Class DefaultClassInstantiator

java.lang.Object
org.easymock.internal.DefaultClassInstantiator
All Implemented Interfaces:
IClassInstantiator
public class DefaultClassInstantiator extends Object implements IClassInstantiator
Default class instantiator that is pretty limited. It just hope that the mocked class has a public empty constructor.

    • EMPTY

      private static final Class<?>[] EMPTY

  • Constructor Details

    • DefaultClassInstantiator

      public DefaultClassInstantiator()

  • Method Details

    • newInstance

      public Object newInstance(Class<?> c) throws InstantiationException
      Try to instantiate a class without using a special constructor. See documentation for the algorithm.
      Specified by:
      newInstance in interface IClassInstantiator
      Parameters:
      c - Class to instantiate
      Returns:
      new instance of clazz
      Throws:
      InstantiationException - when an error occured during instantiation

    • isSerializable

      private boolean isSerializable(Class<?> clazz)
      Tells if the provided class is serializable
      Parameters:
      clazz - Class to check
      Returns:
      If the class is serializable

    • getConstructorToUse

      public Constructor<?> getConstructorToUse(Class<?> clazz)
      Return the constructor considered the best to use with this class. Algorithm is: No args constructor and then first constructor defined in the class

      clazz - Class in which constructor is searched
      Returns:
      Constructor to use

      Parameters:
      methodTypes - Classes to instantiate
      Returns:
      Instances of methodTypes in order
      Throws:
      InstantiationException - Thrown if the class instantiation fails
