java.lang.Object java.util.AbstractMap java.util.HashMap org.apache.catalina.util.ParameterMap
Extended implementation of HashMap that includes a
locked
property. This class can be used to safely expose
Catalina internal parameter map objects to user classes without having
to clone them in order to avoid modifications. When first created, a
ParmaeterMap
instance is not locked.
Constructor Summary | |
ParameterMap()
Construct a new, empty map with the default initial capacity and load factor. |
|
ParameterMap(int initialCapacity)
Construct a new, empty map with the specified initial capacity and default load factor. |
|
ParameterMap(int initialCapacity,
float loadFactor)
Construct a new, empty map with the specified initial capacity and load factor. |
|
ParameterMap(java.util.Map map)
Construct a new map with the same mappings as the given map. |
Method Summary | |
void |
clear()
Remove all mappings from this map. |
boolean |
isLocked()
Return the locked state of this parameter map. |
java.lang.Object |
put(java.lang.Object key,
java.lang.Object value)
Associate the specified value with the specified key in this map. |
void |
putAll(java.util.Map map)
Copy all of the mappings from the specified map to this one. |
java.lang.Object |
remove(java.lang.Object key)
Remove the mapping for this key from the map if present. |
void |
setLocked(boolean locked)
Set the locked state of this parameter map. |
