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.

Returns true if Select Elements option can be used for the attribute

Returns the active object, the object being qualified upon. This will be null if the mode is SelectUnit or Default, or if the active operator node is set incorrectly.

Returns the current active operator node key. Note that this will not be a valid value if the mode is SelectUnit or Default.

Returns properly initialized element source for a given attribute.

Returns the internal expression object. This expression can be used to make changes to the structure of the expression.

Returns the expression bean type, from EnumExpressionBeanType.

Returns the current expression edit mode of the bean, from EnumExpressionEditMode. This represents the current state of the bean.

Returns a Scrollable interface, which can be used to set the incremental fetch window for an attribute elements qualification.

Returns the match case flag, used in searching element browsing request.

Returns the unit(attribute form/metric) used on the Right Hand Side(RHS) of the filter comparison

Returns the search pattern that will be applied to any element browsing request.

This can hold a validation error which came about from the validate call.

Returns whether the Expression bean is editable.

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.

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.

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.

Sets the current active operator node key. The isNew variable must be passed in correctly - if the node is newly created, isNew should be true, if it already existed before this edit operation, it should be false. If isNew is incorrect, then the undoChange method will not work properly.

Sets the ExpressionBeanContext. If this is set, then the expression bean will obtain the original expression that is being edited from that context.

Sets the current expression edit mode of the bean, from EnumExpressionEditMode. Note that this operation is only valid if moving between SelectUnit and Default, or from one node editing mode to another.

Sets whether the expression bean is editable.

Sets the match case flag, which determines whether the user search pattern must match case or not.

Set the unit(attribute form/metric) used on the Right Hand Side(RHS) of the filter comparison

Sets the search pattern that will be applied to any element browsing request.

This method is used to decide what Attribute subexpression to create in a given context. It returns true if getting list of available elements for a given attribute will be chip, for example because corresponding data set is already executed and cached.

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.

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.

Attempts to perform validation on the expression. Returns false and sets the validation error (retrievable via the getValidationErrorInfo} method.

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.
