All Implemented Interfaces:
Configurable, Contextualizable
public class NumericalPrefixesInfixesSuffixesCharacterCaseCheck extends AbstractCheck
Checks that all numerical literal prefixes, infixes, and suffixes are written using lowercase letters (for example prefixes : 0x, 0b, infixes : e, p, suffixes : f, d). This convention follows the OpenJDK Style Guide.

ATTENTION:

This check ignores the L suffix for long literals, as using an uppercase L is a widely accepted and recommended practice to avoid confusion with the digit 1.

Since:
13.2.0

    • getAcceptableTokens

      public int[] getAcceptableTokens()
      Description copied from class: AbstractCheck
      The configurable token set. Used to protect Checks against malicious users who specify an unacceptable token set in the configuration file. The default implementation returns the check's default tokens.
      Specified by:
      getAcceptableTokens in class AbstractCheck
      Returns:
      the token set this check is designed for.
