Class DefaultClassInstantiator

java.lang.Object

org.easymock.internal.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.

Method Detail

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

getArgsForTypes

public java.lang.Object[] getArgsForTypes(java.lang.Class<?>[] methodTypes)
                                   throws java.lang.InstantiationException

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

private static byte[] getSerializedBytes(java.lang.Class<?> clazz)
                                  throws java.io.IOException

Throws:

java.io.IOException

getSerializableUID

private static java.lang.Long getSerializableUID(java.lang.Class<?> clazz)

callLongMethod

private static java.lang.Long callLongMethod(java.lang.Class<?> clazz,
                                             java.lang.String methodName)

readObject

private static java.lang.Object readObject(byte[] bytes)
                                    throws java.io.IOException,
                                           java.lang.ClassNotFoundException

Throws:

java.io.IOException

java.lang.ClassNotFoundException
