Method Detail |

Object put(String name, Object value)
name
- The name associated with the value.value
- The value associated with the name.
NullPointerException
- if the name is null.
IllegalArgumentException
- if the name is empty String.void putAll(Map<? extends String,? extends Object> toMerge)
Map
to this Bindings
.
toMerge
- The Map
to merge with this one.
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.boolean containsKey(Object key)
containsKey
in interface Map<String,Object>
key
- 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 StringObject 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 StringObject 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 String
