Constructor Detail

CaseInsensitiveHashMap

public CaseInsensitiveHashMap()

Constructs an empty CaseInsensitiveHashMap with the default initial capacity (16) and the default load factor (0.75).

CaseInsensitiveHashMap

public CaseInsensitiveHashMap(int initialCapacity)

Constructs an empty CaseInsensitiveHashMap with the specified initial capacity and the default load factor (0.75).

Parameters:

initialCapacity - the initial capacity.

Throws:

IllegalArgumentException - if the initial capacity is negative.

CaseInsensitiveHashMap

public CaseInsensitiveHashMap(int initialCapacity,
                              float loadFactor)

Constructs an empty CaseInsensitiveHashMap with the specified initial capacity and load factor.

Parameters:

initialCapacity - The initial capacity.

loadFactor - The load factor.

Throws:

IllegalArgumentException - if the initial capacity is negative or the load factor is nonpositive.

CaseInsensitiveHashMap

public CaseInsensitiveHashMap(Map<? extends String,? extends V> m)

Constructs a new CaseInsensitiveHashMap with the same mappings as the specified Map. The CaseInsensitiveHashMap is created with default load factor (0.75) and an initial capacity sufficient to hold the mappings in the specified Map. This relies on the HashMap.putAll() implementation calling put().

Parameters:

m - the map whose mappings are to be placed in this map.

Throws:

NullPointerException - if the specified map is null.

put

public V put(String key,
             V value)

Override HashMap

Specified by:

put in interface Map<String,V>

Overrides:

Parameters:

key - key whose associated value is to be returned.

Returns:

previous value associated with specified key
