Constructor Detail

LongWritable

public LongWritable()

LongWritable

public LongWritable(long value)

Method Detail

set

public void set(long value)

Set the value of this LongWritable.

get

public long get()

Return the value of this LongWritable.

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

writeType

public void writeType(DataOutput out)
               throws IOException

Description copied from interface: Writable

Write the type (a single short value) to the DataOutput. See WritableFactory for details.

Specified by:

writeType in interface Writable

Parameters:

out - DataOutput to write to

Throws:

IOException - For errors during writing

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

fuzzyEquals

public boolean fuzzyEquals(Writable o,
                           double tolerance)

equals

public boolean equals(Object o)

Returns true iff o is a LongWritable 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 LongWritables.

Specified by:

compareTo in interface Comparable

toString

public String toString()

Overrides:

toString in class Object

toDouble

public double toDouble()

Description copied from interface: Writable

Convert Writable to double. Whether this is supported depends on the specific writable.

Specified by:

toDouble in interface Writable

toFloat

public float toFloat()

Description copied from interface: Writable

Convert Writable to float. Whether this is supported depends on the specific writable.

Specified by:

toFloat in interface Writable

toInt

public int toInt()

Description copied from interface: Writable

Convert Writable to int. Whether this is supported depends on the specific writable.

Specified by:

toInt in interface Writable

toLong

public long toLong()

Description copied from interface: Writable

Convert Writable to long. Whether this is supported depends on the specific writable.

Specified by:

toLong in interface Writable

getType

public WritableType getType()

Description copied from interface: Writable

Get the type of the writable.

Specified by:

getType in interface Writable

Returns:
