Field Detail

m_cMaxSize

protected int m_cMaxSize

The maximum size of this partial result.

m_comparator_copy

protected Comparator<? super E> m_comparator_copy

The comparator used to compare logical elements. Developers should NOT rely on this field, rely on TopNAggregator.m_comparator instead as this field will eventually be removed.

Constructor Detail

PartialResult

public PartialResult()

Default constructor.

PartialResult

public PartialResult(Comparator<? super E> comparator,
                     int cMaxSize)

Construct a PartialResult using the specified comparator.

Parameters:

comparator - the comparator

cMaxSize - the maximum size of this partial result

Method Detail

merge

public TopNAggregator.PartialResult<E> merge(TopNAggregator.PartialResult<E> result)

Merge single PartialResult into this PartialResult.

Parameters:

result - the partial result to merge

Returns:

this PartialResult

addAll

public void addAll(Iterator<E> iterValues)

Add all specified values to this PartialResult.

Parameters:

iterValues - the values to add

add

public boolean add(E value)

Description copied from class: SortedBag

Specified by:

add in interface Collection<E>

Overrides:

add in class SortedBag<E>

readExternal

public void readExternal(DataInput in)
                  throws IOException

Description copied from interface: ExternalizableLite

Specified by:

readExternal in interface ExternalizableLite

Parameters:

in - the DataInput stream to read data from in order to restore the state of this object

Throws:

IOException - if an I/O exception occurs

NotActiveException - if the object is not in its initial state, and therefore cannot be deserialized into

Specified by:

readExternal in interface PortableObject

Parameters:

in - the PofReader from which to read the object's state

Throws:

IOException - if an I/O error occurs

writeExternal

public void writeExternal(PofWriter out)
                   throws IOException

Description copied from interface: PortableObject
