Method Detail

getCsvFormatExampleString

public String getCsvFormatExampleString()

Sometimes, it is easier to understand the format by looking at an example.

When the type item list source CHARACTER_SEPARATED_VALUES is selected: Gets a formatted string of values using the currently selected format settings. When the string returned by this method is split into individual values using the current format settings, this results in the list of example values.

Returns:

The list of example values, formatted according to the current settings.

getCsvFormatExampleValues

public List<String> getCsvFormatExampleValues()

Sometimes, it is easier to understand the format by looking at an example.

When the type item list source CHARACTER_SEPARATED_VALUES is selected: Gets a list of example values. The example string is the formatted string, this method returns the values obtained when splitting that formatted string according to the current format settings.

Returns:

A list of sample values for illustrating the currently selected format.

getItemSource

public EForEachLoopItemListSource getItemSource()

Gets the source from which to obtain the items over which to iterate.

Returns:

The source from which to obtain the items over which to iterate.

setItemSource

public void setItemSource(EForEachLoopItemListSource newItemSource)

Sets the source from which to obtain the items over which to iterate.

Parameters:

newItemSource - The source from which to obtain the items over which to iterate.

prepareViewForElement

public void prepareViewForElement(IElementPropInitParams<FcForEachLoopProps> params)
                           throws Exception

Description copied from interface: IElementPropertiesBean

Called each time when the properties panel for a certain workflow element is loaded. This method is passed the workflow element and the properties model, and should perform whatever initialization is necessary in order for the user to start editing the properties.

Specified by:

prepareViewForElement in interface IElementPropertiesBean<FcForEachLoopProps,WorkflowNode>

Parameters:

params - The current element to be edited and its properties. You may store a reference to these, modify them, and return them when IElementPropertiesBean.retrieveCurrentProperties(Object) is called.

Throws:

Exception - When the initialization failed. If an exception is thrown, the user is shown an error indicating that the properties cannot be edited.

retrieveCurrentProperties

public IRetrieveElementPropsRetVal<FcForEachLoopProps> retrieveCurrentProperties(FcForEachLoopProps storedModel)

Description copied from interface: IElementPropertiesBean

Called each time the data that is currently being edited needs to be retrieved, and possibly persisted. Usually this is called when the user switch to another workflow element, or when the

Note, however, that you may not assume the editing process for the current workflow element is done. The data is sometimes retrieved while the user is still editing the properties, such as to sync the properties with the workflow design area. Do not perform any clean up work here. Use PreDestroy for cleanup.

Specified by:

retrieveCurrentProperties in interface IElementPropertiesBean<FcForEachLoopProps,WorkflowNode>

Specified by:

retrieveCurrentProperties in interface INodePropertiesBean<FcForEachLoopProps>

Parameters:

storedModel - The same model that was passed to IElementPropertiesBean.prepareViewForElement(IElementPropInitParams). If you did not need to replace that model with another instance, you can just returned it. Conversely, if you did store the properties model in your bean, you may just return your stored value and ignore this parameter altogether.

Returns:

The current properties that reflect the current user input. You may mutate and return the same object(s) that were passed to IElementPropertiesBean.prepareViewForElement(IElementPropInitParams).

updateCurrentProperties

public void updateCurrentProperties(IElementUpdateCurrentPropsParams<FcForEachLoopProps> params)
                             throws Exception

Description copied from interface: IElementPropertiesBean

Called each time when the data of the selected node was edited externally. Normally this does not happen. This only happens when the element handler returned a custom client handler (see IElementHandler.getJavaScript(boolean)) that invoked an external custom params update from the flowchart. If this bean stored the data in a field during IElementPropertiesBean.prepareViewForElement(IElementPropInitParams), it should update that field.

Specified by:

updateCurrentProperties in interface IElementPropertiesBean<FcForEachLoopProps,WorkflowNode>

Parameters:

params - Params with the old and new data.

Throws:

Exception - When the data could not be updated. This exception is caught and an error message is shown to the user.
