From source file:google.registry.model.domain.fee.FeeExtensionCommandDescriptor.java

public CommandName getCommand() {
    // Require the xml string to be lowercase.
    if (command != null && CharMatcher.javaLowerCase().matchesAllOf(command)) {

        } catch (IllegalArgumentException e) {
            // Swallow this and return UNKNOWN below because there's no matching CommandName.
        }
    }
    return CommandName.UNKNOWN;

/**
 * Processes the case of the proto file name in the same fashion as the objective_c generator's

 *
 * Examples:
 *   - j2objc_descriptor -> J2ObjcDescriptor (notice that O is uppercase after the 2)
