• getPrettyLocaledTexts

  PrettyLocaledTexts getPrettyLocaledTexts()

  Gets the locale'd texts instance for the sessions language and text tables.

• getRuntimePropFromReference

  GProp<?> getRuntimePropFromReference​(java.lang.String reference)

  Gets a reference for runtime use to get the reference of an item. The reference must be fully qualified such as "*ALIAS:/type/path" or "MODULE:/type/path" and cannot be relative.

  Note: The reference can be to the static or virtualized properties, but if a property type is virtualized and the property is not found, a fall-back to search the application for the static non-virtualized property IS NOT PERFORMED.

  Calling this method is the same as calling getRuntimePropFromReference(reference, false)}.

  Parameters:

  reference - The reference to look-up.

  Returns:

  The property found, or null for reference not found.

• getRuntimePropFromReference

  GProp<?> getRuntimePropFromReference​(java.lang.String reference,
                                       boolean fallBackToNonVirtualized)

  Gets a reference for runtime use to get the reference of an item. The reference must be fully qualified such as "*ALIAS:/type/path" or "MODULE:/type/path" and cannot be relative.

  If the flag fallBackToNonVirtualized is false, the search will not fallback to searching for the non-virtualized property in the runtime app. The result will only returned virtualized properties, i.e. for a reference as e.g. "module:/vs/someVS", and depending on where this method is called (the client session), also includes other virtualized properties such as panels as e.g. "module:/panel/somePanel".

  To always fallback to also searching the runtime app, specify fallBackToNonVirtualized to true.

  Parameters:

  reference - The reference to look-up.

  fallBackToNonVirtualized - Flag indicating a fallback to non-virtualized properties.

  Returns:

  The property found, or null for reference not found.

• getRootFromName

  PropCnr getRootFromName​(GProp<?> requestor,
                          java.lang.String module)

  Gets the module root for a name. In the Editor, the module is the project, and that root container is returned. In the Server, the module doesn't matter, so the real root returns itself.

  When running with assertions, this call throws an assertion error by default, showing that the call is directed to a non-root property container.

  Parameters:

  requestor - The requestor property.

  module - The module name (without colon), i.e. the project name in the Designer.

  Returns:

  The root property container, or null if this container is not the root, or if the module name is not found. The default implementation returns null.

• getClientSessionsCount

  int getClientSessionsCount()

  Gets the count of client sessions.

• getClientSessionGyros

  IClientSessionGyro[] getClientSessionGyros()

  The array of active client session Gyro's.

• requestUILock

  ILockState requestUILock()

  Note: You MUST call the objects {link @ILockState#release()} method to release the lock state.

  Returns:

  The lock state object.

• isUILocked

  boolean isUILocked()

  Get the current UI lock state.

  You may also query the incremental lock state using getLockCount().

  Returns:

• lockUI

  boolean lockUI​(KString waitMsg,
                 ProgressIndicatorDelay delay)

  Locks the UI with a message and a delay.

  Consider using the method requestUILock() to handle UI locking along with optional message, wait delay and progress indicator.

  This call will not change the potential wait message or wait message delay if the method is not successful.

  Also consider using the method decrementUILock() in case multiple operations and threads can toggle the lock state.

  Parameters:

  waitMsg - The wait message, null for none.

  delay - Delay before the message is shown in the Client.

  Returns:

  Busy change flag, true if busy state changed, false otherwise. The return value may be false because the lock count is non-zero.

• lockUI

  boolean lockUI​(KString waitMsg,
                 int delay)

  Locks the UI with a message and a delay.

  Consider using the method requestUILock() to handle UI locking along with optional message, wait delay and progress indicator.

  This call will not change the potential wait message or wait message delay if the method is not successful.

  Also consider using the method decrementUILock() in case multiple operations and threads can toggle the lock state.

  Parameters:

  waitMsg - The wait message, null for none.

  delay - Delay of lock spinner: -2 for default (1.5 second), -1 disabled, 0=no delay, >0 wait time in milliseconds (1-20000, i.e. 20 seconds).

  Returns:

  Busy change flag, true if busy state changed, false otherwise. The return value may be false because the lock count is non-zero.

  Throws:

  java.lang.IllegalArgumentException - If the delay value is not -1 to 20000 (20 seconds).

• unlockUI

  boolean unlockUI()

  Unlocks the UI.

  Consider using the method requestUILock() to handle UI locking along with optional message, wait delay and progress indicator.

  This call will not change the potential wait message or wait message delay if the method is not successful.

  Also consider using the method decrementUILock() in case multiple operations and threads can toggle the lock state.

  Returns:

  Busy change flag, true if busy state changed, false otherwise. The return value may be false because the lock count is non-zero.

• getLockCount

  int getLockCount()

  Returns:

  The lock count, zero or positive value.

• incrementUILock

  int incrementUILock()

  Increases the incremental lock state. If it was zero, it will UI lock the session. Each call to this method must match a call to decrementUILock().

  Consider using the method requestUILock() to handle UI locking along with optional message, wait delay and progress indicator.

  Returns:

  The lock count, i.e. the number of calls that has been made to this method minus the number of calls to decrementUILock(), after the call to this method.

• decrementUILock

  int decrementUILock()

  Decreases the incremental lock state. If it becomes zero, it will UI unlock the session. Each call to this method must match a call to incrementUILock().

  If this method is called and the lock count is zero, nothing will happen, but a warning event with a call stack will be logged.

  Parameters:

  component - A VS component.

  Returns:
