Method Detail

newInstance

public static Object newInstance(Class type,
                                 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 examined 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
