Package org.elasticsearch.common.collect

Class ImmutableOpenIntMap<VType>

java.lang.Object

org.elasticsearch.common.collect.ImmutableOpenIntMap<VType>

All Implemented Interfaces:

java.lang.Iterable<com.carrotsearch.hppc.cursors.IntObjectCursor<VType>>

public final class ImmutableOpenIntMap<VType>
extends java.lang.Object
implements java.lang.Iterable<com.carrotsearch.hppc.cursors.IntObjectCursor<VType>>

An immutable map implementation based on open hash map.

Can be constructed using a builder(), or using builder(org.elasticsearch.common.collect.ImmutableOpenIntMap) (which is an optimized option to copy over existing content and modify it).

Method Detail

get

public VType get(int key)

Returns:

Returns the value associated with the given key or the default value for the key type, if the key is not associated with any value.

Important note: For primitive type values, the value returned for a non-existing key may not be the default value of the primitive type (it may be any value previously assigned to that slot).

containsKey

public boolean containsKey(int key)

Returns true if this container has an association to a value for the given key.

size

public int size()

Returns:

Returns the current size (number of assigned keys) in the container.

isEmpty

public boolean isEmpty()

Returns:

Return true if this hash map contains no assigned keys.

iterator

public java.util.Iterator<com.carrotsearch.hppc.cursors.IntObjectCursor<VType>> iterator()

Returns a cursor over the entries (key-value pairs) in this map. The iterator is implemented as a cursor and it returns the same cursor instance on every call to Iterator.next(). To read the current key and value use the cursor's public fields. An example is shown below.

 for (IntShortCursor c : intShortMap)
 {
     System.out.println("index=" + c.index
       + " key=" + c.key
       + " value=" + c.value);
 }
 

The index field inside the cursor gives the internal index inside the container's implementation. The interpretation of this index depends on to the container.

Specified by:

iterator in interface java.lang.Iterable<VType>

keys

public com.carrotsearch.hppc.IntLookupContainer keys()

Returns a specialized view of the keys of this associated container. The view additionally implements ObjectLookupContainer.

keysIt

public java.util.Iterator<java.lang.Integer> keysIt()

Returns a direct iterator over the keys.

values

public com.carrotsearch.hppc.ObjectContainer<VType> values()

Returns:

Returns a container with all values stored in this map.

valuesIt

public java.util.Iterator<VType> valuesIt()

Returns a direct iterator over the keys.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:
