size - array size

Method Detail

readFields

public void readFields(DataInput in)
                throws IOException

Specified by:

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

Throws:

IOException

write

public void write(DataOutput out)
           throws IOException

Specified by:

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

Throws:

IOException

getClone

public short[] getClone()

Returns a deep copy of the array. The length of the returned array will always be the value size(). That is, trailing unused space in the underlying array will be trimmed.

getArray

public short[] getArray()

Returns a reference to the underlying array. Note that the underlying array may have length longer than the value of size().

setArray

public void setArray(short[] array)

Sets the underlying array.

setArray

public void setArray(short[] array,
            int length)

Sets the underlying array and a specified length.

get

public short get(int i)

Returns the value at index i. Note that no bounds checking is performed.

Parameters:

i - index position

set

public void set(int i,
       short v)

Sets the value at index i.

Parameters:

i - position in array

v - value

size

public int size()

Returns the size of the float array.

toString

public String toString()

Overrides:

toString in class Object
