Class BasicAttributes

- javax.naming.directory.BasicAttributes

,Attributes
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.

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(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.
Method Detail
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 classObject
- Returns:
- A non-null string listing the contents of this attribute set.
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 classObject
- Parameters:
-
obj
- the possibly null object to compare against. - Returns:
- true If obj is equal to this BasicAttributes.
- See Also:
hashCode()
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 classObject
- Returns:
- an int representing the hash code of this BasicAttributes instance.
