Method Detail

toBasicAttribute

public static Attribute toBasicAttribute(org.apache.directory.shared.ldap.entry.EntryAttribute entryAttribute)

Convert a ServerAttribute into a BasicAttribute. The DN is lost during this conversion, as the Attributes object does not store this element.

Returns:

An instance of a AttributesImpl() object

toBasicAttributes

public static Attributes toBasicAttributes(org.apache.directory.shared.ldap.entry.ServerEntry entry)

Convert a ServerEntry into a BasicAttributes. The DN is lost during this conversion, as the Attributes object does not store this element.

Returns:

An instance of a AttributesImpl() object

toServerAttribute

public static org.apache.directory.shared.ldap.entry.EntryAttribute toServerAttribute(Attribute attribute,
                                                                      org.apache.directory.shared.ldap.schema.AttributeType attributeType)

Convert a BasicAttribute or a AttributeImpl to a ServerAtribute

Parameters:

attribute - the BasicAttributes or AttributesImpl instance to convert

attributeType -

Returns:

An instance of a ServerEntry object

Throws:

InvalidAttributeIdentifierException - If we had an incorrect attribute

toServerEntry

public static org.apache.directory.shared.ldap.entry.ServerEntry toServerEntry(Attributes attributes,
                                                               org.apache.directory.shared.ldap.name.DN dn,

                                                                        throws org.apache.directory.shared.ldap.exception.LdapInvalidAttributeTypeException

Convert a BasicAttributes or a AttributesImpl to a ServerEntry

Parameters:

attributes - the BasicAttributes or AttributesImpl instance to convert

registries - The registries, needed ro build a ServerEntry

dn - The DN which is needed by the ServerEntry

Returns:

An instance of a ServerEntry object

Throws:

org.apache.directory.shared.ldap.exception.LdapInvalidAttributeTypeException - If we get an invalid attribute

getTargetEntry

public static org.apache.directory.shared.ldap.entry.ServerEntry getTargetEntry(org.apache.directory.shared.ldap.entry.Modification mod,
                                                                org.apache.directory.shared.ldap.entry.ServerEntry entry,

Gets the target entry as it would look after a modification operation was performed on it.

Parameters:

mod - the modification

entry - the source entry that is modified

Returns:

the resultant entry after the modification has taken place

Throws:

org.apache.directory.shared.ldap.exception.LdapException - if there are problems accessing attributes

getUnion

public static org.apache.directory.shared.ldap.entry.EntryAttribute getUnion(org.apache.directory.shared.ldap.entry.EntryAttribute attr0,
                                                             org.apache.directory.shared.ldap.entry.EntryAttribute attr1)

Creates a new attribute which contains the values representing the union of two attributes. If one attribute is null then the resultant attribute returned is a copy of the non-null attribute. If both are null then we cannot determine the attribute ID and an IllegalArgumentException is raised.

Parameters:

attr0 - the first attribute

attr1 - the second attribute

Returns:

a new attribute with the union of values from both attribute arguments

Throws:

org.apache.directory.shared.ldap.exception.LdapException - if there are problems accessing attribute values
