Method Details

put
Sets the specified key/value in the underlyingmap
field.- Specified by:
put
in interfaceBindings
- Specified by:
put
in interfaceMap<String,
Object> - Parameters:
name
- Name of valuevalue
- Value to set.- Returns:
- Previous value for the specified key. Returns null if key was previously unset.
- Throws:
NullPointerException
- if the name is null.IllegalArgumentException
- if the name is empty.
-
putAll
putAll
is implemented usingMap.putAll
.- Specified by:
putAll
in interfaceBindings
- Specified by:
putAll
in interfaceMap<String,
Object> - Parameters:
toMerge
- TheMap
of values to add.- Throws:
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.
-
clear
public void clear() -
containsKey
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.)- Specified by:
containsKey
in interfaceBindings
- Specified by:
containsKey
in interfaceMap<String,
Object> - Parameters:
key
- key whose presence in this map is to be tested.- Returns:
- true if this map contains a mapping for the specified key.
- Throws:
NullPointerException
- if key is nullClassCastException
- if key is not StringIllegalArgumentException
- if key is empty String
-
containsValue
- Specified by:
containsValue
in interfaceMap<String,
Object>
-
entrySet
-
get
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.)
- Specified by:
get
in interfaceBindings
- Specified by:
get
in interfaceMap<String,
Object> - Parameters:
key
- key whose associated value is to be returned.- Returns:
- 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 nullClassCastException
- if key is not StringIllegalArgumentException
- if key is empty String
-
isEmpty
public boolean isEmpty() -
keySet
-
remove
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.
- Specified by:
remove
in interfaceBindings
- Specified by:
remove
in interfaceMap<String,
Object> - Parameters:
key
- key whose mapping is to be removed from the map.- Returns:
- previous value associated with specified key, or null if there was no mapping for key.
- Throws:
NullPointerException
- if key is nullClassCastException
- if key is not StringIllegalArgumentException
- if key is empty String
