BufferManager.CloseableSortingBufferWithDuplicates

protected BufferManager.CloseableSortingBufferWithDuplicates(String name,
                                                  boolean onHeap,
                                                  NavigableMap<BufferManager.UniqueKey<K>,V> buffer)

Method Detail

isEmpty

public boolean isEmpty()

Description copied from interface: BufferManager.Buffer

Determine if this buffer is empty. This may be more efficient than BufferManager.Buffer.size().

Specified by:

isEmpty in interface BufferManager.Buffer

Returns:

true if the buffer is empty, or false otherwise

size

public long size()

Description copied from interface: BufferManager.Buffer

Get the size of the buffer. This might be more expensive if the buffer is not created with the flag to keep the size.

Specified by:

size in interface BufferManager.Buffer

Returns:

the size of the buffer.

put

public void put(K sortable,
       V record)

Description copied from interface: BufferManager.SortingBuffer

Put the supplied value into the buffer given its sortable value.

Specified by:

put in interface BufferManager.SortingBuffer<K extends Comparable<K>,V>

Parameters:

sortable - the value of the record that is to be used for sorting

record - the record

getAll

public Iterator<V> getAll(K key)

Description copied from interface: BufferManager.SortingBuffer

Get an iterator over all of the records that have the given sortable value.

Specified by:

getAll in interface BufferManager.SortingBuffer<K extends Comparable<K>,V>

Parameters:

key - the sortable value

Returns:

the iterator; null if there is no entry, or an iterator with one or more values

getAll

public Iterator<V> getAll(K lowerKey,
                 boolean includeLowerKey,
                 K upperKey,
                 boolean includeUpperKey)

Description copied from interface: BufferManager.SortingBuffer

Get an iterator over all of the records that have a sortable value with in the specified range.

Specified by:

getAll in interface BufferManager.SortingBuffer<K extends Comparable<K>,V>

Parameters:

lowerKey - the minimum sortable value; may be null if there is no minimum

includeLowerKey - true if the values equal to or greater than lowerKey value is to be included, or false if only values greater than lowerKey should be included

upperKey - the maximum sortable value; may be null if there is no maximum

includeUpperKey - true if the values equal to or less than upperKey value are to be included, or false if only values less than upperKey should be included

Returns:

the iterator; null if there is no entry, or an iterator with one or more values

ascending

public Iterator<V> ascending()

Description copied from interface: BufferManager.SortingBuffer

Get an iterator over all of the records in ascending order.

Specified by:

ascending in interface BufferManager.SortingBuffer<K extends Comparable<K>,V>

Returns:

the ascending iterator

descending

public Iterator<V> descending()

Description copied from interface: BufferManager.SortingBuffer

Get an iterator over all of the records in descending order.

Specified by:

descending in interface BufferManager.SortingBuffer<K extends Comparable<K>,V>

Returns:

the ascending iterator

toString

public String toString()

Overrides:

toString in class Object
