类 IntObjectMap

java.lang.Object

com.vladium.util.IntObjectMap

所有已实现的接口:

Serializable

public final class IntObjectMap
extends Object
implements Serializable

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.

IntObjectMap

public IntObjectMap()

Equivalent to IntObjectMap(11, 0.75F).

IntObjectMap

public IntObjectMap(int initialCapacity)

Equivalent to IntObjectMap(capacity, 0.75F).

IntObjectMap

public IntObjectMap(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(int key)

get

public Object get(int key)

Returns the value that is mapped to a given 'key'. Returns null if (a) this key has never been mapped or (b) it has been mapped to a null value.

参数:

key - mapping key

返回:

Object value mapping for 'key' [can be null].

keys

public int[] keys()

put

public Object put(int key,
                  Object value)

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

参数:

key - mapping key

value - mapping value [can be null].

返回:

Object previous value mapping for 'key' [can be null]
