public class TLcyContourBackEnd
extends ALcyTEABackEnd

Back-end functionality for a TEA contour add-on. It provides the following functionality to calculate contour lines:

• an altitude descriptor to create a referenced matrix view with;
• a referenced matrix view factory;
• a contour finder to apply on a referenced matrix view.

Constructor Details

TLcyContourBackEnd

public TLcyContourBackEnd(ILcyLucyEnv aLucyEnv)

Default constructor for the contour back-end.

Parameters:

aLucyEnv - the Lucy environment for which the back-end will be used

Method Details

createModelDescriptor

public ILcdModelDescriptor createModelDescriptor(ALcyProperties aProperties)

Returns a model descriptor suitable for the add-on's used models.

Specified by:

createModelDescriptor in class ALcyTEABackEnd

Parameters:

aProperties - a properties object with the following parameters:

• ALcyTEABackEnd.SOURCE_NAME_KEY: The source name that was used to retrieve the data from, use null to indicate that it was created from scratch.
• ALcyTEABackEnd.DISPLAY_NAME_KEY: the display name that the model descriptor should use @return a suitable model descriptor

Returns:

a contour model descriptor

createAltitudeDescriptor

public TLcdAltitudeDescriptor createAltitudeDescriptor(ALcyProperties aProperties)

Returns an altitude descriptor suitable for the add-on's purposes.

Note that this descriptor can be used by the back-end's contour finder; it does not include Double.NaN values.

Overrides:

createAltitudeDescriptor in class ALcyTEABackEnd

Parameters:

aProperties - this implementation does not use any properties

Returns:

an altitude descriptor suitable for the add-on's purposes

createContourFinder

public TLcdContourFinder createContourFinder(ALcyProperties aProperties)

Creates a new contour finder to generate contour lines with.

Parameters:

aProperties - this implementation does not need any properties

Returns:

a new contour finder
