Interface Reflection.Constructor

Enclosing class:

Reflection

public static interface Reflection.Constructor

This interface represents a run-time constructor obtained through reflection. Here are few examples of utilization:

 // Default constructor (fastList = new FastList())
 Reflection.Constructor fastListConstructor
     = Reflection.getInstance().getConstructor("javolution.util.FastList()");
 Object fastList = fastListConstructor.newInstance();

 // Constructor with arguments (fastMap = new FastMap(64))
 Reflection.Constructor fastMapConstructor
     = Reflection.getInstance().getConstructor("javolution.util.FastMap(int)");
 Object fastMap = fastMapConstructor.newInstance(new Integer(64));
