Constructor Detail

WMTSTileService

public WMTSTileService(String templateURL,
                       WMTSServiceType type,
                       WMTSLayer layer,
                       String styleName,
                       TileMatrixSet tileMatrixSet)

create a service directly with out parsing the capabilties again.

Parameters:

requestURL - - where to ask for tiles

type - - KVP or REST

layerName - - name of the layer to request

styleName - - name of the style to use?

tileMatrixSetName - - matrixset name

Method Detail

getReqExtentInTileCrs

protected ReferencedEnvelope getReqExtentInTileCrs(ReferencedEnvelope requestedExtent)

findTilesInExtent

public Set<Tile> findTilesInExtent(ReferencedEnvelope requestedExtent,
                                   int scaleFactor,
                                   boolean recommendedZoomLevel,
                                   int maxNumberOfTiles)

Overrides:

findTilesInExtent in class TileService

addTileToCache

protected Tile addTileToCache(Tile tile)

Add a tile to the cache.

At the moment we are delegating the cache to the super class, which handles the cache as a soft cache. The soft cache has an un-controllable time to live, could last a split seconds or 100 years. However, WMTS services normally come with caching headers of some sort, e.g., do not cache, or keep for 1 hour, or 6 months and so on.

TODO: The code should account for that.

Overrides:

addTileToCache in class TileService

getType

public WMTSServiceType getType()

Returns:

the type

setType

public void setType(WMTSServiceType type)

Parameters:

type - the type to set

getLayerName

public String getLayerName()

Returns:

the layerName

getStyleName

public String getStyleName()

Returns:

the styleName

setStyleName

public void setStyleName(String styleName)

Parameters:

styleName - the styleName to set

getScaleList

public double[] getScaleList()

Description copied from class: TileService

Returns a list that represents a mapping between zoom-levels and map scale.

Specified by:

getScaleList in class TileService

Returns:

mapping between zoom-levels and map scale

getBounds
