Data Structures
struct ANTLR3_BITSET_LIST_struct

Macros
#define ANTLR3_BITSET_BITS 64
How many bits in the elements.
#define ANTLR3_BITSET_LOG_BITS 6
log2 of ANTLR3_BITSET_BITS 2^ANTLR3_BITSET_LOG_BITS = ANTLR3_BITSET_BITS
#define ANTLR3_BITSET_MOD_MASK ANTLR3_BITSET_BITS - 1
We will often need to do a mod operator (i mod nbits).
#define ANTLR3_BITSET_NIBBLE 4
How many bits in a nible of bits.

Detailed Description
Defines the basic structures of an ANTLR3 bitset.
this is a C version of the cut down Bitset class provided with the java version of antlr 3.

#define ANTLR3_BITSET_MOD_MASK ANTLR3_BITSET_BITS - 1
We will often need to do a mod operator (i mod nbits). For powers of two, this mod operation is the same as:
- (i & (nbits-1)).
Since mod is relatively slow, we use an easily precomputed mod mask to do the mod instead.

#define ANTLR3_BITSET_NIBBLE 4
How many bits in a nible of bits.
