        Returns whether this filter is modified from the filter object that it synchronizes with. For example, if the filter has changed from the base filter on the WebReportInstance object exposed on a parent Report Bean. Calling synchronize or undo will re-baseline, setting isModified back to false.

        Returns:
        Whether the current expression has been modified.

      • validateMetricDatatypeAllowed

        protected boolean validateMetricDatatypeAllowed​(WebOperatorNode activeNode)

      • acceptChange

        public void acceptChange()
        Description copied from interface: ExpressionBean
        Accepts the change that is currently being worked upon. The mode is set back to Default, and the active object and active operator node are set to null. This effectively makes the expression such that the undoChange method no longer does anything - it effectively means that the user accepted the single change they made.
        Specified by:
        acceptChange in interface ExpressionBean

      • undoChange

        public void undoChange()
        Description copied from interface: ExpressionBean
        Undoes the change that is currently being worked upon. If the state is Default, then nothing happens. If the state is SelectUnit, it is set back to default. Otherwise, any changes made to the active operator node or it's children since the editing operation began are undone, either by removing the active operator node (if it is new) or by rolling its state back to the state it was in when it was set as the active operator node. This will also set the mode back to default.
        Specified by:
        undoChange in interface ExpressionBean

      • synchronize

        public void synchronize()
        Description copied from interface: ExpressionBean
        Synchronizes any changes that have been made to this expression to the owner expression accessible on the WebReportInstance or WebPrompt object. This effectively means that the reset operation will no longer do anything, and that something should be done to the owner object to submit the synchronized expression to the Intelligence Server. Note that if this bean is not in Default mode, then what is synchronized is the version of the tree excluding the changes that were made to the active operator node. The changes to the active operator node are not lost, but are not propagated to the main expression either. This method will not change the edit mode of the bean.
        Specified by:
        synchronize in interface ExpressionBean

      • resetChanges

        public void resetChanges()
        Description copied from interface: ExpressionBean
        Undoes all changes since the last synchronize call. This method will ensure that the edit mode of the bean is default, and that all non-synchronized changes are undone, even if they were accepted previously via acceptChange.
        Specified by:
        resetChanges in interface ExpressionBean

      • doCollectData

        protected void doCollectData()

      • getValidationErrorInfo

        public WebBeanError getValidationErrorInfo()
        Description copied from interface: ExpressionBean

        Returns:
        Any exception which came about from the validate call.

        public boolean validateOperands​(WebNode node)
        Description copied from interface: ExpressionBean
        Returns whether the given node and its children are valid. The primary use of this is to ensure that the given node is valid within the given RW context.
        Specified by:
        validateOperands in interface ExpressionBean
        Parameters:
        node - The WebNode object which will be validated. If null is passed, then the validation will start at the root. Note that all children will be validated as well.
        Returns:
        True if the expression is valid, false if it is not.

      • isEditable

        public boolean isEditable​(WebNode node)
        Description copied from interface: ExpressionBean
        Returns whether the given node can be edited properly under the current context of the application. If this is false, then the expression should be kept as-is in the current expression context, only allowing moving and removal of the expression. Note that this does not indicate that the subexpression is invalid; instead, it only checks whether it is possible to edit the subexpression in the current context.
        Specified by:
        isEditable in interface ExpressionBean
        Parameters:
        node - The WebNode object which is being checked.
        Returns:
        True if the expression can be edited as-is, false if it cannot.
