public static Object createComponent(String className)
                              throws WWRuntimeException

Parameters:

className - the full name, including package names, of the component to create

Returns:

the new component

Throws:

WWRuntimeException - if the Object could not be created

IllegalArgumentException - if className is null or zero length

createConfigurationComponent

public static Object createConfigurationComponent(String classNameKey)
                                           throws IllegalStateException,

Parameters:

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

getDataFileStore

public static FileStore getDataFileStore()

getLocalRetrievalService

public static RetrievalService getLocalRetrievalService()

getMemoryCache

public static MemoryCache getMemoryCache(String key)

getMemoryCacheSet

hasKey

public static boolean hasKey(String key)

isOfflineMode

public static boolean isOfflineMode()

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

Returns:

true if World Wind is in off-line mode, false if not.

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 static void setOfflineMode(boolean offlineMode)

Indicate whether World Wind should attempt to connect to the network to retrieve data or for other reasons. The default value for this attribute is false, indicating that the network should be used.

Parameters:

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

                            Object value)

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.

The state of any open WorldWindow objects is indeterminate subsequent to invocation of this method. The core WorldWindow objects attempt to shut themselves down cleanly during the call, but their resulting window state is undefined.

World Wind can continue to be used after calling this method.
