  • Field Details

    • m_aExtractor

      protected ValueExtractor[] m_aExtractor
      The ValueExtractor array.

  • Constructor Details

    • AbstractCompositeExtractor

      public AbstractCompositeExtractor()
      Default constructor

    • AbstractCompositeExtractor

      public AbstractCompositeExtractor(ValueExtractor[] aExtractor)
      Construct a AbstractCompositeExtractor based on the specified ValueExtractor array.
      Parameters:
      aExtractor - the ValueExtractor array

  • Method Details

    • getExtractors

      public ValueExtractor[] getExtractors()
      Obtain the ValueExtractor array.
      Returns:
      the ValueExtractor array

    • equals

      public boolean equals(Object o)
      Compare the AbstractCompositeExtractor with another object to determine equality. If either instances have a canonical name, equality is determined by AbstractExtractor.equals(Object). Otherwise, fallback to legacy equality where two AbstractCompositeExtractor objects are considered equal iff they belong to the same class and their underlying ValueExtractor arrays are deep-equal.
      Specified by:
      equals in interface Comparator<T>
      Specified by:
      equals in interface ValueExtractor<T,E>
      Overrides:
      equals in class AbstractExtractor<T,E>
      Parameters:
      o - the reference object with which to compare
      Returns:
      true iff this AbstractCompositeExtractor and the passed object are equivalent

    • hashCode

      public int hashCode()
      Compute a hash value for the AbstractCompositeExtractor object If canonical name is non-null, return hashcode of canonical name string; otherwise, compute the hashcode as a sum of all hashCodes.
      Specified by:
      hashCode in interface ValueExtractor<T,E>
      Overrides:
      hashCode in class AbstractExtractor<T,E>
      Returns:
      an integer hash value for this ValueExtractor object

    • toString

      public String toString()
      Return a human-readable description for this ValueExtractor.
      Overrides:
      toString in class Object
      Returns:
      a String description of the ValueExtractor

    • readExternal

      public void readExternal(DataInput in) throws IOException
      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
      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
      Restore the contents of a user type instance by reading its state using the specified PofReader object.
      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

      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
