CollapsibleIfStatements

CollapsibleIfStatements

Sometimes two consecutive ‘if’ statements can be consolidated by separating their conditions with a boolean short-circuit operator.


                
//IfStatement[@Else='false']/Statement
 /IfStatement[@Else='false']
 |
//IfStatement[@Else='false']/Statement
 /Block[count(BlockStatement)=1]/BlockStatement
  /Statement/IfStatement[@Else='false']

Example(s):


  
void bar() {
	if (x) {			// original implementation
		if (y) {
			// do stuff
		}
	}
}

void bar() {
	if (x && y) {		// optimized implementation
		// do stuff
	}
}
