  • Method Details

    • transformEntry

      @Nullable public Entry transformEntry(@NotNull Entry e)
      Applies an appropriate transformation to the provided entry.
      Specified by:
      transformEntry in interface EntryTransformation
      Parameters:
      e - The entry to transform.
      Returns:
      A copy of the entry with any appropriate transformation applied, the original entry if no transformations were necessary, or null if the entry should be suppressed.

    • transformChangeRecord

      @Nullable public LDIFChangeRecord transformChangeRecord(@NotNull LDIFChangeRecord r)
      Applies an appropriate transformation to the provided LDIF change record.
      Specified by:
      transformChangeRecord in interface LDIFChangeRecordTransformation
      Parameters:
      r - The LDIF change record to transform.
      Returns:
      A copy of the change record with any appropriate transformation applied, the original change record if no transformations were necessary, or null if the change record should be suppressed.

    • translate

      @Nullable public Entry translate(@NotNull Entry original, long firstLineNumber)
      Applies some special transformation or filtering to the original Entry.
      Specified by:
      translate in interface LDIFReaderEntryTranslator
      Parameters:
      original - The original Entry that was read and parsed from the input file.
      firstLineNumber - The first line number of the LDIF record corresponding to the read Entry. This is most useful when throwing an LDIFException.
      Returns:
      The Entry that should be returned in the call to LDIFReader.readEntry(). This can be the original parameter Entry, a newly constructed Entry, or null to signal that the provided Entry should be skipped.

    • translate

      @Nullable public LDIFChangeRecord translate(@NotNull LDIFChangeRecord original, long firstLineNumber)
      Applies some special transformation or filtering to the original change record.
      Specified by:
      translate in interface LDIFReaderChangeRecordTranslator
      Parameters:
      original - The original change record that was read and parsed from the input file.
      firstLineNumber - The first line number of the LDIF change record. This is most useful when throwing an LDIFException.
      Returns:
      The LDIF change record that should be returned in the call to LDIFReader.readChangeRecord(). This can be the original parameter change record, a newly constructed change record, or null to signal that the provided change record should be skipped.

    • translateEntryToWrite

      @Nullable public Entry translateEntryToWrite(@NotNull Entry original)
      Applies some special transformation or filtering to the original Entry.
      Specified by:
      translateEntryToWrite in interface LDIFWriterEntryTranslator
      Parameters:
      original - The original Entry that was to be written.
      Returns:
      The Entry that should be written. This can be the original parameter Entry, a newly-constructed Entry, or null to signal that this Entry should not be written. Note, however, that if the original entry provided as a parameter is altered, then the change will be visible to anything that references that entry. If you are not sure about whether changes to the original entry are acceptable, it is recommended that you use the duplicate() method to create a copy of the original and make the necessary changes to that duplicate.

    • translateChangeRecordToWrite

      @Nullable public LDIFChangeRecord translateChangeRecordToWrite(@NotNull LDIFChangeRecord original)
      Applies some special transformation or filtering to the original change record.
      Specified by:
      translateChangeRecordToWrite in interface LDIFWriterChangeRecordTranslator
      Parameters:
      original - The original change record that was to be written.
      Returns:
      The change record that should be written. This can be the original parameter change record, a newly-constructed change record, or null to signal that the change record should not be written. Note, however, that if the original record provided as a parameter is altered, then the change will be visible to anything that references that change record. If you are not sure about whether changes to the original change record are acceptable, it is recommended that you use the duplicate() method to create a copy of the original and make the necessary changes to that duplicate.
