class UnnecessaryIfStatementRule
extends AbstractAstVisitorRule

Rule that checks for unnecessary if statements. If/else statements are considered unnecessary for the three scenarios described below.

(1) When the if and else blocks contain only an explicit return of true and false constants. These cases can be replaced by a simple return statement. Examples include:

(2) When the if statement is the last statement in a block and the if and else blocks contain only true and false expressions. This is an implicit return of true/false. For example, the if statement in the following code can be replaced by someExpression: boolean myMethod() { doSomething() if (someExpression) true; else false } (3) When either the if block or else block of an if statement that is not the last statement in a block contain only a single constant or literal expression For example, the if statement in the following code has no effect and can be removed: def myMethod() { if (someExpression) { 123 } doSomething() }
