Package org.palladiosimulator.edp2.repository.local.dao.internal.backgroundlist.serializer

Interface Serializer<T>

All Known Implementing Classes:
DoubleSerializer, IdentifierSerializer, LongSerializer
public interface Serializer<T>
Interface used by the BackgroundMemoryList to serialise the elements of the list into bytestreams and vice versa. The elements serialised form has to have a constant memory footprint. Otherwise using the BackgroundMemoryList will not work as it relies on the constant sizes to seek in the background storage and calculate the number of elements.

  • Method Summary

    Modifier and Type
    Method
    Description
    T[]
    deserialise(byte[] bytes)
    Convert a serialised form into an array of elements of the serialiser's type
    long
    getElementLength()
     
    byte[]
    serialise(Object[] objects, int count)
    Convert the given array of elements into their serialised form.

  • Method Details

    • getElementLength

      long getElementLength()
      Returns:
      The size of each element in serialised form, e.g., for doubles it could be 8 bytes (IEEE format). The result is not allowed to change at runtime

    • serialise

      byte[] serialise(Object[] objects, int count)
      Convert the given array of elements into their serialised form. Attention: Due to a flaw in Java Generics, this signature cannot be serialise(T[] objects, int count) as this leads to a class cast exception despite the fact that you pass the right array. We kept the Type parameter to get at least a type save deserialise.
      Parameters:
      objects - The array of elements to serialise
      count - The number of elements to serialise
      Returns:
      The elements in their serialised form

    • deserialise

      T[] deserialise(byte[] bytes)
      Convert a serialised form into an array of elements of the serialiser's type
      Parameters:
      bytes - The byte array to deserialise
      Returns:
      An array of elements deserialised from the given byte array
