CompositeSet class
A composite BitSet using multiple chunks of BitSet objects with offsets.
By default, each chunk is using a maximum cardinality of 2^16 entries, following the RoaringBitmap pattern.
Constructors
-
CompositeSet({int chunkBits = 16, List<
BitSetChunk> ? chunks})
Properties
- cardinality → int
-
The number of members.
no setteroverride
- chunkBits → int
-
The bits used for each chunk.
final
-
chunks
→ List<
BitSetChunk> -
The list of chunks.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- length → int
-
The largest addressable or contained member of the BitSet:
no setteroverride
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
and(
CompositeSet set) → void -
asIntIterable(
) → Iterable< int> -
Returns an iterable wrapper of the BitSet that iterates over the index
members that are set to true.
override
-
asUint32Iterable(
) → Iterable< int> -
Returns an iterable wrapper that returns the content of the BitSet as
32-bit int blocks. Members are iterated from a zero-based index and each
block contains 32 values as a bit index.
override
-
clone(
) → CompositeSet -
Creates a copy of the current BitSet.
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
optimize(
{BitArrayOptimizer? optimizer, int removeThreshold = 0}) → void - Optimize the containers.
-
or(
CompositeSet set) → void -
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
inherited
-
operator [](
int index) → bool -
Whether the value specified by the
indexis member of the collection.override -
operator []=(
int index, bool value) → void -
Sets the bit specified by the
indexto thevalue.
