public class BooleanListBitVector
extends AbstractBitVector
implements Serializable

A boolean-list based implementation of BitVector.

This implementation of a bit vector is based on a backing list of booleans. It is rather inefficient, but useful for wrapping purposes, for covering completely the code in AbstractBitVector and for creating mock objects.

Method Detail

ensureIntegerIndex

protected static final void ensureIntegerIndex(long index)

getInstance

public static BooleanListBitVector getInstance(long capacity)

getInstance

public static BooleanListBitVector getInstance()

Creates a new empty bit vector.

of

public static BooleanListBitVector of(int... bit)

Creates a new bit vector with given bits.

wrap

public static BooleanListBitVector wrap(BooleanList list)

wrap

public static BooleanListBitVector wrap(BooleanBigList list)

length

public long length()

Description copied from interface: BitVector

Returns the number of bits in this bit vector.

If the number of bits in this vector is smaller than or equal to Integer.MAX_VALUE, this method is semantically equivalent to List.size(). In any case, this method is semantically equivalent to Size64.size64(), but it is prefererred.

Specified by:

length in interface BitVector

Returns:

the number of bits in this bit vector.

set

public boolean set(long index,
                   boolean value)

Specified by:

set in interface BooleanBigList

Overrides:

set in class AbstractBitVector

getBoolean

public boolean getBoolean(long index)

Specified by:

getBoolean in interface BooleanBigList

add

public void add(long index,
                boolean value)

Specified by:

add in interface BooleanBigList

Overrides:

add in class AbstractBitVector

removeBoolean

public boolean removeBoolean(long index)

Specified by:

removeBoolean in interface BooleanBigList

Overrides:

removeBoolean in class AbstractBitVector

copy

public BooleanListBitVector copy(long from,
                                 long to)

Description copied from interface: BitVector

Returns a copy of a part of this bit vector.

Specified by:

copy in interface BitVector

Overrides:

copy in class AbstractBitVector

Parameters:

from - the starting bit, inclusive.

to - the ending bit, not inclusive.

Returns:

a copy of the part of this bit vector going from bit from (inclusive) to bit to (not inclusive)

copy

public BooleanListBitVector copy()

Description copied from interface: BitVector

Returns a copy of this bit vector.

Specified by:

copy in interface BitVector

Overrides:

copy in class AbstractBitVector

Returns:

a copy of this bit vector.

ensureCapacity

public BitVector ensureCapacity(long numBits)

length

public BitVector length(long numBits)

Description copied from interface: BitVector

Sets the number of bits in this bit vector.

It is expected that this method will try to allocate exactly the necessary space.

If the argument fits an integer, this method has the same side effects of BooleanList.size(int). In any case, this method has the same side effects of BigList.size(long), but it is preferred, as it has the advantage of returning this bit vector, thus making it possible to chain methods.

Specified by:

length in interface BitVector

Overrides:

length in class AbstractBitVector

Returns:

this bit vector.
