Operation that allows the user to create a new instance of the given class The identifier of the Constructor to be used includes the class and constructor names, being the constructor a full description of its signature including the types of each parameter.

For example, if we want to invoke the constructor Foo(String name, int age) which belongs to Class org.bar.Foo, then the identifier of the method will be "Foo(String,int)"

Parameters:

identifier - the unique identifier for the constructor to be invoked

args - the arguments used to invoke the given Constructor

Returns:

a new instance of the given class

Throws:

ClassNotFoundModuleException - if the given class is not found in the current context

NoSuchConstructorModuleException - if the given class does not declare a constructor with the given signature

ArgumentMismatchModuleException - if the method requires a different set of arguments than the ones provided

InvocationModuleException - if an error occurs during the execution of the method

NonInstantiableTypeModuleException - if the given class is not instantiable
