Interface Serializer<T>

  • Type Parameters:
    T - a type of serializable object
    All Known Implementing Classes:
    CheckingSerializerDecorator
    public interface Serializer<T>
    Converts Java objects into a binary representation in some format, and vice versa.

    Implementations must ensure that for any object o, toBytes(Object) produces such an array, that being passed to fromBytes(byte[]), is converted to another object o2, that is equal to the original object o.

    This interface is designed to be primarily used by storage proxies and proof validators.

        Parameters:
        value - a value to serialize, must not be null
        Returns:
        a byte array containing a serialized value
        Throws:

      • fromBytes

        T fromBytes​(byte[] serializedValue)
        De-serializes a value from a given byte array.
        Parameters:
        serializedValue - an array containing a serialized value of type T, must not be null
        Returns:
        a value
        Throws:
