Method Detail

add

public void add(Long value)

Consider using add(long) instead for primitive long values

Specified by:

add in interface Accumulator<Long,Long>

Parameters:

value - The value to add to the accumulator object

getLocalValue

public Long getLocalValue()

Specified by:

getLocalValue in interface Accumulator<Long,Long>

Returns:

local The local value from the current UDF context

merge

public void merge(Accumulator<Long,Long> other)

Description copied from interface: Accumulator

Used by system internally to merge the collected parts of an accumulator at the end of the job.

Specified by:

merge in interface Accumulator<Long,Long>

Parameters:

other - Reference to accumulator to merge in.

resetLocal

public void resetLocal()

Description copied from interface: Accumulator

Reset the local value. This only affects the current UDF context.

Specified by:

resetLocal in interface Accumulator<Long,Long>

clone

public LongMinimum clone()

Description copied from interface: Accumulator

Duplicates the accumulator. All subclasses need to properly implement cloning and cannot throw a CloneNotSupportedException

Specified by:

clone in interface Accumulator<Long,Long>

Overrides:

clone in class Object

Returns:

The duplicated accumulator.

add

public void add(long value)

getLocalValuePrimitive

public long getLocalValuePrimitive()

toString

public String toString()

Overrides:

toString in class Object
