Braces RulesThe Braces Ruleset contains a collection of braces rules. IfStmtsMustUseBracesAvoid using if statements without using curly braces This rule is defined by the following XPath expression:
//IfStatement[count(*) < 3][not(Statement/Block)]
Here's an example of code that would trigger this rule:
public class Foo {
public void bar() {
int x = 0;
if (foo) x++;
}
}
WhileLoopsMustUseBracesRuleAvoid using 'while' statements without using curly braces This rule is defined by the following XPath expression:
//WhileStatement[not(Statement/Block)]
Here's an example of code that would trigger this rule:
public void doSomething() {
while (true)
x++;
}
IfElseStmtsMustUseBracesRuleAvoid using if..else statements without using curly braces This rule is defined by the following XPath expression:
//Statement
[parent::IfStatement]
[not(child::Block)]
[not(child::IfStatement)]
Here's an example of code that would trigger this rule:
public void doSomething() {
// this is OK
if (foo) x++;
// but this is not
if (foo)
x=x+1;
else
x=x-1;
}
ForLoopsMustUseBracesRuleAvoid using 'for' statements without using curly braces This rule is defined by the following XPath expression:
//ForStatement[not(Statement/Block)]
Here's an example of code that would trigger this rule:
public void foo() {
for (int i=0; i<42;i++)
foo();
}
