java.lang.Object javax.naming.directory.BasicAttributes

All Implemented Interfaces:

Attributes

Most common way to construct:

BasicAttributes attr = new BasicAttributes();

Based on 30 examples

public class BasicAttributes
extends 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.

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(String attrID,
                       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.

val - The value of the attribute to add. If null, a null value is added to the attribute.

BasicAttributes

public BasicAttributes(String attrID,
                       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.

clone

public Object clone()

Overrides:

clone in class Object

equals

public boolean equals(Object obj)

Determines whether this BasicAttributes is equal to another Attributes Two Attributes are equal if they are both instances of Attributes, treat the case of attribute IDs the same way, and contain the same attributes. Each Attribute in this BasicAttributes is checked for equality using Object.equals(), which may have be overridden by implementations of Attribute). If a subclass overrides equals(), it should override hashCode() as well so that two Attributes instances that are equal have the same hash code.

Overrides:

equals in class Object

Parameters:

obj - the possibly null object to compare against.

Returns:

true If obj is equal to this BasicAttributes.

get

public Attribute get(String attrID)

Parameters:

attrID

getAll

public NamingEnumeration getAll()

getIDs

public NamingEnumeration getIDs()

hashCode

public int hashCode()

Calculates the hash code of this BasicAttributes.

The hash code is computed by adding the hash code of the attributes of this object. If this BasicAttributes ignores case of its attribute IDs, one is added to the hash code. If a subclass overrides hashCode(), it should override equals() as well so that two Attributes instances that are equal have the same hash code.

Overrides:

hashCode in class Object

Returns:

an int representing the hash code of this BasicAttributes instance.

isCaseIgnored

public boolean isCaseIgnored()

put

public Attribute put(Attribute attr)

Parameters:

attr

put

public Attribute put(String attrID,
                     Object val)

Parameters:

attrID

val

remove

public Attribute remove(String attrID)

Parameters:

attrID

size

public int size()

toString

public 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.

Overrides:

toString in class Object

Returns:

A non-null string listing the contents of this attribute set.
