+----java.util.BitSet
- public final class BitSet
- extends Object
- implements Cloneable
A set of bits. The set automatically grows as more bits are
needed.
-
BitSet()
- Creates an empty set.
-
BitSet(int)
- Creates an empty set with the specified size.
-
and(BitSet)
- Logically ANDs this bit set with the specified set of bits.
-
clear(int)
- Clears a bit.
-
clone()
- Clones the BitSet.
-
equals(Object)
- Compares this object against the specified object.
-
get(int)
- Gets a bit.
-
hashCode()
- Gets the hashcode.
-
or(BitSet)
- Logically ORs this bit set with the specified set of bits.
-
set(int)
- Sets a bit.
-
size()
- Calculates and returns the set's size
-
toString()
- Converts the BitSet to a String.
-
xor(BitSet)
- Logically XORs this bit set with the specified set of bits.
BitSet
public BitSet()
