ERXPartial (Project Wonder Reference Documentation)

java.lang.Object
- er.extensions.partials.ERXPartial<T>

Type Parameters:

T - the EO class that this is a partial of

All Implemented Interfaces:

Serializable
```
public class ERXPartial<T extends ERXGenericRecord>
extends Object
implements Serializable
```
For overview information on partials, read the package.html in er.extensions.partials.
ERXPartial is the superclass of all partial entity implementations. ERXPartial is not itself an EO, but is acts as a partial typesafe wrapper around an existing base EO (which must extend ERXPartialGenericRecord). For instance, the base entity might be Person, but the partial may be CalendarPerson which might expose methods like calendarPerson.scheduledEvents().
To obtain a partial, you request an instance from a base EO. Take the Person example from above. You can access the interface of the CalendarPerson partial in two ways:
```
 Person person = ...;
 CalendarPerson calendarPerson = person.partialForClass(CalendarPerson.class);
 
```
or
```
 Person person = ...;
 CalendarPerson calendarPerson = person.valueForKey("@CalendarPerson");
 
```
which allows easy use of the partial entities in component bindings, like person.@CalendarPerson.scheduledEvents.
