Tips for effectively engaging with a Component's aggregationUnleash the full potential of

After configuring an aggregation for my Component, here is what it looks like:

        aggregations : {
            busyDialog : {
                type: "sap.m.BusyDialog",
                multiple: false
            }
        }

The aggregation is named "busyDialog" and can hold objects of the type "sap.m.BusyDialog".

I have the capability to retrieve the object along with its settings using 

my.ui5.namespace.Component.getMetadata().getAggregations().busyDialog

However, I am unsure about the most effective way to add an item to it or access a control that has already been added in the aggregation. Are there any methods such as "addbusyDialog" available?

I was referring to this resource:

javascriptmodel-view-controllercomponentssapui5

Answer №1

The OpenUI5 framework automatically generates different methods for handling aggregations based on the setting of multiple. When multiple is set to false, the following methods are generated for the aggregation named item:

setItem(oItem)
getItem()
destroyItem()

Conversely, when multiple is set to true, these methods are created:

addItem(oItem)
insertItem(oItem, iIndex)
getItems()
indexOfItem(oItem)
removeItem(vItem) // item or index of item
removeAllItems()
destroyItems()

If you need to manipulate the busyDialog aggregation, it's recommended to utilize the generated methods as follows:

myComponent.setBusyDialog(oBusyDialog);
myComponent.getBusyDialog();
myComponent.destroyBusyDialog();
