java.util.HashMap
   org.apache.catalina.util.ParameterMap

ParameterMap
final public class ParameterMap extends HashMap (Code)
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.

public  ParameterMap(int initialCapacity, float loadFactor)
     Construct a new, empty map with the specified initial capacity and load factor.
public  ParameterMap(Map map)
     Construct a new map with the same mappings as the given map.

Method Summary
public  voidclear()

Constructor Detail
ParameterMap
public ParameterMap()(Code)
Construct a new, empty map with the default initial capacity and load factor.



ParameterMap
public ParameterMap(int initialCapacity)(Code)
Construct a new, empty map with the specified initial capacity and default load factor.
Parameters:
  initialCapacity - The initial capacity of this map



ParameterMap
public ParameterMap(int initialCapacity, float loadFactor)(Code)
Construct a new, empty map with the specified initial capacity and load factor.
Parameters:
  initialCapacity - The initial capacity of this map
Parameters:
  loadFactor - The load factor of this map



ParameterMap
public ParameterMap(Map map)(Code)
Construct a new map with the same mappings as the given map.
Parameters:
  map - Map whose contents are dupliated in the new map




Method Detail
clear
public void clear()(Code)
Remove all mappings from this map.
exception:
  IllegalStateException - if this map is currently locked



isLocked
public boolean isLocked()(Code)
Return the locked state of this parameter map.



put
public Object put(Object key, Object value)(Code)
Associate the specified value with the specified key in this map. If the map previously contained a mapping for this key, the old value is replaced.
Parameters:
  key - Key with which the specified value is to be associated
Parameters:
  value - Value to be associated with the specified key The previous value associated with the specified key, ornull if there was no mapping for key
exception:
  IllegalStateException - if this map is currently locked



putAll
public void putAll(Map map)(Code)
Copy all of the mappings from the specified map to this one. These mappings replace any mappings that this map had for any of the keys currently in the specified Map.
Parameters:
  map - Mappings to be stored into this map
exception:
  IllegalStateException - if this map is currently locked



remove
public Object remove(Object key)(Code)
Remove the mapping for this key from the map if present.
Parameters:
  key - Key whose mapping is to be removed from the map The previous value associated with the specified key, ornull if there was no mapping for that key
exception:
  IllegalStateException - if this map is currently locked



setLocked
public void setLocked(boolean locked)(Code)
Set the locked state of this parameter map.
Parameters:
  locked - The new locked state
