| Constructor and Description |
|---|
SimpleBindings()
Default constructor uses a
HashMap. |
SimpleBindings(Map<String,Object> m)
Constructor uses an existing
Map to store the values. |
| Modifier and Type | Method and Description |
|---|---|
void |
clear()
Removes all of the mappings from this map (optional operation).
|
boolean |
containsKey(Object key)
Returns true if this map contains a mapping for the specified
key.
|
boolean |
containsValue(Object value)
Returns true if this map maps one or more keys to the
specified value.
|
Set<Map.Entry<String,Object>> |
entrySet()
Returns a
Set view of the mappings contained in this map. |
Object |
get(Object key)
Returns the value to which this map maps the specified key.
|
boolean |
isEmpty()
Returns true if this map contains no key-value mappings.
|
Set<String> |
keySet()
Returns a
Set view of the keys contained in this map. |
Object |
put(String name,
Object value)
Sets the specified key/value in the underlying
map field. |
void |
putAll(Map<? extends String,? extends Object> toMerge)
putAll is implemented using Map.putAll. |
Object |
remove(Object key)
Removes the mapping for this key from this map if it is present
(optional operation).
|
int |
size()
Returns the number of key-value mappings in this map.
|
Collection<Object> |
values()
Returns a
Collection view of the values contained in this map. |

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.public Object get(Object key)
More formally, if this map contains a mapping from a key k to a value v such that (key==null ? k==null : key.equals(k)), then this method returns v; otherwise it returns null. (There can be at most one such mapping.)

public Set<String> keySet()
Set view of the keys contained in this map.

(key==null ? k==null : key.equals(k)), that mapping
is removed. (The map can contain at most one such mapping.)
Returns the value to which the map previously associated the key, or null if the map contained no mapping for this key. (A null return can also indicate that the map previously associated null with the specified key if the implementation supports null values.) The map will not contain a mapping for the specified key once the call returns.

public Collection<Object> values()
Collection view of the values contained in this map.
The collection is backed by the map, so changes to the map are
reflected in the collection, and vice-versa. If the map is
modified while an iteration over the collection is in progress
(except through the iterator's own remove operation),
the results of the iteration are undefined. The collection
supports element removal, which removes the corresponding
mapping from the map, via the Iterator.remove,
Collection.remove, removeAll,
retainAll and clear operations. It does not
support the add or addAll operations. Submit a bug or feature
