Class PropertyBag

java.lang.Object

org.identityconnectors.test.common.PropertyBag

public final class PropertyBag
extends Object

Encapsulates a read-only bag of properties, which can be accessed in a type-safe manner.

The simplest way to obtain a required (i.e., the property must be in the bag, otherwise an exception is thrown) property value is getProperty(String, Class). If the property is not a required one, the getProperty(String, Class, Object) method can be used, which also takes a default value which is returned when the property is not present in the bag.

Method Summary

<T> T	getProperty(String name, Class<T> type, T def)	Gets a property value, returning a default value when no property with the specified name exists in the bag.
