        public ObjectArraySerializer​(Kryo kryo,
                                     java.lang.Class type)

      • write

        public void write​(Kryo kryo,
                          Output output,
                          java.lang.Object[] object)
        Description copied from class: Serializer
        Writes the bytes for the object to the output.

        This method should not be called directly, instead this serializer can be passed to Kryo write methods that accept a serialier.

        Specified by:
        write in class Serializer<java.lang.Object[]>
        object - May be null if Serializer.getAcceptsNull() is true.
      • read

        public java.lang.Object[] read​(Kryo kryo,
                                       Input input,
                                       java.lang.Class<java.lang.Object[]> type)
        Description copied from class: Serializer
        Reads bytes and returns a new object of the specified concrete type.

        Before Kryo can be used to read child objects, Kryo.reference(Object) must be called with the parent object to ensure it can be referenced by the child objects. Any serializer that uses Kryo to read a child object may need to be reentrant.

        This method should not be called directly, instead this serializer can be passed to Kryo read methods that accept a serialier.

        Specified by:
        read in class Serializer<java.lang.Object[]>
        Returns:
        May be null if Serializer.getAcceptsNull() is true.
      • copy

        public java.lang.Object[] copy​(Kryo kryo,
                                       java.lang.Object[] original)
        Description copied from class: Serializer
        Returns a copy of the specified object. The default implementation returns the original if Serializer.isImmutable() is true, else throws KryoException. Subclasses should override this method if needed to support Kryo.copy(Object).

        Before Kryo can be used to copy child objects, Kryo.reference(Object) must be called with the copy to ensure it can be referenced by the child objects. Any serializer that uses Kryo to copy a child object may need to be reentrant.

        This method should not be called directly, instead this serializer can be passed to Kryo copy methods that accept a serialier.

        Overrides:
        copy in class Serializer<java.lang.Object[]>
      • setElementsCanBeNull

        public void setElementsCanBeNull​(boolean elementsCanBeNull)
        Parameters:
        elementsCanBeNull - False if all elements are not null. This saves 1 byte per element if the array type is final or elementsAreSameClassAsType is true. True if it is not known (default).
      • setElementsAreSameType

        public void setElementsAreSameType​(boolean elementsAreSameType)
        Parameters:
        elementsAreSameType - True if all elements are the same type as the array (ie they don't extend the array type). This saves 1 byte per element if the array type is not final. Set to false if the array type is final or elements extend the array type (default).
      • setGenerics

        public void setGenerics​(Kryo kryo,
                                java.lang.Class[] generics)
        Description copied from class: Serializer
        Sets the generic types of the field or method this serializer will be used for on the next call to read or write. Subsequent calls to read and write must not use this generic type information. The default implementation does nothing. Subclasses may use the information provided to this method for more efficient serialization, eg to use the same type for all items in a list.
        Overrides:
        setGenerics in class Serializer<java.lang.Object[]>
        generics - Some (but never all) elements may be null if there is no generic type information at that index.
