BitDef.class documentation

Documentation

BitDefs.class is a class that represents the individual bit positions for integer bits 1-32. These constants are used to generate bitwise bitmasks. BIT1,BIT2,BIT3,...etc. to BIT32.
Example:                                 // To see if a bit is set
int bitMask = BitDefs.BIT1; // Bit 1 is set

   if((bitMask & BitDefs.BIT1)!=0)
   {
      // do something
   }
   //To set a bit you OR in the bit
bitMask |= bitMask.BIT1;                                  // Or in the bit
   //To unset a bit AND it with its exclusive OR mask
bitMask &= ~BitDefs.BIT1; /           / And with Exclusive OR of Bit1

//Check multiple bits by making a compare mask

int compareMask = BitDefs.BIT1|BitDefs.BIT2|BitDefs.BIT3;

   if((compareMask & bitMask)!=0) // Check all bits
   {
      // do somethng
   }
