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

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==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.
