Method Detail

getJPAZLock

public static Object getJPAZLock()

Returns the object used as synchronization lock for all JPAZ objects. In order to avoid deadlock and achieving mutual exclusion, all JPAZ objects use the only shared lock. This object should be used as a lock for each JPAZ atomic action.

Returns:

synchronization the lock object.

delay

public static void delay(long time)

Blocks the execution for a given amount of time.

Parameters:

time - the time in milliseconds.

normalizeAngleInDegrees

public static double normalizeAngleInDegrees(double angle)

Normalizes angle in degrees.

Parameters:

angle - the angle in degrees.

Returns:

the normalized angle.

setWindowsLook

public static void setWindowsLook()

Changes look-and-feel to Windows look

setJavaLook

public static void setJavaLook()

Changes look-and-feel to Java look

isWindowShakingEnabled

public static boolean isWindowShakingEnabled()

Returns whether windows shaking is enabled.

Returns:

true, if windows shaking is enabled; false otherwise.

setWindowShakingEnabled

public static void setWindowShakingEnabled(boolean windowShakingEnabled)

Sets windows shaking. If enabled, JPAZ windows are shaked after they get focus.

Parameters:

windowShakingEnabled - true, for enabled shaking; false otherwise.

isSmartLocationEnabled

public static boolean isSmartLocationEnabled()

Returns whether smart location of method invocation windows is enabled.

Returns:

true, if smart localization of method invocation windows is enabled; false otherwise.

setSmartLocationEnabled

public static void setSmartLocationEnabled(boolean smartLocationEnabled)

Sets smart location of method invocation windows

Parameters:

smartLocationEnabled - true, for enabled smart location; false otherwise.

isHeadlessMode

public static boolean isHeadlessMode()

Returns whether headless mode is enabled.

Returns:

true, if headless mode is enabled; false otherwise.

setHeadlessMode

public static void setHeadlessMode(boolean headlessMode)

Sets headless mode. The mode can be set only once.

Parameters:

headlessMode - true, to enable headless mode; false to disable.

lockHeadlessMode

public static void lockHeadlessMode()

Locks the headless mode. After invoking this method, headless mode cannot be changed.

setScreenBounds

public static void setScreenBounds(Rectangle boundingRectangle)

Defines are where JPAZ related frames/windows should be located.

Parameters:

boundingRectangle - the area defined as rectangle or null, if no restrictions are applied.

getScreenBounds

public static Rectangle getScreenBounds()

Returns area where JPAZ-related windows/frames should be located.

Returns:

the area or null, if no restrictions are applied.

getResourceAsURL

public static URL getResourceAsURL(String resourceName)

Returns URL of a resource with given name.

Parameters:

resourceName - the string specifying the resource.

Returns:

a URL object for reading the resource, or null if the resource could not be found or the invoker doesn't have adequate privileges to get the resource.

getResourceAsStream

public static InputStream getResourceAsStream(String resourceName)

Returns a resource with given name as an open InputStream

Parameters:

resourceName - the string specifying the resource.

Returns:

an input stream for reading the resource, or null if the resource could not be found.

sunDemo

public static void sunDemo()

Executes a sample code.
