Class UnnecessaryLambdaArgumentParentheses

  • All Implemented Interfaces:
    com.google.errorprone.bugpatterns.BugChecker.LambdaExpressionTreeMatcher, com.google.errorprone.matchers.Suppressible, java.io.Serializable
    @AutoService(com.google.errorprone.bugpatterns.BugChecker.class)
public final class UnnecessaryLambdaArgumentParentheses
extends com.google.errorprone.bugpatterns.BugChecker
implements com.google.errorprone.bugpatterns.BugChecker.LambdaExpressionTreeMatcher
    UnnecessaryLambdaArgumentParentheses provides similar functionality to the upstream UnnecessaryParentheses, but specifically for single-parameter lambda arguments which are not covered by the existing check. Perhaps this can be contributed upstream. There's an argument against combining the two because parentheses around lambda arguments cannot be parsed directly from the AST where other parenthesis checked by UnnecessaryParentheses can.
