtable requestProperties)
                     throws VisADException,
                            RemoteException

Actually get the data identified by the given DataChoce. The default is to call the getDataInner that does not take the requestProperties. This allows other, non unidata.data DataSource-s (that follow the old API) to work.

Overrides:

getDataInner in class DataSourceImpl

Parameters:

dataChoice - The data choice that identifies the requested data.

category - The data category of the request.

dataSelection - Identifies any subsetting of the data.

requestProperties - Hashtable that holds any detailed request properties.

Returns:

The visad.Data object

Throws:

RemoteException - Java RMI problem

VisADException - VisAD problem

getPropertiesComponents

public void getPropertiesComponents(List comps)

_more_

Overrides:

getPropertiesComponents in class DataSourceImpl

Parameters:

comps - _more_

applyProperties

public boolean applyProperties()

_more_

Overrides:

applyProperties in class DataSourceImpl

Returns:

_more_

Get the description. This adds on the last url requested.

Specified by:

getFullDescription in interface DataSource

Overrides:

getFullDescription in class DataSourceImpl

Returns:

description

shouldCache

protected boolean shouldCache(Data data)

See if this DataSource should cache or not

Overrides:

shouldCache in class DataSourceImpl

Parameters:

data - Data to cache

Returns:

setWmsSelections

public void setWmsSelections(List value)

Set the WmsSelections property.

Parameters:
