Class TripleOfIntsString

java.lang.Object

edu.umd.cloud9.io.triple.TripleOfIntsString

All Implemented Interfaces:

Comparable<TripleOfIntsString>, org.apache.hadoop.io.Writable, org.apache.hadoop.io.WritableComparable<TripleOfIntsString>

public class TripleOfIntsString
extends Object
implements org.apache.hadoop.io.WritableComparable<TripleOfIntsString>

WritableComparable representing a pair of integers. The elements in the pair are referred to as the left and right elements. The natural sort order is: first by the left element, and then by the right element.

Constructor Detail

TripleOfIntsString

public TripleOfIntsString()

Creates a ThreeInts instance.

TripleOfIntsString

public TripleOfIntsString(int left,
                  int middle,
                  String right)

Creates a pair.

Parameters:

left - the left element

middle - the middle element

right - the right element

Method Detail

readFields

public void readFields(DataInput in)
                throws IOException

Deserializes this ThreeInts instance.

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

Serializes this ThreeInts instance.

Specified by:

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

Parameters:

out - where to write the raw byte representation

Throws:

IOException

getLeftElement

public int getLeftElement()

Returns the left element.

Returns:

the left element

getMiddleElement

public int getMiddleElement()

Returns the middle element.

Returns:

the middle element

getRightElement

public String getRightElement()

Returns the right element.

Returns:

the right element

set

public void set(int left,
       int middle,
       String right)

Sets the right and left elements of this pair.

Parameters:

left - the left element

middle - the middle element

right - the right element

equals

public boolean equals(Object obj)

Checks two ThreeInts for equality.

Overrides:

equals in class Object

Parameters:

obj - object for comparison

Returns:

true if obj is equal to this object, false otherwise

compareTo

public int compareTo(TripleOfIntsString obj)

Defines a natural sort order for pairs. Pairs are sorted first by the left element, and then by the right element.

Specified by:

compareTo in interface Comparable<TripleOfIntsString>

Returns:

a value less than zero, a value greater than zero, or zero if this pair should be sorted before, sorted after, or is equal to obj.

hashCode

public int hashCode()

Returns a hash code value for this ThreeInts instance.

Overrides:

hashCode in class Object

Returns:

hash code for this ThreeInts instance

toString

public String toString()

Generates human-readable String representation of this pair.

Overrides:

toString in class Object

Returns:

human-readable String representation of this pair

clone

public TripleOfIntsString clone()

Clones this object.

Overrides:

clone in class Object

Returns:

clone of this object
