Class IlpDefaultValueMap

java.lang.Object
  java.util.AbstractMap<K,V>
      java.util.HashMap
          ilog.cpl.util.IlpDefaultValueMap

All Implemented Interfaces:

IlpValueMap, Serializable, Cloneable, Map

public class IlpDefaultValueMap
extends HashMap
implements IlpValueMap

CPL mapping table implementation using hash map.

Note that this implementation does not ensure consistency between the key and value type declaration and the content of the map itself.

Compatibility Note: In JViews 8.0, this class was moved from ilog.cpl.service to ilog.cpl.util.

Since:

JViews 8.0

                          Class valueClass)

Constructs a new, empty mapping.

Parameters:

keyClass - The Java type of the keys in the mapping.

valueClass - The Java type of the values returned by the mapping.

IlpDefaultValueMap

public IlpDefaultValueMap(Class keyClass,
                          Class valueClass,
                          Map map)

Constructs a new mapping from the given map.

Parameters:

keyClass - The Java type of the keys in the mapping.

valueClass - The Java type of the values returned by the mapping.

map - The map to be copied into this one.

Method Detail

clone

public Object clone()

Returns a shallow copy of this instance: the keys and values themselves are not cloned.

Overrides:

clone in class HashMap

Returns:

A shallow copy of this mapping.

getKeyClass

public Class getKeyClass()

Returns the Java type of the keys used in this mapping.

Specified by:

getKeyClass in interface IlpValueMap

Returns:

The Java type of the keys.

getValueClass

public Class getValueClass()

Returns the type of the values returned by this mapping. As this type may be any kind of Object, the result of this method is an Object.

Specified by:

getValueClass in interface IlpValueMap

Returns:

The type of the returned values.

getValue

public Object getValue(Object key)

Returns the value of the mapping for a specific key.

Specified by:

getValue in interface IlpValueMap

Parameters:

key - The key for which to get the value.

Returns:

Value associated with the key.

addValue

public boolean addValue(Object key,
                        Object value)

Adds a new key-value set.

Specified by:

addValue in interface IlpValueMap

Parameters:

key - The key for the mapping. The key may be null.

value - The value to be added. The value may be null.
