public interface Attributes

An interface that represents a collectoin of Attributes. Unlike the Attribute interface, this interface is not read-only. Methods are provided to update the underlying collection by adding, removing, or updating the attributes it holds. There is no factory method on this interface; instead, services that take Attributes parameters have methods for generating instances of Attributes appropriate to the purpose at hand.

Method Summary

void	addAttribute(String name, String[] values, boolean replace) Add the specified attribute to the attributes collection.
void	addAttribute(String name, String value, boolean replace) Add the specified attribute to the attributes collection.
void	clear() Removes all attributes from the collection.
Attribute	getAttribute(String name) Get the Attribute object for the named attribute, if present.
int	getAttributeCount() Get a count of the number of Attributes (not attribute values) in this Attributes object.
Set<String>	getAttributeNames() Get the attribute names, as a Set.
String	getAttributeValue(String name) Get the value of the specified attribute, if present.
Set<String>	getAttributeValues(String name) Get the Set of values for the specified attribute, if present.
String[]	getAttributeValuesAsArray(String name) Get the set of values for the specified attribute as a String array.

Method Detail

getAttributeCount

int getAttributeCount()

Get a count of the number of Attributes (not attribute values) in this Attributes object.

Returns:

The attribute count.

getAttributeNames

Set<String> getAttributeNames()

Get the attribute names, as a Set. This set is read-only; updating it will not change the underlying attributes collection.

Returns:

The attribute names Set.

getAttribute

Attribute getAttribute(String name)

Get the Attribute object for the named attribute, if present.

Parameters:

name - The name of the Attribute to get.

Returns:

The Attribute, or null if an attribute by that name is not present.

getAttributeValue

String getAttributeValue(String name)

Get the value of the specified attribute, if present. Note that, for multi-valued attributes, The value returned is whichever value is returned first by the underlying Set implementation; there are no ordering guarantees. As such, this method is primarily useful as a shorthand method for attributes known (or expected) by the caller to be single-valued. Note also that it is not possible, using this method, to distinguish between a missing attribute and an attribute that is present but has no values. In both cases, null is returned.

Parameters:

name - The name of the attribute whose value is wanted.

Returns:

The attribute value, or null if the attribute is missing or has no values.

getAttributeValues

Set<String> getAttributeValues(String name)

Get the Set of values for the specified attribute, if present.

Parameters:

name - The name of the attribute whose values are wanted.

Returns:

The Set of values, or null if the attribute is not present in the collection. If the attribute is present but has no values, an empty Set is returned.

getAttributeValuesAsArray

String[] getAttributeValuesAsArray(String name)

Get the set of values for the specified attribute as a String array.

Parameters:

name - The name of the attribute whose values are wanted.

Returns:

The array of values, or null if the attribute is not present in the collection. If the attribute is present but has no values, a zero-length array is returned.

addAttribute

void addAttribute(String name,
                  String value,
                  boolean replace)

Add the specified attribute to the attributes collection. Remove any existing values if the replace parameter is true, otherwise add the new value to the existing values. Duplicate values are silently dropped.

Parameters:

name - The name of the attribute to add.

value - The single attribute value to add.

replace - If true, replace the existing attribute and any existing values. If false, add the new value to those that are already present.

addAttribute

void addAttribute(String name,
                  Set<String> values,
                  boolean replace)

Add the specified attribute to the attributes collection. Remove any existing values if the replace parameter is true, otherwise add the new values to the existing values. Duplicate values are silently dropped.

Parameters:

name - The name of the attribute to add.

value - The Set of values to add.

replace - If true, replace the existing attribute and any existing values. If false, add the new values to those that are already present.

addAttribute

void addAttribute(String name,
                  String[] values,
                  boolean replace)

Add the specified attribute to the attributes collection. Remove any existing values if the replace parameter is true, otherwise add the new values to the existing values. Duplicate values are silently dropped.

Parameters:

name - The name of the attribute to add.

value - The array of values to add.

replace - If true, replace the existing attribute and any existing values. If false, add the new values to those that are already present.

removeAttribute

void removeAttribute(String name)

Remove the specified attribute from the collection.

Parameters:

name - The name of the attribute to remove.

removeAttributeValue

void removeAttributeValue(String name,
                          String value)

Remove the specified value from the named attribute.

Parameters:

name - The name of the attribute from which to remove a value.

value - The value to remove. A value will be removed only if it exactly matches this parameter.

removeAttributeValues

void removeAttributeValues(String name,
                           Set<String> values)

Remove the specified values from the named attribute.

Parameters:

name - The name of the attribute from which to remove the values.

value - The Set of values to remove. Only values that exactly match values in this Set will be removed.

Parameters:

name - The name of the attribute whose values should be removed.

clear

void clear()
