V6104. A pattern was detected: A || (A && ...). The expression is excessive or contains a logical error.
The analyzer has detected an expression that can be reduced. Such redundancy may be a sign of a logical error.
Consider this example:
boolean firstCond, secondCond, thirdCond; .... if (firstCond || (firstCond && thirdCond)) ....
This expression is redundant. If 'firstCond == true', the condition will always be true regardless of what value the 'thirdCond' variable refers to; and if 'firstCond == false', the condition will always be false – again, irrespective of the 'thirdCond' variable. Thus, the expression 'firstCond || (firstCond && thirdCond)' can be simplified:
Perhaps the programmer made a mistake and wrote a wrong variable in the second subexpression. Then the correct version of this code should look like this:
if (firstCond || (secondCond && thirdCond))
