Method Detail

copy

StateSetBackingSet copy()

Returns:

a deep copy of this set.

contains

boolean contains(short id)

Analogous to Set.contains(Object).

add

boolean add(short id)

Analogous to Set.add(Object).

addBatch

void addBatch(short id)

Add a value in batch mode. After calling this method, the set is in "add batch mode" until StateSetBackingSet.addBatchFinish() is called. The purpose of this is to allow more efficient add operations that temporarily break the set's consistency. While this mode is active, other methods are not guaranteed to work correctly!

Parameters:

id - the id to add to the set.

addBatchFinish

void addBatchFinish()

Stop "add batch mode". This method will restore the set to a sane state after a batch add operation.

replace

void replace(short oldId,
             short newId)

Efficient version of remove(oldId); add(newId). This method assumes that the set contains oldId and the set does not contain newId!

Parameters:

oldId - id to remove. Assumed to be contained in the set.

newId - id to add. Assumed to be absent in the set.

remove

boolean remove(short id)

Analogous to Set.remove(Object).

clear

void clear()

Analogous to Set.clear() .

isDisjoint

boolean isDisjoint(StateSetBackingSet other)

Check whether this set is disjoint to another StateSetBackingSet.

Parameters:

other - the other backing set.

Returns:

true if this set is disjoint to the other set.

contains

boolean contains(StateSetBackingSet other)

Check whether this set is contains all entries of another StateSetBackingSet.

Parameters:

other - the other backing set.

Returns:

true if this set contains the other set.

iterator

PrimitiveIterator.OfInt iterator()

Specified by:

iterator in interface Iterable<Integer>
