Serializer

org.apache.shiro.io

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 CipherServices.

Instance Methods

Abstract Methods
Modifier and Type	Method and 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 Detail
  - 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 occurrs 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 occurrs converting the raw byte[] array back into an Object.
