Class ExcludeAttributeTransformation

java.lang.Object

com.unboundid.ldap.sdk.transformations.ExcludeAttributeTransformation

All Implemented Interfaces:

EntryTransformation, LDIFChangeRecordTransformation, LDIFReaderChangeRecordTranslator, LDIFReaderEntryTranslator, LDIFWriterChangeRecordTranslator, LDIFWriterEntryTranslator

@ThreadSafety(level=COMPLETELY_THREADSAFE)
public final class ExcludeAttributeTransformation
extends java.lang.Object
implements EntryTransformation, LDIFChangeRecordTransformation

This class provides an implementation of an entry and LDIF change record transformation that will remove a specified set of attributes from entries or change records. Note that this transformation will not alter entry DNs, so if an attribute to exclude is included in an entry's DN, that value will still be visible in the DN even if it is removed from the set of attributes in the entry.

ExcludeAttributeTransformation

public ExcludeAttributeTransformation(@Nullable
                                      Schema schema,
                                      @NotNull
                                      java.lang.String... attributes)

Creates a new exclude attribute transformation that will strip the specified attributes out of entries and change records.

Parameters:

schema - The scheme to use to identify alternate names that may be used to reference the attributes to exclude from entries. It may be null to use a default standard schema.

attributes - The names of the attributes to strip from entries and change records. It must not be null or empty.

Creates a new exclude attribute transformation that will strip the specified attributes out of entries and change records.

Parameters:

schema - The scheme to use to identify alternate names that may be used to reference the attributes to exclude from entries. It may be null to use a default standard schema.

attributes - The names of the attributes to strip from entries and change records. It must not be null or empty.

Method Detail

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.
