classNameKey - the key identifying the component

Returns:

the new component

Throws:

IllegalStateException - if no name could be found which corresponds to classNameKey

IllegalArgumentException - if classNameKey is null

WWRuntimeException - if the component could not be created

getDataFileCache

public static FileCache getDataFileCache()

getMemoryCache

public static MemoryCache getMemoryCache(String key)

getMemoryCacheSet

public static MemoryCacheSet getMemoryCacheSet()

getNetworkStatus

public static NetworkStatus getNetworkStatus()

getRetrievalService

public static RetrievalService getRetrievalService()

getStringValue

hasKey

public static boolean hasKey(String key)

isOfflineMode

public boolean isOfflineMode()

Indicates whether World Wind will attempt to connect to the network to retrieve data or for other reasons.

Returns:

NetworkStatus

removeKey

public static void removeKey(String key)

removePropertyChangeListener

public static void removePropertyChangeListener(PropertyChangeListener listener)

removePropertyChangeListener

public static void removePropertyChangeListener(String propertyName,
                                                PropertyChangeListener listener)

setOfflineMode

public void setOfflineMode(boolean offlineMode)

Parameters:

offlineMode - true if World Wind should use the network, false otherwise

See Also:

NetworkStatus

setValue

public static void setValue(String key,
                            String value)

shutDown

public static void shutDown()

Reinitialize World Wind to its initial ready state. Shut down and restart all World Wind services and clear all World Wind memory caches. Cache memory will be released at the next JVM garbage collection.

Call this method to reduce World Wind's current resource usage to its initial, empty state. This is typically required by applets when the user leaves the applet page.

World Wind can continue to be used after calling this method. The state of any existing World Wind drawables is subsequently indeterminate and they should be disposed.
