public class ServerMapTileFactory extends StandardMapTileFactory implements MapTileFactory, PropertyConsumer
# Inherited from StandardMapTileFactory rootDir=the URL to the parent directory of the tiles on a server. The factory will construct specific file paths that are appended to this value. fileExt=the file extension to append to the tile names, should have a period. cacheSize=the number of mapTiles the factory should hold on to. The default is 100. # Additional properties localCacheRootDir=if specified, the factory will store tiles locally at this root directory. This directory is checked before going to the server, too.

protected java.lang.String |
buildCacheKey(int x,
int y,
int z,
java.lang.String fileExt)
Creates a unique cache key for this tile based on zoom, x, y.
|
java.lang.String |
buildLocalFilePath(int x,
int y,
int z,
java.lang.String fileExt)
Acts the same as the buildFilePath method, but works for a local
directory specified in the properties.
|
java.lang.Object |
getFromCache(java.lang.Object key,
int x,
int y,
int zoomLevel)
An auxiliary call to retrieve something from the cache, modified to allow
load method to do some projection calculations to initialize tile
parameters.
|
byte[] |
getImageBytes(java.lang.String imagePath,
java.lang.String localFilePath)
Tries to get the image bytes from imagePath URL.
|
java.util.Properties |
getProperties(java.util.Properties getList)
Method to fill in a Properties object, reflecting the current
values of the PropertyConsumer.
|
java.util.Properties |
getPropertyInfo(java.util.Properties list)
Method to fill in a Properties object with values reflecting
the properties able to be set on this PropertyConsumer.
|
CacheObject |
load(java.lang.Object key,
int x,
int y,
int zoomLevel,
Projection proj)
Checks the local directory first for a locally cached version of the tile
before going off to the server.
|
void |
setProperties(java.lang.String prefix,
java.util.Properties setList)
Method to set the properties in the PropertyConsumer.
