Return the implementation of a feature.

Parameters:

feature - to be implemented.

Returns:

the implementation, or null if the feature has no implementation as is the case for a normal model feature

Throws:

java.lang.ClassNotFoundException - if the implementation class realising the implementation is not loadable

java.lang.NoSuchFieldException - if the implementation class realising the implementation does not provide a static INSTANCE field

java.lang.SecurityException - if the implementation class is not accessible

java.lang.IllegalAccessException - if the implementation class is not accessible

java.lang.IllegalArgumentException - if the implementation class is not accessible
