/**
* Check the whitespace between two tokens, throw an error if it doesn't match the
* expected whitespace and if relevant, fix it.
*
* Note:
* - This method will not auto-fix if there is anything but whitespace between the two
* tokens. In that case, it will throw a non-fixable error/warning.
* - If `'newline'` is expected and _no_ new line is encountered, a new line will be added,
* but no assumptions will be made about the intended indentation of the code.
* This should be handled by a (separate) indentation sniff.
* - If `'newline'` is expected and multiple new lines are encountered, this will be accepted
* as valid.
* No assumptions are made about whether additional blank lines are allowed or not.
* If _exactly_ one line is desired, combine this fixer with the {@see \PHPCSUtils\Fixers\BlankLineFixer}
* (upcoming).
* - The fixer will not leave behind any trailing spaces on the original line when fixing
* to `'newline'`, but it will not correct _existing_ trailing spaces when there already
* is a new line in place.
* - This method can optionally record a metric for this check which will be displayed
* when the end-user requests the "info" report.
*
* @since 1.0.0
*
* @param \PHP_CodeSniffer\Files\File $phpcsFile The file being scanned.
* @param int $stackPtr The position of the token which should be used
* when reporting an issue.
* @param int $secondPtr The stack pointer to the second token.
* This token can be before or after the `$stackPtr`,
* but should only be separated from the `$stackPtr`
* by whitespace and/or comments/annotations.
* @param string|int $expectedSpaces Number of spaces to enforce.
* Valid values:
* - (int) Number of spaces. Must be `0` or more.
* - (string) `'newline'`.
* @param string $errorTemplate Error message template.
* Note: _The placeholder replacement phrase will be
* in human readable English and include "spaces"/
* "new line", so no need to include that in the template._
* This string should contain two placeholders:
* - `%1$s` = expected spaces phrase.
* - `%2$s` = found spaces phrase.
* @param string $errorCode A violation code unique to the sniff message.
* Defaults to `"Found"`.
* It is strongly recommended to change this if
* this fixer is used for different errors in the
* same sniff.
* @param string $errorType Optional. Whether to report the issue as a
* `"warning"` or an `"error"`. Defaults to `"error"`.
* @param int $errorSeverity Optional. The severity level for this message.
* A value of `0` will be converted into the default
* severity level.
* @param string $metricName Optional. The name of the metric to record.
* This can be a short description phrase.
* Leave empty to not record metrics.
*
* @return void
*
* @throws \PHP_CodeSniffer\Exceptions\RuntimeException If the tokens passed do not exist or are whitespace
* tokens.
* @throws \PHP_CodeSniffer\Exceptions\RuntimeException If `$expectedSpaces` is not a valid value.
* @throws \PHP_CodeSniffer\Exceptions\RuntimeException If the tokens passed are separated by more than just
* empty (whitespace + comments/annotations) tokens.
