Constructor Detail

TLcdMultivaluedRaster

public TLcdMultivaluedRaster(ILcdRaster[] aRasters)

Creates a new TLcdMultivaluedRaster.

Parameters:

aRasters - the ILcdRaster objects corresponding to the value dimensions.

TLcdMultivaluedRaster

public TLcdMultivaluedRaster(ILcdRaster[] aRasters,
                             ILcdBounds aBounds)

Creates a new TLcdMultivaluedRaster.

Parameters:

aRasters - the ILcdRaster objects corresponding to the value dimensions.

aBounds - the global bounds of all contained rasters.

Method Detail

getRasterCount

public int getRasterCount()

getRaster

public ILcdRaster getRaster(int aLevel)

getBounds

public ILcdBounds getBounds()

Description copied from interface: ILcdBounded

Returns the ILcdBounds by which the geometry of this ILcdBounded object is bounded.

If the geometry does not allow retrieving valid bounds (for example a polyline with 0 points) the return value is unspecified. It is highly recommended to return an undefined bounds. You can create undefined bounds using the default constructors of TLcdLonLatBounds or TLcdXYBounds.

Specified by:

getBounds in interface ILcdBounded

Returns:

the ILcdBounds by which the geometry of this ILcdBounded object is bounded.

retrieveValue

public int retrieveValue(double aX,
                         double aY,
                         int aIndex)

Description copied from interface: ILcdMultivaluedRaster

Retrieves a single value from the values at the given point.

Specified by:

retrieveValue in interface ILcdMultivaluedRaster

Parameters:

aX - the abscissa of the required value.

aY - the ordinate of the required value.

aIndex - the index of the raster.

Returns:

a value of type integer.

retrieveValuesSFCT

public void retrieveValuesSFCT(double aX,
                               double aY,
                               int[] aValuesSFCT)

Description copied from interface: ILcdMultivaluedRaster

Retrieves the values at the given point.

Specified by:

retrieveValuesSFCT in interface ILcdMultivaluedRaster

Parameters:

aX - the abscissa of the required value.

aY - the ordinate of the required value.

aValuesSFCT - an array of the proper size in which the values will be written.

insertIntoCache

public void insertIntoCache(Object aKey,
                            Object aObject)

Description copied from interface: ILcdCache

Inserts a cache Object corresponding to the given key Object.

Specified by:

insertIntoCache in interface ILcdCache

Parameters:

aKey - the key Object that will be used to identify the Object. The key must therefore be a unique identifier, typically the caller itself: insertIntoCache(this, ...).

aObject - the Object to be cached.

getCachedObject

public Object getCachedObject(Object aKey)

Description copied from interface: ILcdCache

Looks up and returns the cached Object corresponding to the given key.

Specified by:

getCachedObject in interface ILcdCache

Parameters:

aKey - the key Object that was used for storing the cache Object.

Returns:

the cached Object, or null if there is no Object corresponding to the given key.

removeCachedObject

public Object removeCachedObject(Object aKey)

Description copied from interface: ILcdCache

Looks up and removes the cached Object corresponding to the given key.

Specified by:

removeCachedObject in interface ILcdCache

Parameters:

aKey - the key Object that was used for storing the cache Object.

Returns:

the cached Object, or null if there was no Object corresponding to the given key.

clearCache

public void clearCache()

Description copied from interface: ILcdCache

Clears the cache.

Specified by:

clearCache in interface ILcdCache
