Class BasicAttributes

java.lang.Object
  |
  +--javax.naming.directory.BasicAttributes

public class BasicAttributes
extends java.lang.Object
implements Attributes

This class provides a basic implementation of the Attributes interface.

BasicAttributes is either case-sensitive or case-insensitive (case-ignore). This property is determined at the time the BasicAttributes constructor is called. In a case-insensitive BasicAttributes, the case of its attribute identifiers is ignored when searching for an attribute, or adding attributes. In a case-sensitive BasicAttributes, the case is significant.

When the BasicAttributes class needs to create an Attribute, it uses BasicAttribute. There is no other dependency on BasicAttribute.

Note that updates to BasicAttributes (such as adding or removing an attribute) does not affect the corresponding representation in the directory. Updates to the directory can only be effected using operations in the DirContext interface.

A BasicAttributes instance is not synchronized against concurrent multithreaded access. Multiple threads trying to access and modify a single BasicAttributes instance should lock the object.

Constructor Detail

BasicAttributes

public BasicAttributes()
Constructs a new instance of Attributes. The character case of attribute identifiers is significant when subsequently retrieving or adding attributes.

BasicAttributes

public BasicAttributes(boolean ignoreCase)
Constructs a new instance of Attributes. If ignoreCase is true, the character case of attribute identifiers is ignored; otherwise the case is significant.
Parameters:
ignoreCase - true means this attribute set will ignore the case of its attribute identifiers when retrieving or adding attributes; false means case is respected.

BasicAttributes

public BasicAttributes(java.lang.String attrID,
                       java.lang.Object val)
Constructs a new instance of Attributes with one attribute. The attribute specified by attrID and val are added to the newly created attribute. The character case of attribute identifiers is significant when subsequently retrieving or adding attributes.
Parameters:
attrID - non-null The id of the attribute to add. If this attribute set ignores the character case of its attribute ids, the case of attrID is ignored.
val - The value of the attribute to add. If null, a null value is added to the attribute.

BasicAttributes

public BasicAttributes(java.lang.String attrID,
                       java.lang.Object val,
                       boolean ignoreCase)
Constructs a new instance of Attributes with one attribute. The attribute specified by attrID and val are added to the newly created attribute. If ignoreCase is true, the character case of attribute identifiers is ignored; otherwise the case is significant.
Parameters:
attrID - non-null The id of the attribute to add. If this attribute set ignores the character case of its attribute ids, the case of attrID is ignored.
val - The value of the attribute to add. If null, a null value is added to the attribute.
ignoreCase - true means this attribute set will ignore the case of its attribute identifiers when retrieving or adding attributes; false means case is respected.
Method Detail

clone

public java.lang.Object clone()
Makes a copy of this attribute set. The new set contains the same attributes as the original set: the attributes are not themselves cloned. Changes to the copy will not affect the original and vice versa.
Specified by:
clone in interface Attributes
Returns:
A non-null copy of this attribute set.
Overrides:
clone in class java.lang.Object

isCaseIgnored

public boolean isCaseIgnored()
Determines whether this attribute set ignores the case of attribute identifiers when retrieving or adding attributes.
Specified by:
isCaseIgnored in interface Attributes
Returns:
true if case is ignored; false otherwise.

size

public int size()
Retrieves the number of attributes in this attribute set.
Specified by:
size in interface Attributes
Returns:
The nonnegative number of attributes in this attribute set.

get

public Attribute get(java.lang.String attrID)
Retrieves the attribute with the given attribute id from this set. Returns null if not found.
Specified by:
get in interface Attributes
Parameters:
attrID - The non-null id of the attribute to retrieve. If this attribute set ignores the character case of its attribute ids, the case of attrID is ignored.
Returns:
The attribute identified by attrID; null if not found.
See Also:
put(java.lang.String, java.lang.Object), remove(java.lang.String)

getAll

public NamingEnumeration getAll()
Retrieves an enumeration of the attributes in this attribute set. The effects of updates to this attribute set on this enumeration are undefined.
Specified by:
getAll in interface Attributes
Returns:
A non-null enumeration of the attributes in this attribute set. Each element of the enumeration is of class Attribute. If attribute set has zero attributes, an empty enumeration is returned.

getIDs

public NamingEnumeration getIDs()
Retrieves an enumeration of the ids of the attributes in this attribute set. The effects of updates to this attribute set on this enumeration are undefined.
Specified by:
getIDs in interface Attributes
Returns:
A non-null enumeration of the attributes' ids in this attribute set. Each element of the enumeration is of class String. If attribute set has zero attributes, an empty enumeration is returned.

put

public Attribute put(java.lang.String attrID,
                     java.lang.Object val)
Adds a new attribute to this attribute set.
Specified by:
put in interface Attributes
Parameters:
attrID - non-null The id of the attribute to add. If this attribute set ignores the character case of its attribute ids, the case of attrID is ignored.
val - The possibly null value of the attribute to add. If null, the attribute does not have any values.
Returns:
The Attribute with attrID that was previous in this attribute set; null if no such attribute existed.
See Also:
remove(java.lang.String)

put

public Attribute put(Attribute attr)
Adds a new attribute to this attribute set.
Specified by:
put in interface Attributes
Parameters:
attr - The non-null attribute to add. If this attribute set ignores the character case of its attribute ids, the case of attr's identifier is ignored.
Returns:
The Attribute with the same ID as attr that was previous in this attribute set; null if no such attribute existed.
See Also:
remove(java.lang.String)

remove

public Attribute remove(java.lang.String attrID)
Removes the attribute with the attribute id 'attrID' from this attribute set. If the attribute does not exist, ignore.
Specified by:
remove in interface Attributes
Parameters:
attrID - The non-null id of the attribute to remove. If this attribute set ignores the character case of its attribute ids, the case of attrID is ignored.
Returns:
The Attribute with the same ID as attr that was previous in this attribute set; null if no such attribute existed.

toString

public java.lang.String toString()
Generates the string representation of this attribute set. The string consists of each attribute identifier and the contents of each attribute. The contents of this string is useful for debugging and is not meant to be interpreted programmatically.
Returns:
A non-null string listing the contents of this attribute set.
Overrides:
toString in class java.lang.Object
