类 ObjectIntMap

java.lang.Object

com.vladium.util.ObjectIntMap

public final class ObjectIntMap
extends Object

MT-safety: an instance of this class is not safe for access from multiple concurrent threads [even if access is done by a single thread at a time]. The caller is expected to synchronize externally on an instance [the implementation does not do internal synchronization for the sake of efficiency]. java.util.ConcurrentModificationException is not supported either.

ObjectIntMap

public ObjectIntMap()

Equivalent to IntObjectMap(11, 0.75F).

ObjectIntMap

public ObjectIntMap(int initialCapacity)

Equivalent to IntObjectMap(capacity, 0.75F).

ObjectIntMap

public ObjectIntMap(int initialCapacity,
                    float loadFactor)

Constructs an IntObjectMap with specified initial capacity and load factor.

参数:

initialCapacity - initial number of hash buckets in the table [may not be negative, 0 is equivalent to 1].

loadFactor - the load factor to use to determine rehashing points [must be in (0.0, 1.0] range].

方法详细资料

toString

public String toString()

Overrides Object.toString() for debug purposes.

覆盖:

toString 在类中 Object

size

public int size()

Returns the number of key-value mappings in this map.

contains

public boolean contains(Object key)

get

public boolean get(Object key,
                   int[] out)

Returns the value that is mapped to a given 'key'. Returns false if this key has never been mapped.

参数:

key - mapping key [may not be null]

out - holder for the found value [must be at least of size 1]

返回:

'true' if this key was mapped to an existing value

keys

public Object[] keys()

put

public void put(Object key,
                int value)

Updates the table to map 'key' to 'value'. Any existing mapping is overwritten.

参数:

key - mapping key [may not be null]

value - mapping value.

remove

public void remove(Object key)

Updates the table to map 'key' to 'value'. Any existing mapping is overwritten.

参数:

key - mapping key [may not be null]
