Entity types

An entity is a type of object that is constructed from the data model configuration files. Like other types of objects, entities have data in the form of object properties, and actions in the form of object domain methods.

Some Guidewire API methods take an argument of type IEntityType. The IEntityType type is an interface, not a class. All Guidewire entity types implement this interface. To use an API that requires an IEntityType, pass an entity instance to the API. For example, to pass an Address to an API that takes an IEntityType as the method argument, use code such as:

myClass.myMethod(Address)

In rare cases, you might need to get the type from an entity dynamically, for example to get the subtype of an entity instance. If you have a reference to an entity instance, get its Type property. For example, if you have a variable ad that contains an Address entity instance, use code such as the following:

myClass.myMethod(ad.Type)

Warning: The base configuration includes visible usages of the entity instance method setFieldValue. The setFieldValue method is reserved for Guidewire internal use. Calling this method can cause serious data corruption or errors in application logic that may not be immediately apparent. You must obtain explicit prior approval from Guidewire Support to call setFieldValue as part of a specific approved workaround.

Keys of Guidewire entity instances

Key is a Guidewire data model entity base type that uniquely identifies an entity instance. The internal ID property of an entity such as Policy.ID has type Key. Provide the ID of an entity instance in methods that use Key objects as parameters.

Do not confuse a key, which has the type Key, and a typekey, which has the type Typekey.

Example

var id = myEntityInstance.ID // id has type Key
