Constructor Detail

ImmutableAttributes

public ImmutableAttributes()

Constructs an empty immutable Attributes object.

ImmutableAttributes

public ImmutableAttributes(@NotNull
                           Map<String,Set<String>> attributesMap)

Constructs an immutable Attributes object from the given Map. An immutable copy of the incoming map is built, so the passed map does not need to be immutable itself.

Parameters:

attributesMap - The incoming attributes Map.

ImmutableAttributes

public ImmutableAttributes(@NotNull
                           Attributes attributes)

Constructs an immutable copy of the passed in attributes.

Parameters:

attributes - to clone.

Method Detail

getValues

public Set<String> getValues(String key)

Description copied from interface: Attributes

Get all the values associated with a given key. Duplicate values are not allowed, and this should be enforced case-insensitively to match the behaviour of LDAP servers. Will return null if the key does not exist.

Specified by:

getValues in interface Attributes

Parameters:

key - the key to retrieve the values for

Returns:

the values associated with the given key, or null if the key does not exist.

getValue

public String getValue(String key)

Description copied from interface: Attributes

Returns any value associated with the given key, returns null if there is no value.

Specified by:

getValue in interface Attributes

Parameters:

key - the key to retrieve the value for

Returns:

any value associated with the given key, or null if there is no value

getKeys

public Set<String> getKeys()

Description copied from interface: Attributes

Gets all the keys of the attributes. Warning: case-insensitive keys are currently no enforced, however this is the case for LDAP, so this may be implemented in the future.

Specified by:

getKeys in interface Attributes

Returns:

a set of all the keys.

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Attributes

Returns:

true if there are no attributes
