Method Details
-
getInstance
Returns or creates a new SerializerHelper. When a new instance is created by this method, all known SerializeMethods are registered.- Returns:
- the SerializerHelper singleton instance.
-
registerMethod
Registers a new SerializeMethod with this SerializerHelper.- Parameters:
method
- the method that should be registered.
-
unregisterMethod
Deregisters a new SerializeMethod with this SerializerHelper.- Parameters:
method
- the method that should be deregistered.
-
writeObject
Writes a serializable object description to the given object output stream. This method selects the best serialize helper method for the given object.- Parameters:
o
- the to be serialized object.out
- the outputstream that should receive the object.- Throws:
IOException
- if an I/O error occured.
-
isSerializable

- the generated object.
- Throws:
