Method Detail

getPixelDensity

public double getPixelDensity()

Description copied from interface: ILcdEarthRasterAsset

Returns the asset's pixel density in pixels per square degree. In other words, this method returns the total number of pixels in the raster divided by the area of the asset's bounds. The pixel density can be used to prioritize more detailed rasters during terrain preprocessing.

Specified by:

getPixelDensity in interface ILcdEarthRasterAsset

Returns:

the asset's pixel density

compareTo

public int compareTo(Object o)

If the given asset is an TLcdEarthRasterAsset, its pixel density is compared to this raster asset's pixel density. In other words, this raster asset is less than the given raster asset if the pixel density of this raster asset is larger than the given raster asset's pixel density). Otherwise the default comparison is used.

Specified by:

compareTo in interface Comparable

Overrides:

compareTo in class TLcdEarthAsset

Parameters:

o - The object to compare this raster asset to.

Returns:

The comparison result.

See Also:

TLcdEarthAsset.compareTo(java.lang.Object), Comparable.compareTo(Object)

equals

public boolean equals(Object o)

Returns true if the given object is an earth raster asset, equals this earth asset and compares equal to this earth raster asset according to the compareTo(Object) method.

Overrides:

equals in class TLcdEarthAsset

Parameters:

o - The object to compare this raster asset to.

Returns:

True if the given object is equal to this raster asset.

compareTo(Object)

hashCode

public int hashCode()

Overrides:

hashCode in class TLcdEarthAsset
