public IntWritable()

IntWritable

public IntWritable(int value)

Method Detail

set

public void set(int value)

Set the value of this IntWritable.

get

public int get()

Return the value of this IntWritable.

readFields

public void readFields(DataInput in)
                throws IOException

Description copied from interface: Writable

Deserialize 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

Parameters:

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
