Interface EclibItemContainer

public interface EclibItemContainer
Accepts and store data from user input, external system, and so on.

This is an interface, not a class because record can be customized according to the specification of page templates. Each record in apps always extends EclibRecord or its extended class, so interface is needed to customize records.
At that time in that interface you want to record feature like getItems(), but if this is a class it can't be used.

It is frequently validated with jakarta validation. So it should have features below.

  • To resolve item name from propertyPath. getItems() is used for it.
    It's used especially for error message to users.
