Interface Factory

All Known Implementing Classes:

AbstractFactory, JavaFactory, ModelFactory

public interface Factory

Factory is the abstract interface satisfied by concrete object factories. A Factory is a utility for synthesising run-time object instances from the text description of their value and type. The main functionality provided by a Factory is the method createObject(), which creates any kind of Object, given a description of its value and its type.

Method Summary

Methods

Modifier and Type	Method and Description
<T> T	create(java.lang.String value, java.lang.String type) Creates a strongly-typed instance of any kind of Java Object with the given printed representation and Java type.
java.lang.Object	createObject(java.lang.String value, java.lang.String type) Creates an instance of any type of Object, with the given value.

Method Detail

create

<T> T create(java.lang.String value,
           java.lang.String type)

Creates a strongly-typed instance of any kind of Java Object with the given printed representation and Java type. Performs an unchecked type cast on the result of createObject(). Provided for convenience.

Type Parameters:

T - the returned object type.

Parameters:

value - the value, as a String.

type - the Java type, as a String.

Returns:

a new instance of the type.

createObject

java.lang.Object createObject(java.lang.String value,
                            java.lang.String type)

Creates an instance of any type of Object, with the given value. This is the principal factory method, but is abstract, to allow subclasses to decode type strings styled in different formats.

Parameters:

value - the value, as a String.

type - the type, as a String.

Returns:

a new instance of the type.
