Constructor Detail

LongLinkedHashMap

public LongLinkedHashMap(int initialCapacity,
                         float loadFactor)

Constructs an empty insertion-ordered LinkedHashMap instance with the specified initial capacity and load factor.

Parameters:

initialCapacity - the initial capacity

loadFactor - the load factor

Throws:

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

LongLinkedHashMap

public LongLinkedHashMap(int initialCapacity)

Constructs an empty insertion-ordered LinkedHashMap instance with the specified initial capacity and a default load factor (0.75).

Parameters:

initialCapacity - the initial capacity

Throws:

java.lang.IllegalArgumentException - if the initial capacity is negative

LongLinkedHashMap

public LongLinkedHashMap()

Constructs an empty insertion-ordered LinkedHashMap instance with the default initial capacity (16) and load factor (0.75).

Method Detail

init

protected void init()

Called by superclass constructors and pseudoconstructors (clone, readObject) before any entries are inserted into the map. Initializes the chain.

Overrides:

init in class LongHashMap<V>

keys

public long[] keys()

Returns true if this map maps one or more keys to the specified value.

Overrides:

keys in class LongHashMap<V>

Parameters:

value - value whose presence in this map is to be tested

Returns:

true if this map maps one or more keys to the specified value

keysReverse

public long[] keysReverse()

valuesIterator

public java.util.Iterator<V> valuesIterator()

Overrides:

valuesIterator in class LongHashMap<V>

valuesReverseIterator

public java.util.Iterator<V> valuesReverseIterator()

clear

public void clear()

Removes all of the mappings from this map. The map will be empty after this call returns.

Overrides:

clear in class LongHashMap<V>
