Class ObjectLongHashMap

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap

com.jalios.util.ObjectLongHashMap

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.Map

public class ObjectLongHashMap
extends java.util.HashMap

This class is a map which binds key Object to long value.

This class is NOT thread safe, synchronize read and write operation when used in multi-threaded context if you really need features provided by this collection.
In multithreaded context, it may be wiser to use alternative thread safe and type safe collection such as ConcurrentHashMap<YourType, Long>.

Method Detail

remove

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

Specified by:

remove in interface java.util.Map

Overrides:

remove in class java.util.HashMap

clear

public void clear()

Specified by:

clear in interface java.util.Map

Overrides:

clear in class java.util.HashMap

put

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

Associates 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.

value - value to be associated with the specified key.

getLong

public long getLong(java.lang.Object key,
                    long defaultValue)

Return the long value associated with given object, or the given default value if object is not in this map.

Parameters:

key - the object from which to get associated value

defaultValue - the default value to use if object not present.

Returns:

long value associated to object

getMax

public long getMax()

Return maximum value stored in this map.

Returns:

maximum long value
