Constructor Details

CharSegmentedSortedMultiset

public CharSegmentedSortedMultiset(int leafSize)

Create a CharSegmentedSortedArray with the given leafSize.

Parameters:

leafSize - the maximumSize for any leaf

Method Details

insert

public boolean insert(WritableChunk<? extends Attributes.Values> valuesToInsert,
 WritableIntChunk<Attributes.ChunkLengths> counts)

Description copied from interface: SegmentedSortedMultiSet

Insert new valuesToInsert into this SSMS. The valuesToInsert to insert must be sorted, without duplicates. The valuesToInsert and counts chunks will be modified during this call, and the resulting chunks are undefined.

Specified by:

insert in interface SegmentedSortedMultiSet<Character>

Parameters:

valuesToInsert - the valuesToInsert to insert

counts - the number of times each value occurs

Returns:

true if any new values were inserted

remove

public boolean remove(SegmentedSortedMultiSet.RemoveContext removeContext,
 WritableChunk<? extends Attributes.Values> valuesToRemove,
 WritableIntChunk<Attributes.ChunkLengths> counts)

Remove valuesToRemove from this SSA. The valuesToRemove to remove must be sorted.

Specified by:

remove in interface SegmentedSortedMultiSet<Character>

Parameters:

valuesToRemove - the valuesToRemove to remove

removeContext - removalContext

Returns:

true if any values were removed.

validate

@VisibleForTesting
public void validate()

totalSize

public long totalSize()

Specified by:

totalSize in interface SegmentedSortedMultiSet<Character>

Returns:

the total size of the set in elements (i.e. if A exists twice, 2 is returned not one)

getNodeSize

public int getNodeSize()

Specified by:

getNodeSize in interface SegmentedSortedMultiSet<Character>

getMin

public Character getMin()

Specified by:

getMin in interface SegmentedSortedMultiSet<Character>

getMax

public Character getMax()

Specified by:

getMax in interface SegmentedSortedMultiSet<Character>

getMinChar

public char getMinChar()

getMinCount

public long getMinCount()

Specified by:

getMinCount in interface SegmentedSortedMultiSet<Character>

Returns:

the number of times the minimum value exists in this SSM.

getMaxChar

public char getMaxChar()

getMaxCount

public long getMaxCount()

Specified by:

getMaxCount in interface SegmentedSortedMultiSet<Character>

Returns:

the number of times the maximum value exists in this SSM.

moveFrontToBack

public void moveFrontToBack(SegmentedSortedMultiSet untypedDestination,
 long count)

Description copied from interface: SegmentedSortedMultiSet

Remove count elements from the front of this SSM and add them to the back of the destination SSM.

The minimum element of this SSM must be greater than or equal to the maximum of destination.

Specified by:

moveFrontToBack in interface SegmentedSortedMultiSet<Character>

Parameters:

untypedDestination - the SegmentedSortedMultiSet to append count elements to

count - how many elements to move to the destination

moveBackToFront

public void moveBackToFront(SegmentedSortedMultiSet untypedDestination,
 long count)

Description copied from interface: SegmentedSortedMultiSet

Remove count elements from the back of this SSM and add them to the front of the destination SSM.

The minimum element of this SSM must be less than or equal to the maximum of destination.

Specified by:

moveBackToFront in interface SegmentedSortedMultiSet<Character>

Parameters:

untypedDestination - the SegmentedSortedMultiSet to prepend count elements to

count - how many elements to move to the destination
