Class DefaultClassInstantiator

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

      • newInstance

        public java.lang.Object newInstance​(java.lang.Class<?> c)
                             throws java.lang.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:
        java.lang.InstantiationException - when an error occured during instantiation

      • isSerializable

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

      • getConstructorToUse

        public java.lang.reflect.Constructor<?> getConstructorToUse​(java.lang.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
        Parameters:
        clazz - Class in which constructor is searched
        Returns:
        Constructor to use

        Get some default instances of provided classes
        Parameters:
        methodTypes - Classes to instantiate
        Returns:
        Instances of methodTypes in order
        Throws:
        java.lang.InstantiationException - Thrown if the class instantiation fails

      • getSerializedBytes
