Constructor Detail

ListStringSplit

public ListStringSplit(List<List<String>> data)

Method Detail

length

public long length()

Length of the split

Specified by:

length in interface InputSplit

Returns:

locations

public URI[] locations()

Locations of the splits

Specified by:

locations in interface InputSplit

Returns:

locationsIterator

public Iterator<URI> locationsIterator()

Specified by:

locationsIterator in interface InputSplit

locationsPathIterator

public Iterator<String> locationsPathIterator()

Specified by:

locationsPathIterator in interface InputSplit

reset

public void reset()

Description copied from interface: InputSplit

Reset the InputSplit without reinitializing it from scratch. In many cases, this is a no-op. For InputSplits that have randomization: reset should shuffle the order.

Specified by:

reset in interface InputSplit

write

public void write(DataOutput out)
           throws IOException

Serialize the fields of this object to out.

Specified by:

write in interface Writable

Parameters:

out - DataOuput to serialize this object into.

Throws:

IOException

readFields

public void readFields(DataInput in)
                throws IOException

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

toDouble

public double toDouble()

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

Specified by:

toDouble in interface Writable

toFloat

public float toFloat()

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

Specified by:

toFloat in interface Writable

toInt

public int toInt()

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

Specified by:

toInt in interface Writable

toLong

public long toLong()

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

Specified by:

toLong in interface Writable

getType

public WritableType getType()

Specified by:

getType in interface Writable

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

getData

public List<List<String>> getData()
