Set the value of this VIntWritable.

get

public int get()

Return the value of this VIntWritable.

readFields

public void readFields(DataInput in)
                throws IOException

Description copied from interface: Writable

Reads the fields of this object from in. For efficiency, implementations should attempt to re-use storage in the existing object where possible.

Specified by:

readFields in interface Writable

Throws:

IOException

write

public void write(DataOutput out)
           throws IOException

Description copied from interface: Writable

Writes the fields of this object to out.

Specified by:

write in interface Writable

Throws:

IOException

equals

public boolean equals(Object o)

Returns true iff o is a VIntWritable with the same value.

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

compareTo

public int compareTo(Object o)

Compares two VIntWritables.

Specified by:

compareTo in interface Comparable

toString

public String toString()

Overrides:

toString in class Object
