Specified by:

readFields in interface Writable

Parameters:

in - source for raw byte representation

Throws:

IOException

write

public void write(DataOutput out)
           throws IOException

Serializes the map.

Specified by:

write in interface Writable

Parameters:

out - where to write the raw byte representation

Throws:

IOException

serialize

public byte[] serialize()
                 throws IOException

Returns the serialized representation of this object as a byte array.

Returns:

byte array representing the serialized representation of this object

Throws:

IOException

create

public static <K extends Writable> Object2IntOpenHashMapWritable<K> create(DataInput in)
                                                                throws IOException

plus

public void plus(Object2IntOpenHashMapWritable<K> m)

Adds values of keys from another map to this map.

Parameters:

m - the other map

dot

public int dot(Object2IntOpenHashMapWritable<K> m)

Computes the dot product of this map with another map.

Parameters:

m - the other map

increment

public void increment(K key)
