immutable class BOOL < $STR, $IS_EQ, $FMT |
---|
**** | BOOL objects represent boolean values and are either equal to `true' or `false'. The boolean operators `and' and `or' are part of the Sather language. This class defines several additional operators. |
$FMT | $IS_EQ | $STR |
and_not(b:SAME):SAME |
---|
**** | Computes self and the complement of `b'. |
and_rout(b:SAME):SAME |
---|
**** | A routine version of "self and `b'". (Useful for making bound routines.) |
fmt( f: STR ):STR |
---|
from_str(s:STR):SAME |
---|
implies(b:SAME):SAME |
---|
**** | True iff self implies `b'. Same as "nand_not". |
int:INT |
---|
**** | 0 for false, 1 for true |
is_eq(b:SAME):SAME |
---|
**** | True if self and `b' have the same value (same as "xnor"). |
nand(b:SAME):SAME |
---|
**** | The complement of self anded with `b'. |
nand_not(b:SAME):SAME |
---|
**** | Computes self nand the complement of `b'. This is the same as the complement of self or `b'. |
nor(b:SAME):SAME |
---|
**** | The complement of self ored with `b'. |
nor_not(b:SAME):SAME |
---|
**** | Computes self nor the complement of `b'. This is the same as the complement of self and `b'. |
not:SAME |
---|
**** | The complement of self. if self then return false else return true end |
or_not(b:SAME):SAME |
---|
**** | Computes self or the complement of `b'. |
or_rout(b:SAME):SAME |
---|
**** | A routine version of "self or `b'". (Useful for making bound routines.) |
str:STR |
---|
**** | The string representation of self. |
xnor(b:SAME):SAME |
---|
**** | True if self and `b' have the same value (same as "is_eq"). |
xor(b:SAME):SAME |
---|
**** | Self exclusive ored with `b'. Same as "/=". |
