Constructor Detail

ResolutionInfo

public ResolutionInfo()

A resolution info for continuous coverages.

ResolutionInfo

public ResolutionInfo(SampleResolution resolution)

The info holds only one native resolution (typically from a single/tiled raster).

Parameters:

resolution - the native resolution of the coverage.

ResolutionInfo

public ResolutionInfo(List<SampleResolution> resolutions)

The info holds only one native resolution (typically a multi resolution raster).

Parameters:

resolutions - the native resolutions of the coverage.

Method Detail

getNativeResolutions

public List<SampleResolution> getNativeResolutions()

Returns the native resolutions of the coverage. A 'continuous' coverage has no sample resolutions, it therefore will return the empty list.

Returns:

the native resolutions of the given coverage or the empty list if the coverage has no 'native' resolution (for example a continuous function). Never returns null

getBestFit

public SampleResolution getBestFit(SampleResolution targetResolution,
                                   ResolutionInfo.RoundingMode mode)

Returns the best fitting (in terms of the given rounding mode) native resolution. If the given coverage does not have a native resolution the given resolution will be returned.

Parameters:

targetResolution - the required resolution.

mode - the mode of the to be used for finding the best fit.

Returns:

the SampleResolution best fitting the given target resolution and mode, if no 'native' resolution is available, the given targetResolution will be returned, never null.
