Instantiates a certain quality measure class specified by argument mqName.

Parameters:

qmName - the name of the quality measure.

Returns:

a quality measure object of class mqName.

Throws:

java.lang.ClassNotFoundException - if class denoted by argument mqName is not found.

java.lang.InstantiationException - if if this Class represents an abstract class, an interface, an array class, a primitive type, or void; or if the class has no nullary constructor; or if the instantiation fails for some other reason.

java.lang.IllegalAccessException - if the class or its nullary constructor is not accessible.

java.lang.NoSuchMethodException
