Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`BitKey`	`and(BitKey bitKey)` Returns the boolean AND of this bitkey and the given bitkey.
`BitKey`	`andNot(BitKey bitKey)` Returns a `BitKey` containing all of the bits in this `BitSet` whose corresponding bit is NOT set in the specified `BitSet`.
`int`	`cardinality()` Returns the number of bits set.
`void`	`clear()` Sets all of the bits in this BitKey to `false`.
`void`	`clear(int pos)` Sets the bit specified by the index to `false`.
`int`	`compareTo(BitKey bitKey)`
`protected int`	`compareToBig(BitKey.Big that)`
`BitKey`	`copy()` Returns a copy of this BitKey.
`BitKey`	`emptyCopy()` Returns an empty BitKey of the same type.
`boolean`	`equals(Object o)`
`boolean`	`get(int pos)` Returns the value of the bit with the specified index.
`int`	`hashCode()`
`boolean`	`intersects(BitKey bitKey)` Returns whether this BitKey has any bits in common with a given BitKey.
`boolean`	`isEmpty()` Returns true if this `BitKey` contains no bits that are set to `true`.
`boolean`	`isSuperSetOf(BitKey bitKey)` Is every bit set in the parameter `bitKey` also set in `this`.
`Iterator<Integer>`	`iterator()` To say that I am happy about this algorithm (or the variations of the algorithm used for the Mid128 and Big BitKey implementations) would be a stretch.
`int`	`nextSetBit(int fromIndex)` Returns the index of the first bit that is set to `true` that occurs on or after the specified starting index.
`BitKey`	`or(BitKey bitKey)` Or the parameter `BitKey` with `this`.
`BitKey`	`orNot(BitKey bitKey)` XOr the parameter `BitKey` with `this`.
`void`	`set(int pos)` Sets the bit at the specified index to `true`.
`BitSet`	`toBitSet()` Returns a `BitSet` with the same contents as this BitKey.
`String`	`toString()`

- Method Detail
  - set
```
public void set(int pos)
```
    Description copied from interface: BitKey
    
    Sets the bit at the specified index to true.
  - get
```
public boolean get(int pos)
```
    Description copied from interface: BitKey
    
    Returns the value of the bit with the specified index. The value is true if the bit with the index bitIndex is currently set in this BitKey; otherwise, the result is false.
  - clear
```
public void clear(int pos)
```
    Description copied from interface: BitKey
    
    Sets the bit specified by the index to false.
  - clear
```
public void clear()
```
    Description copied from interface: BitKey
    
    Sets all of the bits in this BitKey to false.
  - cardinality
```
public int cardinality()
```
    Description copied from interface: BitKey
    
    Returns the number of bits set.
    
    Returns:
    
    Number of bits set
  - or
```
public BitKey or(BitKey bitKey)
```
    Description copied from interface: BitKey
    
    Or the parameter BitKey with this.
    
    Parameters:
    
    bitKey - Bit key
  - orNot
```
public BitKey orNot(BitKey bitKey)
```
    Description copied from interface: BitKey
    
    XOr the parameter BitKey with this.
    
    Parameters:
    
    bitKey - Bit key
  - and
```
public BitKey and(BitKey bitKey)
```
    Description copied from interface: BitKey
    
    Returns the boolean AND of this bitkey and the given bitkey.
    
    Parameters:
    
    bitKey - Bit key
  - andNot
```
public BitKey andNot(BitKey bitKey)
```
    Description copied from interface: BitKey
    
    Returns a BitKey containing all of the bits in this BitSet whose corresponding bit is NOT set in the specified BitSet.
  - isSuperSetOf
```
public boolean isSuperSetOf(BitKey bitKey)
```
    Description copied from interface: BitKey
    
    Is every bit set in the parameter bitKey also set in this. If one switches this with the parameter bitKey one gets the equivalent of isSubSetOf.
    
    Parameters:
    
    bitKey - Bit key
  - intersects
```
public boolean intersects(BitKey bitKey)
```
    Description copied from interface: BitKey
    
    Returns whether this BitKey has any bits in common with a given BitKey.
  - toBitSet
```
public BitSet toBitSet()
```
    Description copied from interface: BitKey
    
    Returns a BitSet with the same contents as this BitKey.
  - iterator
```
public Iterator<Integer> iterator()
```
    To say that I am happy about this algorithm (or the variations of the algorithm used for the Mid128 and Big BitKey implementations) would be a stretch. It works but there has to be a more elegant and faster one but this is the best I could come up with in a couple of hours.
  - nextSetBit
```
public int nextSetBit(int fromIndex)
```
    Description copied from interface: BitKey
    Returns the index of the first bit that is set to true that occurs on or after the specified starting index. If no such bit exists then -1 is returned. To iterate over the true bits in a BitKey, use the following loop:
```
 for (int i = bk.nextSetBit(0); i >= 0; i = bk.nextSetBit(i + 1)) {
     // operate on index i here
 }
```
    Parameters:
    
    fromIndex - the index to start checking from (inclusive)
    
    Returns:
    
    the index of the next set bit
  - equals
```
public boolean equals(Object o)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - compareTo
```
public int compareTo(BitKey bitKey)
```
  - compareToBig
```
protected int compareToBig(BitKey.Big that)
```
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - copy
```
public BitKey copy()
```
    Description copied from interface: BitKey
    
    Returns a copy of this BitKey.
    
    Returns:
    
    copy of BitKey
  - emptyCopy
```
public BitKey emptyCopy()
```
    Description copied from interface: BitKey
    
    Returns an empty BitKey of the same type. This is the same as calling BitKey.copy() followed by BitKey.clear().
    
    Returns:
    
    BitKey of same type
  - isEmpty
```
public boolean isEmpty()
```
    Description copied from interface: BitKey
    
    Returns true if this BitKey contains no bits that are set to true.
