Method Detail

build

public ImmutableBitSet build()

Builds an ImmutableBitSet from the contents of this Builder.

After calling this method, the Builder cannot be used again.

build

public ImmutableBitSet build(ImmutableBitSet bitSet)

Builds an ImmutableBitSet from the contents of this Builder, using an existing ImmutableBitSet if it happens to have the same contents.

Supplying the existing bit set if useful for set operations, where there is a significant chance that the original bit set is unchanged. We save memory because we use the same copy. For example:

 ImmutableBitSet primeNumbers;
 ImmutableBitSet hundreds = ImmutableBitSet.of(100, 200, 300);
 return primeNumbers.except(hundreds);

After calling this method, the Builder cannot be used again.

set

public ImmutableBitSet.Builder set(int bit)

trim

private void trim(int wordCount)

clear

public ImmutableBitSet.Builder clear(int bit)

wouldEqual

public boolean wouldEqual(ImmutableBitSet bitSet)

Returns whether the bit set that would be created by this Builder would equal a given bit set.

cardinality

public int cardinality()

Returns the number of set bits.

addAll

public ImmutableBitSet.Builder addAll(ImmutableBitSet bitSet)

Sets all bits in a given bit set.

addAll

public ImmutableBitSet.Builder addAll(java.lang.Iterable<java.lang.Integer> integers)

Sets all bits in a given list of bits.

addAll

public ImmutableBitSet.Builder addAll(ImmutableIntList integers)

Sets all bits in a given list of ints.

removeAll

public ImmutableBitSet.Builder removeAll(ImmutableBitSet bitSet)

Clears all bits in a given bit set.

set

public ImmutableBitSet.Builder set(int fromIndex,
                                   int toIndex)

Sets a range of bits, from from to to - 1.
