Interface Serializer<T>

Type Parameters:

T - the type of the instances to serialize

All Known Implementing Classes:

CharSerializer, CompactJavaSerializer, CompactPersistentJavaSerializer, DoubleSerializer, FloatSerializer, IntegerSerializer, LongSerializer, SoftLockValueCombinedSerializer, StringSerializer

public interface Serializer<T>

Interface defining the contract used to transform types in a serial form. Implementations must be thread-safe. When used within the default serialization provider, there is an additional requirement: The implementations must define either or both of the two constructors:

• Accepting a single ClassLoader parameter: This constructor will be used to initialize the serializer for transient caches
• Accepting a ClassLoader parameter and a file based persistence context: This constructor will be used to initialize the serializer for persistent caches

.

Method Summary

boolean	equals(T object, java.nio.ByteBuffer binary) Checks if the given instance and serial form are representations of the same instance.
T	read(java.nio.ByteBuffer binary) Reconstructs an instance from the given serial form.
java.nio.ByteBuffer	serialize(T object) Transforms the given instance into its serial form.

Method Detail

serialize

java.nio.ByteBuffer serialize(T object)
                              throws SerializerException

Transforms the given instance into its serial form.

Parameters:

object - the instance to serialize

Returns:

the binary representation of the serial form

Throws:

SerializerException - if serialization fails

read

T read(java.nio.ByteBuffer binary)
       throws java.lang.ClassNotFoundException,
              SerializerException

Reconstructs an instance from the given serial form.

Parameters:

binary - the binary representation of the serial form

Returns:

the de-serialized instance

Throws:

SerializerException - if reading the byte buffer fails

java.lang.ClassNotFoundException - if the type to de-serialize to cannot be found

equals

boolean equals(T object,
               java.nio.ByteBuffer binary)
               throws java.lang.ClassNotFoundException,
                      SerializerException

Checks if the given instance and serial form are representations of the same instance.

Parameters:

object - the instance to check

binary - the serial form to check

Returns:

true if both parameters represent the same instance, false otherwise

Throws:

SerializerException - if reading the byte buffer fails

java.lang.ClassNotFoundException - if the type to de-serialize to cannot be found
