Constructor Detail

ArrayListOfShortsWritable

public ArrayListOfShortsWritable()

Constructs an ArrayListOfIntsWritable object.

ArrayListOfShortsWritable

public ArrayListOfShortsWritable(int initialCapacity)

Constructs an empty list with the specified initial capacity.

Parameters:

initialCapacity - the initial capacity of the list

ArrayListOfShortsWritable

public ArrayListOfShortsWritable(short first,
                         short last)

Constructs a list populated with shorts in range [first, last).

Parameters:

first - the smallest short in the range (inclusive)

last - the largest short in the range (exclusive)

ArrayListOfShortsWritable

public ArrayListOfShortsWritable(ArrayListOfShortsWritable other)

Constructs a deep copy of the ArrayListOfShortsWritable object given as parameter.

Parameters:

other - object to be copied

ArrayListOfShortsWritable

public ArrayListOfShortsWritable(short[] arr)

Constructs a list from an array. Defensively makes a copy of the array.

Parameters:

arr - source array

Method Detail

readFields

public void readFields(DataInput in)
                throws IOException

Deserializes this object.

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 object.

Specified by:

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

Parameters:

out - where to write the raw byte representation

Throws:

IOException

toString

public String toString()

Overrides:

toString in class ArrayListOfShorts

fromArrayListOfShorts

public static ArrayListOfShortsWritable fromArrayListOfShorts(ArrayListOfShorts a)

Creates a Writable version of this list.

compareTo

public int compareTo(ArrayListOfShortsWritable obj)

Elementwise comparison. Shorter always comes before if it is a sublist of longer. No preference if both are empty.

Specified by:

compareTo in interface Comparable<ArrayListOfShortsWritable>

Parameters:

obj - other object this is compared against
