static void	initializeEngine() Initialize the ArcObjects for Java with options optimal for usage in a ArcGIS Engine
static void	initializeVisualBeans() Initialize ArcObjects for Java with options optimal for using visual Java Beans in ArcGIS Engine.
static void	release(Object anObject) Release a specific reference to a COM object.
static void	releaseAll() Release all outstanding references to COM objects.
static void	releaseAllInCurrentThread() Tell the runtime to release all objects used in the current thread since the last 'trackObjectsInCurrentThread' call.
void	setBeanUsage(boolean beanUsage) Indicates whether visual ArcObjects for Java beans are used
static void	setDefault(String domain, String user, String password) Set the authentification to be used by default if none is specified when creating or using a ArcObjects Java component
void	setEngineUsage() Sets the default usage for using the ArcGIS ArcObjects for Java.
void	setNativeMode(boolean nativeMode) Indicates whether native mode is used.
void	setShutdownHook(boolean shutdownHook) Causes the runtime to release COM references when the JVM shuts down normally like when Ctrl- C is pressed

isInitVisualBeans

public static boolean isInitVisualBeans

noMTASTACommunication

public static boolean noMTASTACommunication

setVersion

public static boolean setVersion

Method Detail

setBeanUsage

public void setBeanUsage(boolean beanUsage)

Indicates whether visual ArcObjects for Java beans are used

Parameters:

beanUsage - set to true if visual ArcEngine java beans are to be used

setNativeMode

public void setNativeMode(boolean nativeMode)

Indicates whether native mode is used.

Parameters:

nativeMode - set to true if native mode is to be used.

setShutdownHook

public void setShutdownHook(boolean shutdownHook)

Causes the runtime to release COM references when the JVM shuts down normally like when Ctrl- C is pressed

Parameters:

shutdownHook - set to true if shutdownHook is to be enabled.

setEngineUsage

public void setEngineUsage()

Sets the default usage for using the ArcGIS ArcObjects for Java. Note that this method only sets the options for initialization, but init() method should be called to actually initialize the ArcObjects for Java with these options

init

public void init()

Initialize the ArcObjects for Java with options set previously by calling setXxx() methods.

initializeEngine

public static void initializeEngine()

Initialize the ArcObjects for Java with options optimal for usage in a ArcGIS Engine

initializeVisualBeans

public static void initializeVisualBeans()

Initialize ArcObjects for Java with options optimal for using visual Java Beans in ArcGIS Engine. This method includes all the optimization parameters in initializeEngine

setDefault

public static void setDefault(String domain,
                              String user,
                              String password)

Set the authentification to be used by default if none is specified when creating or using a ArcObjects Java component

Parameters:

domain - - the domain to be used when authenticating using default authentification

user - - the user to be used when authenticating using default authentification

password - - the password to be used when authenticating using default authentification

release

public static void release(Object anObject)

Release a specific reference to a COM object.

releaseAll

public static void releaseAll()

Release all outstanding references to COM objects.

releaseAllInCurrentThread

public static void releaseAllInCurrentThread()

Tell the runtime to release all objects used in the current thread since the last 'trackObjectsInCurrentThread' call.

trackObjectsInCurrentThread

public static void trackObjectsInCurrentThread()

Tell the runtime to remember all objects used in the current thread.
