Method Detail

write

public static void write(java.lang.Object target,
                         java.lang.String propertyName,
                         java.lang.Object value)

Updates the property of the target object.

---

smartWrite

public static void smartWrite(java.lang.Object target,
                              java.lang.String propertyName,
                              java.lang.String value)

An improved version of write(Object, String, Object) 55 where the value starts as a string and is converted to the correct property type before being assigned.

Since:

1.1

---

configureProperties

public static void configureProperties(java.lang.Object target,
                                       java.lang.String initializer)

Initializes the properties of an object from a string. The string is a comma-seperated sequence of property names and values. Property names are seperated from values be an equals sign. Spaces before and after the property names are trimmed. For boolean properties, the equals sign and value may be omitted (a value of true is assumed), or the property name may be prefixed with an exclamation point to indicated false value. Example: validate,maxLength=10,displayName=User Id.

Since:

1.1
