Parameters:

key - The "mutable" key, which has the same identity/hashcode as the inserted key, only during this call

keyTransformer - If the record is absent, the transformer will transform the "mutable" key into an immutable copy of the key. Note that the transformed key must have the same identity/hashcode as the original "mutable" key.

factory - It creates an object, if it is not present in the map already.

toString

public java.lang.String toString()

Description copied from class: AbstractRichIterable

Returns a string representation of this collection.

Adjacent elements are separated by the characters ", " (comma and space). Elements are converted to strings as by String.valueOf(Object).

This implementation creates an empty string buffer, appends a left square bracket, and iterates over the collection appending the string representation of each element in turn. After appending each element except the last, the string ", " is appended. Finally a right bracket is appended. A string is obtained from the string buffer, and returned.

withKeyValue

public ConcurrentHashMapUnsafe<K,V> withKeyValue(K key,
                                        V value)

Description copied from interface: com.gs.collections.api.map.MutableMapIterable

This method allows mutable, fixed size, and immutable maps the ability to add elements to their existing elements. In order to support fixed size maps, a new instance of a map would have to be returned including the keys and values of the original plus the additional key and value. In the case of mutable maps, the original map is modified and then returned. In order to use this method properly with mutable and fixed size maps the following approach must be taken:

 map = map.withKeyValue("new key", "new value");
 

In the case of FixedSizeMap, a new instance will be returned by withKeyValue, and any variables that previously referenced the original map will need to be redirected to reference the new instance. In the case of a FastMap or UnifiedMap, you will be replacing the reference to map with map, since FastMap and UnifiedMap will both return "this" after calling put on themselves.

Specified by:

public ConcurrentHashMapUnsafe<K,V> withAllKeyValues(java.lang.Iterable<? extends com.gs.collections.api.tuple.Pair<? extends K,? extends V>> keyValues)

Description copied from interface: com.gs.collections.api.map.MutableMapIterable

This method allows mutable, fixed size, and immutable maps the ability to add elements to their existing elements. In order to support fixed size maps, a new instance of a map would have to be returned including the keys and values of the original plus all of the additional keys and values. In the case of mutable maps, the original map is modified and then returned. In order to use this method properly with mutable and fixed size maps the following approach must be taken:

 map = map.withAllKeyValues(FastList.newListWith(PairImpl.of("new key", "new value")));
 

In the case of FixedSizeMap, a new instance will be returned by withAllKeyValues, and any variables that previously referenced the original map will need to be redirected to reference the new instance. In the case of a FastMap or UnifiedMap, you will be replacing the reference to map with map, since FastMap and UnifiedMap will both return "this" after calling put on themselves.

withoutKey

public ConcurrentHashMapUnsafe<K,V> withoutKey(K key)

Description copied from interface: com.gs.collections.api.map.MutableMapIterable

This method allows mutable, fixed size, and immutable maps the ability to remove elements from their existing elements. In order to support fixed size maps, a new instance of a map would have to be returned including the keys and values of the original minus the key and value to be removed. In the case of mutable maps, the original map is modified and then returned. In order to use this method properly with mutable and fixed size maps the following approach must be taken:

 map = map.withoutKey("key");
 

In the case of FixedSizeMap, a new instance will be returned by withoutKey, and any variables that previously referenced the original map will need to be redirected to reference the new instance. In the case of a FastMap or UnifiedMap, you will be replacing the reference to map with map, since FastMap and UnifiedMap will both return "this" after calling remove on themselves.

This method allows mutable, fixed size, and immutable maps the ability to remove elements from their existing elements. In order to support fixed size maps, a new instance of a map would have to be returned including the keys and values of the original minus all of the keys and values to be removed. In the case of mutable maps, the original map is modified and then returned. In order to use this method properly with mutable and fixed size maps the following approach must be taken:

 map = map.withoutAllKeys(FastList.newListWith("key1", "key2"));
 

In the case of FixedSizeMap, a new instance will be returned by withoutAllKeys, and any variables that previously referenced the original map will need to be redirected to reference the new instance. In the case of a FastMap or UnifiedMap, you will be replacing the reference to map with map, since FastMap and UnifiedMap will both return "this" after calling remove on themselves.

forEachWith

public <P> void forEachWith(com.gs.collections.api.block.procedure.Procedure2<? super V,? super P> procedure,
                   P parameter)

Description copied from interface: com.gs.collections.api.InternalIterable

The procedure2 is evaluated for each element in the iterable with the specified parameter provided as the second argument.

Example using a Java 8 lambda:

Example using an anonymous inner class:

 people.forEachWith(new Procedure2()
 {
     public void value(Person person, Person other)
     {
         if (person.isRelatedTo(other))
         {
