public class JavaOperatorTable extends BitwiseOperatorTable

An operator table which supports most of the operators which appear in Java. Includes ++x, x++, a?b:c, x+=y etc. and bitwise operators.

The full set added is: a&b, a|b, ~a, a^b, a>>b, a<<b a<<<b, x?y:z, ++x, --x, x++, x--, x+=y, x-=y, x*=y, x/=y, x%=y, x&=y, x|=y, x^=y, x<<=y, x>>=y, x<<<=y.

      Description copied from class: EmptyOperatorTable
      Create a new version of this OperatorTable. Operators are copied into new table. However, Operators whose pfmc implement JepComponent are duplicated. This means the table could be used in a separate thread without problem. Subclasses should override with method to return a table of the correct type, a typical implementation would be 
          @Override
    public OperatorTableI shallowCopy() {
        Map<OperatorKey, Operator> map = this.threadSafeMapCopy();
        return new MyOperatorTable(map);
    }
      using the EmptyOperatorTable.threadSafeMapCopy() method to return a copy of the map of operators and a constructor taking this map which uses the EmptyOperatorTable(Map) constructor.
      Specified by:
      shallowCopy in interface OperatorTableI
      Overrides:
      shallowCopy in class BitwiseOperatorTable
      Returns:
      a new Table
