Adds a new value to this attribute.

  Adds a new value to this attribute.

By default, Object.equals() is used when comparing attrVal with this attribute's values except when attrVal is an array. For an array, each element of the array is checked using Object.equals(). A subclass may use schema information to determine equality.

  Determines whether a value is in this attribute.

  Determines whether a value is in this attribute.

By default, Object.equals() is used when comparing attrVal with this attribute's values except when attrVal is an array. For an array, each element of the array is checked using Object.equals(). A subclass may use schema information to determine equality.

  Determines whether obj is equal to this attribute.

  Determines whether obj is equal to this attribute. Two attributes are equal if their attribute-ids, syntaxes and values are equal. If the attribute values are unordered, the order that the values were added are irrelevant. If the attribute values are ordered, then the order the values must match. If obj is null or not an Attribute, false is returned.

By default Object.equals() is used when comparing the attribute id and its values except when a value is an array. For an array, each element of the array is checked using Object.equals(). A subclass may override this to make use of schema syntax information and matching rules, which define what it means for two attributes to be equal. How and whether a subclass makes use of the schema information is determined by the subclass. If a subclass overrides equals(), it should also override hashCode() such that two attributes that are equal have the same hash code.
Returns: true if obj is equal to this attribute; false otherwise.
Parameters:
- obj - The possibly null object to check.

  Retrieves one of this attribute's values.

  Retrieves one of this attribute's values.

By default, the value returned is one of those passed to the constructor and/or manipulated using the add/replace/remove methods. A subclass may override this to retrieve the value dynamically from the directory.

  Retrieves an enumeration of this attribute's values.

  Retrieves an enumeration of this attribute's values.

By default, the values returned are those passed to the constructor and/or manipulated using the add/replace/remove methods. A subclass may override this to retrieve the values dynamically from the directory.

  Retrieves this attribute's schema definition.

  Retrieves this attribute's schema definition.

This method by default throws OperationNotSupportedException. A subclass should override this method if it supports schema.

  Retrieves the syntax definition associated with this attribute.

  Retrieves the syntax definition associated with this attribute.

This method by default throws OperationNotSupportedException. A subclass should override this method if it supports schema.

  Calculates the hash code of this attribute.

  Calculates the hash code of this attribute.

The hash code is computed by adding the hash code of the attribute's id and that of all of its values except for values that are arrays. For an array, the hash code of each element of the array is summed. If a subclass overrides hashCode(), it should override equals() as well so that two attributes that are equal have the same hash code.
Returns: an int representing the hash code of this attribute.

  Removes a specified value from this attribute.

  Removes a specified value from this attribute.

By default, Object.equals() is used when comparing attrVal with this attribute's values except when attrVal is an array. For an array, each element of the array is checked using Object.equals(). A subclass may use schema information to determine equality.

  Generates the string representation of this attribute.

  Generates the string representation of this attribute.
The string consists of the attribute's id and its values.
This string is meant for debugging and not meant to be
interpreted programmatically.
Returns: The non-null string representation of this attribute.
