StateSetBackingBitSet

public StateSetBackingBitSet(int stateIndexSize)

Method Detail

copy

public StateSetBackingSet copy()

Specified by:

copy in interface StateSetBackingSet

Returns:

a deep copy of this set.

contains

public boolean contains(short id)

Description copied from interface: StateSetBackingSet

Analogous to Set.contains(Object).

Specified by:

contains in interface StateSetBackingSet

add

public boolean add(short id)

Description copied from interface: StateSetBackingSet

Analogous to Set.add(Object).

Specified by:

add in interface StateSetBackingSet

addBatch

public void addBatch(short id)

Description copied from interface: StateSetBackingSet

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!

Specified by:

addBatch in interface StateSetBackingSet

Parameters:

id - the id to add to the set.

addBatchFinish

public void addBatchFinish()

Description copied from interface: StateSetBackingSet

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

Specified by:

addBatchFinish in interface StateSetBackingSet

replace

public void replace(short oldId,
                    short newId)

Description copied from interface: StateSetBackingSet

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

Specified by:

replace in interface StateSetBackingSet

Parameters:

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

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

remove

public boolean remove(short id)

Description copied from interface: StateSetBackingSet

Analogous to Set.remove(Object).

Specified by:

remove in interface StateSetBackingSet

clear

public void clear()

Description copied from interface: StateSetBackingSet

Analogous to Set.clear() .

Specified by:

clear in interface StateSetBackingSet

isDisjoint

public boolean isDisjoint(StateSetBackingSet other)

Description copied from interface: StateSetBackingSet

Check whether this set is disjoint to another StateSetBackingSet.

Specified by:

isDisjoint in interface StateSetBackingSet

Parameters:

other - the other backing set.

Returns:

true if this set is disjoint to the other set.

contains

public boolean contains(StateSetBackingSet other)

Description copied from interface: StateSetBackingSet

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

Specified by:

contains in interface StateSetBackingSet

Parameters:

other - the other backing set.

Returns:

true if this set contains the other set.

iterator

public PrimitiveIterator.OfInt iterator()

Specified by:

iterator in interface StateSetBackingSet

Specified by:

iterator in interface Iterable<Integer>

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
