Method Detail

newInstance

public static java.lang.Object newInstance(java.lang.Class type,
                                           java.lang.Object[] dependencies)

Create an instance with dependency injection. The given dependencies are used to match the parameters of the constructors of the type. Constructors with most parameters are examinated first. A parameter type sequence matching the sequence of the dependencies' types match first. Otherwise all the types of the dependencies must match one of the the parameters although no dependency is used twice. Use a TypedNull instance to inject null as parameter.

Parameters:

type - the type to create an instance of

dependencies - the possible dependencies

Returns:

the instantiated object

Throws:

ObjectAccessException - if no instance can be generated
