in - DataInput to deseriablize this object from.
Throws:
IOException

write

public void write(DataOutput out)
           throws IOException
Description copied from interface: Writable
Serialize the fields of this object to out.

Specified by:
write in interface Writable
Parameters:
out - DataOuput to serialize this object into.
Throws:
IOException

equals

public boolean equals(Object o)
Returns true iff o is a IntWritable with the same value.

Overrides:
equals in class Object

hashCode

public int hashCode()
Overrides:
hashCode in class Object

compareTo

public int compareTo(IntWritable o)
Compares two IntWritables.

Specified by:
compareTo in interface Comparable<IntWritable>

toString

public String toString()
Overrides:
toString in class Object
