Inherited Methods

From class java.util.AbstractMap

void	clear() Removes all of the mappings from this map (optional operation). This implementation calls `entrySet().clear()`.
Object	clone() Returns a shallow copy of this `AbstractMap` instance: the keys and values themselves are not cloned.
boolean	containsKey(Object key) Returns `true` if this map contains a mapping for the specified key. This implementation iterates over `entrySet()` searching for an entry with the specified key.
boolean	containsValue(Object value) Returns `true` if this map maps one or more keys to the specified value. This implementation iterates over `entrySet()` searching for an entry with the specified value.
abstract Set<Entry<K, V>>	entrySet() Returns a `Set` view of the mappings contained in this map.
boolean	equals(Object o) Compares the specified object with this map for equality.
V	get(Object key) Returns the value to which the specified key is mapped, or `null` if this map contains no mapping for the key. This implementation iterates over `entrySet()` searching for an entry with the specified key.
int	hashCode() Returns the hash code value for this map.
boolean	isEmpty() Returns `true` if this map contains no key-value mappings. This implementation returns `size() == 0`.
Set<K>	keySet() Returns a `Set` view of the keys contained in this map. This implementation returns a set that subclasses `AbstractSet`.
V	put(K key, V value) Associates the specified value with the specified key in this map (optional operation). This implementation always throws an `UnsupportedOperationException`.
void	putAll(Map<? extends K, ? extends V> m) Copies all of the mappings from the specified map to this map (optional operation). This implementation iterates over the specified map's `entrySet()` collection, and calls this map's `put` operation once for each entry returned by the iteration.
V	remove(Object key) Removes the mapping for a key from this map if it is present (optional operation). This implementation iterates over `entrySet()` searching for an entry with the specified key.
int	size() Returns the number of key-value mappings in this map. This implementation returns `entrySet().size()`.
String	toString() Returns a string representation of this map.
Collection<V>	values() Returns a `Collection` view of the values contained in this map. This implementation returns a collection that subclasses `AbstractCollection`.

From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Public Constructors

public AttributeMap (AttributeValues values)

Public Methods

public Set<Entry<TextAttribute, Object>> entrySet ()

Returns a Set view of the mappings contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation, or through the setValue operation on a map entry returned by the iterator) the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.

Returns

a set view of the mappings contained in this map

public AttributeValues getValues ()

public Object put (TextAttribute key, Object value)

Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value. (A map m is said to contain a mapping for a key k if and only if m.containsKey(k) would return true.)

This implementation always throws an UnsupportedOperationException.

Parameters

key	key with which the specified value is to be associated
value	value to be associated with the specified key

Returns

the previous value associated with key, or null if there was no mapping for key. (A null return can also indicate that the map previously associated null with key, if the implementation supports null values.)

public String toString ()

Returns a string representation of this map. The string representation consists of a list of key-value mappings in the order returned by the map's entrySet view's iterator, enclosed in braces ("{}"). Adjacent mappings are separated by the characters ", " (comma and space). Each key-value mapping is rendered as the key followed by an equals sign ("=") followed by the associated value. Keys and values are converted to strings as by valueOf(Object).

Returns

a string representation of this map
