Creates a String2IntOpenHashMapWritable object.

Method Detail

readFields

public void readFields(DataInput in)
                throws IOException

Deserializes the map.

Specified by:

readFields in interface org.apache.hadoop.io.Writable

Parameters:

in - source for raw byte representation

Throws:

IOException

write

public void write(DataOutput out)
           throws IOException

Specified by:

write in interface org.apache.hadoop.io.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 org.apache.hadoop.io.Writable> Object2IntOpenHashMapWritable<K> create(DataInput in)
                                                                                         throws IOException

Creates object from serialized representation.

Parameters:
