Interface Serializer<T>

Type Parameters:
T - The type of the object being serialized and deserialized.
All Known Implementing Classes:
DefaultSerializer, XmlSerializer
public interface Serializer<T>
A Serializer converts objects to raw binary data and vice versa, enabling persistent storage of objects to files, HTTP cookies, or other mechanism.

A Serializer should only do conversion, never change the data, such as encoding/decoding or encryption. These orthogonal concerns are handled elsewhere by Shiro, for example, via CodecSupport and

  • Method Summary

    Modifier and Type
    Method
    Description
    T
    deserialize(byte[] serialized)
    Converts the specified raw byte[] array back into an original Object form.
    byte[]
    serialize(T o)
    Converts the specified Object into a byte[] array.

  • Method Details

    • serialize

      byte[] serialize(T o) throws SerializationException
      Converts the specified Object into a byte[] array. This byte[] array must be able to be reconstructed back into the original Object form via the deserialize method.
      Parameters:
      o - the Object to convert into a byte[] array.
      Returns:
      a byte[] array representing the Object's state that can be restored later.
      Throws:
      SerializationException - if an error occurs converting the Object into a byte[] array.

    • deserialize

      T deserialize(byte[] serialized) throws SerializationException
      Converts the specified raw byte[] array back into an original Object form. This byte[] array is expected to be the output of a previous serialize method call.
      Parameters:
      serialized - the raw data resulting from a previous serialize call.
      Returns:
      the Object that was previously serialized into the raw byte[] array.
      Throws:
      SerializationException - if an error occurs converting the raw byte[] array back into an Object.
