SimpleBindings()
Default constructor uses a HashMap. |
|
SimpleBindings(Map<String,Object> m)
Constructor uses an existing Map to store the values. |
|
| Method Summary | |
|---|---|
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). |

public SimpleBindings(Map<String,Object> m)
javax.script.SimpleBindings
Map to store the values.
m - The Map backing this SimpleBindings.
NullPointerException - if m is nullpublic SimpleBindings()
HashMap.
| Method Detail |

public Object put(String name, Object value)
map field.
name - Name of valuevalue - Value to set.
NullPointerException - if the name is null.
IllegalArgumentException - if the name is empty.public void putAll(Map<? extends String,? extends Object> toMerge)
putAll is implemented using Map.putAll.
toMerge - The Map of values to add.
NullPointerException - if toMerge map is null or if some key in the map is null.
IllegalArgumentException - if some key in the map is an empty String.public void clear()
public boolean containsKey(Object key)
containsKey in interface Map<String,Object>containsKey in interface Bindingskey - key whose presence in this map is to be tested.
NullPointerException - if key is null
ClassCastException - if key is not String
IllegalArgumentException - if key is empty Stringpublic boolean containsValue(Object value)
containsValue in interface Map<String,Object>value - value whose presence in this map is to be tested
public Set<Map.Entry<String,Object>> entrySet()
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.)
key - key whose associated value is to be returned.
NullPointerException - if key is null
ClassCastException - if key is not String
IllegalArgumentException - if key is empty Stringpublic boolean isEmpty()
public Set<String> keySet()
Set view of the keys 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), 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 remove(Object key)
(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.
key - key whose mapping is to be removed from the map.
NullPointerException - if key is null
ClassCastException - if key is not String
IllegalArgumentException - if key is empty Stringpublic int size()
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.
