Do Boolean functions "fail fast"?
Will @and(expression_1, expression_2, expression_3) return a false result when the first expression (from left to right) evaluates as false, or are all expressions evaluated before a result is returned?
Similarly will @or(expression_1, expression_2, expression_3) return a true result when the first expression (from left to right) evaluates as true, or are all expressions evaluated before a result is returned?
For @if(expression_1, expression_2, expression_3), are both expression_2 and expression_3 always evaluated, or is only the expression that corresponds to the results of expression_1 evaluated?
Also, is there any difference or preference to using @and(A, B) over A && B, or @or(A, B) over A || B ?

Hi,
I don't think there will any difference/preference in using (@and , && ), (@or,||)
If you check the generated java code for the above funcitons :
Also, i think, it usually evaluates first expression, and if it returns false, in case @and, it wont check the other parameters passed. It jus simply returns false.
