fillFromDatasetDefinitions

public abstract Envelope fillFromDatasetDefinitions(Envelope sceneEnvelope,
                                                    double[] translationToLocalCRS,
                                                    XMLAdapter configAdapter,
                                                    DatasetDefinitions dsd)

Fill the wrapper with the values from the given dataset definition.

Parameters:

sceneEnvelope - whic should be enlarged for all configured datasets, it is 3D!! in real world coordinates.

translationToLocalCRS - which was configured

configAdapter - to resolve urls

dsd - containing the datasets.

Returns:

the merged scene envelope

clarifyMaxPixelError

protected Double clarifyMaxPixelError(Double parentMaxPixelError,
                                      Double maxPixelError)

Parameters:

parentMaxPixelError -

maxPixelError -

Returns:

the parent or the max pixel error if not null.

isUnAmbiguous

protected boolean isUnAmbiguous(String name)

Parameters:

name - of dataset

Returns:

true if a dataset was previously defined with the given name.

size

public int size()

Returns:

the number of configured datasets.

addConstraint

protected boolean addConstraint(String name,
                                CO datasourceObject,
                                Envelope bbt)

Add a constrained to the given name of a dataset.

Parameters:

name -

datasourceObject -

bbt - in the WPVS scene coordinate system.

Returns:

                                             ViewParams viewParams)

Matches the given names to the configured datasets and tests retrieves the datasources/datasets which match the names and the viewparams.

Parameters:

requestedDatasets -

viewParams -

Returns:

the list of matching objects, never null

datasetTitles

public Set<String> datasetTitles()

Returns:

all configured and requestable titles known to this dataset type.

resolve
