Class ByteBuddyCrossClassLoaderSerializationSupport.MockitoMockObjectInputStream
- All Implemented Interfaces:
Closeable
,DataInput
,ObjectInput
,ObjectStreamConstants
,AutoCloseable
- Enclosing class:
- ByteBuddyCrossClassLoaderSerializationSupport
ObjectInputStream
that will resolve the Mockito proxy class.
This specifically crafted ObjectInoutStream has the most important role to resolve the Mockito generated
class. It is doing so via the resolveClass(ObjectStreamClass)
which looks in the stream
for a Mockito marker. If this marker is found it will try to resolve the mockito class otherwise it
delegates class resolution to the default super behavior.
The mirror method used for serializing the mock is ByteBuddyCrossClassLoaderSerializationSupport.MockitoMockObjectOutputStream.annotateClass(Class)
.
When this marker is found, ByteBuddyMockMaker.createMockType(MockCreationSettings)
methods are being used
to create the mock class.

Method Details

resolveClass
Resolve the Mockito proxy class if it is marked as such.Uses the fields
typeToMock
andextraInterfaces
to create the Mockito proxy class as theObjectStreamClass
doesn't carry useful information for this purpose.- Overrides:
resolveClass
in classObjectInputStream
- Parameters:
desc
- Description of the class in the stream, not used.- Returns:
- The class that will be used to deserialize the instance mock.
- Throws:
IOException
ClassNotFoundException
-
hackClassNameToMatchNewlyCreatedClass
private void hackClassNameToMatchNewlyCreatedClass(ObjectStreamClass descInstance, Class<?> proxyClass) throws ObjectStreamException Hack thename
field of the givenObjectStreamClass
with thenewProxyClass
. The parent ObjectInputStream will check the name of the class in the stream matches the name of the one that is created in this method. The CGLIB classes uses a hash of the classloader and/or maybe some other data that allow them to be relatively unique in a JVM. When names differ, which happens when the mock is deserialized in another ClassLoader, ajava.io.InvalidObjectException
is thrown, so this part of the code is hacking through the givenObjectStreamClass
to change the name with the newly created class.- Parameters:
descInstance
- TheObjectStreamClass
that will be hacked.proxyClass
- The proxy class whose name will be applied.- Throws:
InvalidObjectException
ObjectStreamException
-
notMarkedAsAMockitoMock
Read the stream class annotation and identify it as a Mockito mock or not.- Parameters:
marker
- The marker to identify.- Returns:
true
if not marked as a Mockito,false
if the class annotation marks a Mockito mock.
