SimpleBindings

• java.lang.Object

Fields Summary
private Map	map The Map field stores the attributes.

Constructors Summary
public SimpleBindings(Map m) Constructor uses an existing Map to store the values. param m The Map backing this SimpleBindings. throws NullPointerException if m is null if (m == null) { throw new NullPointerException(); } this.map = m;
public SimpleBindings() Default constructor uses a HashMap. this(new HashMap<String,Object>());

Methods Summary
private void	checkKey(java.lang.Object key) if (key == null) { throw new NullPointerException("key can not be null"); } if (!(key instanceof String)) { throw new ClassCastException("key should be a String"); } if (key.equals("")) { throw new IllegalArgumentException("key can not be empty"); }
public void	clear() {@inheritDoc} map.clear();
public boolean	containsKey(java.lang.Object key) Returns true if this map contains a mapping for the specified key. More formally, returns true if and only if this map contains a mapping for a key k such that (key==null ? k==null : key.equals(k)). (There can be at most one such mapping.) param key key whose presence in this map is to be tested. return true if this map contains a mapping for the specified key. throws NullPointerException if key is null throws ClassCastException if key is not String throws IllegalArgumentException if key is empty String checkKey(key); return map.containsKey(key);
public boolean	containsValue(java.lang.Object value) {@inheritDoc} return map.containsValue(value);
public java.util.Set	entrySet() {@inheritDoc} return map.entrySet();
public java.lang.Object	get(java.lang.Object key) Returns the value to which this map maps the specified key. Returns null if the map contains no mapping for this key. A return value of null does not necessarily indicate that the map contains no mapping for the key; it's also possible that the map explicitly maps the key to null. The containsKey operation may be used to distinguish these two cases. 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.) param key key whose associated value is to be returned. return the value to which this map maps the specified key, or null if the map contains no mapping for this key. throws NullPointerException if key is null throws ClassCastException if key is not String throws IllegalArgumentException if key is empty String checkKey(key); return map.get(key);
public boolean	isEmpty() {@inheritDoc} return map.isEmpty();
public java.util.Set	keySet() {@inheritDoc} return map.keySet();
public java.lang.Object	put(java.lang.String name, java.lang.Object value) Sets the specified key/value in the underlying map field. param name Name of value param value Value to set. return Previous value for the specified key. Returns null if key was previously unset. throws NullPointerException if the name is null. throws IllegalArgumentException if the name is empty. checkKey(name); return map.put(name,value);
public void	putAll(java.util.Map toMerge) putAll is implemented using Map.putAll. param toMerge The Map of values to add. throws NullPointerException if toMerge map is null or if some key in the map is null. throws IllegalArgumentException if some key in the map is an empty String. if (toMerge == null) { throw new NullPointerException("toMerge map is null"); } for (Map.Entry<? extends String, ? extends Object> entry : toMerge.entrySet()) { String key = entry.getKey(); checkKey(key); put(key, entry.getValue()); }
public java.lang.Object	remove(java.lang.Object key) Removes the mapping for this key from this map if it is present (optional operation). More formally, if this map contains a mapping from key k to value v such that (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. param key key whose mapping is to be removed from the map. return previous value associated with specified key, or null if there was no mapping for key. throws NullPointerException if key is null throws ClassCastException if key is not String throws IllegalArgumentException if key is empty String checkKey(key); return map.remove(key);
public int	size() {@inheritDoc} return map.size();
public java.util.Collection	values() {@inheritDoc} return map.values();
