Class SimplifyBooleanExpressionCheck

Implemented Interfaces:
Configurable, Contextualizable

public class SimplifyBooleanExpressionCheck
extends Check

Checks for overly complicated boolean expressions. Currently finds code like if (b == true), b || true, !false, etc.

Rationale: Complex boolean logic makes code hard to understand and maintain.

An example of how to configure the check is:

 <module name="SimplifyBooleanExpression"/>
