Method Detail

createInstance

public static <T> T createInstance(Object source,
                                   Class<T> base,
                                   ClassLoader classLoader)

Creates or returns an instance of an arbitrary type which is a sub type of given base class. If the source object already is an instance of base, then it is returned. If the source object is a Class object, its no-argument default constructor will be called and the resulting object returned. If the source is a String it is taken to be the full qualified name of a class which is then loaded using the given ClassLoader prior to calling its default constructor.

Parameters:

source - Either a String, a Class or a ready to use object.

base - A super type of the object to create.

classLoader - The ClassLoader that should be used to load the class in case the source parameter is a String.

Returns:

The obtained object.

Throws:

TinyPlugzException - If anything goes wrong in the process described above.
