      • getRuntimePropFromReference

        public 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)}.

        Specified by:
        getRuntimePropFromReference in interface IAppSessionGyro
        Specified by:
        getRuntimePropFromReference in interface IRuntimeReferenceLookup
        Parameters:
        reference - The reference to look-up.
        Returns:
        The property found, or null for reference not found.
      • getRuntimePropFromReference

        public 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.

        Specified by:
        getRuntimePropFromReference in interface IAppSessionGyro
        Specified by:
        getRuntimePropFromReference in interface IRuntimeReferenceLookup
        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.

                                       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.

        Specified by:
        getRootFromName in interface IAppSessionGyro
        Specified by:
        getRootFromName in interface IRuntimeReferenceLookup

        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.

        lockUI in interface IAppSessionGyro
        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.

        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.

        Specified by:
        unlockUI in interface IAppSessionGyro
        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

        public int getLockCount()
        Returns the incremental lock count that governs the UI locking state. Note that the lock state may be in effect even if the lock count is zero.
        Specified by:
        getLockCount in interface IAppSessionGyro
        Returns:
        The lock count, zero or positive value.
      • incrementUILock

        public 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.

        Specified by:
        incrementUILock in interface IAppSessionGyro
        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

        public 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.

        Specified by:
        decrementUILock in interface IAppSessionGyro
        Returns:
        The lock count, i.e. the number of calls that has been made to incrementUILock() minus the number of calls to this method.
