    • extract

      public Fragment<T> extract(T target)
      Description copied from interface: ValueExtractor
      Extract the value from the passed object. The returned value may be null. For intrinsic types, the returned value is expected to be a standard wrapper type in the same manner that reflection works; for example, int would be returned as a java.lang.Integer.
      Specified by:
      extract in interface ValueExtractor<T, Fragment<T>>
      Overrides:
      extract in class AbstractExtractor<T, Fragment<T>>
      Parameters:
      target - the object to extract the value from
      Returns:
      the extracted value; null is an acceptable value

    • getExtractors

      public List<ValueExtractor<? super T, ?>> getExtractors()
      Obtain the underlying extractors.
      Returns:
      the extractors

    • readExternal

      public void readExternal(DataInput in) throws IOException
      Description copied from interface: ExternalizableLite
      Restore the contents of this object by loading the object's state from the passed DataInput object.
      Specified by:
      readExternal in interface ExternalizableLite
      Parameters:
      in - the DataInput stream to read data from in order to restore the state of this object
      Throws:
      IOException - if an I/O exception occurs

    • writeExternal

      public void writeExternal(DataOutput out) throws IOException
      Description copied from interface: ExternalizableLite
      Save the contents of this object by storing the object's state into the passed DataOutput object.
      Specified by:
      writeExternal in interface ExternalizableLite
      Parameters:
      out - the DataOutput stream to write the state of this object to
      Throws:
      IOException - if an I/O exception occurs

    • readExternal

      public void readExternal(PofReader in) throws IOException
      Description copied from interface: PortableObject

      Specified by:
      readExternal in interface PortableObject
      Parameters:
      in - the PofReader from which to read the object's state
      Throws:
      IOException - if an I/O error occurs

    • writeExternal

      public void writeExternal(PofWriter out) throws IOException
      Description copied from interface: PortableObject
      Save the contents of a POF user type instance by writing its state using the specified PofWriter object.
      Specified by:
      writeExternal in interface PortableObject
      Parameters:
      out - the PofWriter to which to write the object's state
      Throws:
      IOException - if an I/O error occurs
