Class DelegatedPropertyMap

java.lang.Object
  de.unidu.is.util.PropertyMap
      de.unidu.is.util.DelegatedPropertyMap

All Implemented Interfaces:

java.util.Map

Direct Known Subclasses:

HashPropertyMap, StreamPropertyMap

public class DelegatedPropertyMap

extends PropertyMap

This class delegates all calls to another map. This map implementation can be initialised by another map. The keys of this initialisation map are stored separately, so that these entries can be distinguished from the "ordinary" entries lateron.

Field Detail

map

protected java.util.Map map

Map implementation to which all calls are delegated.

initKeys

protected java.util.Set initKeys

Set containing initial keys.

Constructor Detail

DelegatedPropertyMap

public DelegatedPropertyMap(java.util.Map map)

Creates a new instance.

Parameters:

map - to which calls are delegated

DelegatedPropertyMap

public DelegatedPropertyMap(java.util.Map map,
                            boolean multipleValues)

Creates a new instance.

Parameters:

map - to which calls are delegated

multipleValues - values if true, multiple values can be hold for a key

Method Detail

init

public void init(java.util.Map init)

Inits the map by setting the initial keys and values. These values are not original entries and can be distinguished lateron.

Parameters:

init - map for initialisation (may be null)

changed

protected void changed()

Calls whenever the map is changed.

Subclasses can override this method.

clear

public void clear()

Removes all entries.

containsKey

public boolean containsKey(java.lang.Object key)

containsValue

public boolean containsValue(java.lang.Object value)

entrySet

public java.util.Set entrySet()

equals

public boolean equals(java.lang.Object obj)

get

public java.lang.Object get(java.lang.Object key)

hashCode

public int hashCode()

isEmpty

public boolean isEmpty()

keySet

public java.util.Set keySet()

put

public java.lang.Object put(java.lang.Object key,
                            java.lang.Object value)

putNoChange

public java.lang.Object putNoChange(java.lang.Object key,
                                    java.lang.Object value)

Puts the (key,vaue) pair into the map without calling the changed() method.

Parameters:

key - key

value - value for the key

Returns:

previous value

putInitial

public java.lang.Object putInitial(java.lang.Object key,
                                   java.lang.Object value)

Sets an initial value which can be distinguished from "ordinary" entries lateron.

Parameters:

key - entry key

value - entry value

Returns:

previous value associated with specified key, or null if no value is available

putAll

public void putAll(java.util.Map t)

remove
