Class HTTPTileDataSource

java.lang.Object

com.nutiteq.datasources.TileDataSource

com.nutiteq.datasources.HTTPTileDataSource

public class HTTPTileDataSource
extends TileDataSource

A tile data source that loads tiles using a HTTP connection.
The requests are generated using a template scheme, where tags in the baseURL string are replaced with actual values.
The following tags are supported: zoom, x, y, xflipped, yflipped, quadkey.

For example, if baseURL = "http://tile.openstreetmap.org/{zoom}/{x}/{y}.png" and the requested tile has zoom = 2,
x = 1 and y = 3, then the tile will be loaded from the following URL: "http://tile.openstreetmap.org/2/1/3.png".

                          int maxZoom,
                          java.lang.String baseURL)

Constructs a HTTPTileDataSource object.

Parameters:

minZoom - The minimum zoom level supported by this data source.

maxZoom - The maximum zoom level supported by this data source.

baseURL - The base URL containing tags (for example, "http://tile.openstreetmap.org/{zoom}/{x}/{y}.png").

Method Detail

getCPtr

public static long getCPtr(HTTPTileDataSource obj)

finalize

protected void finalize()

Overrides:

finalize in class TileDataSource

delete

public void delete()

Overrides:

delete in class TileDataSource

swigDirectorDisconnect

protected void swigDirectorDisconnect()

Overrides:

swigDirectorDisconnect in class TileDataSource

swigReleaseOwnership

public void swigReleaseOwnership()

Overrides:

swigReleaseOwnership in class TileDataSource

swigTakeOwnership

public void swigTakeOwnership()

Overrides:

swigTakeOwnership in class TileDataSource

swigCreatePolymorphicInstance

public static HTTPTileDataSource swigCreatePolymorphicInstance(long cPtr,
                                                               boolean cMemoryOwn)

Creates a polymorphic instance of the given native object. This is used internally by the SDK.

getBaseURL

public java.lang.String getBaseURL()

Returns the base URL template containing tags.

Returns:

The base URL template.

setBaseURL

public void setBaseURL(java.lang.String baseURL)

Sets the base URL for the data source.

Parameters:

baseURL - The base URL containing tags (for example, "http://tile.openstreetmap.org/{zoom}/{x}/{y}.png").

getHTTPHeaders

public StringMap getHTTPHeaders()

Returns the current set of HTTP headers used. Initially this set is empty and can be changed with setHTTPHeaders.

Returns:

The current set of custom HTTP headers.

setHTTPHeaders

public void setHTTPHeaders(StringMap headers)

public TileData loadTile(MapTile mapTile)

Description copied from class: TileDataSource

Loads the specified tile.

Overrides:

loadTile in class TileDataSource

Parameters:

mapTile - The tile to load.

Returns:

The tile data. If the tile is not available, null may be returned.

buildTileUrl

protected java.lang.String buildTileUrl(MapTile tile)

swigGetClassName

public java.lang.String swigGetClassName()

Returns the actual class name of this object. This is used internally by the SDK.

Overrides:

swigGetClassName in class TileDataSource

Returns:

The class name of this object.

swigGetDirectorObject

public java.lang.Object swigGetDirectorObject()

Returns the connected director object. This is used internally by the SDK.

Overrides:

swigGetDirectorObject in class TileDataSource

Returns:

The connected director object or null if director is not connected.
