ALTERNATIVE_OPERATOR_NAMES back to summary

ALTERNATIVE_OPERATOR_NAMES	back to summary
private static final String[] ALTERNATIVE_OPERATOR_NAMES Alternative textual operator names which must match enum constant names in `TokenKind`. Note that `AND` and `OR` are also alternative textual names, but they are handled later in `InternalSpelExpressionParser`. If this list gets changed, it must remain sorted since we use it with `Arrays#binarySearch(Object[], Object)`.

private static final String[] ALTERNATIVE_OPERATOR_NAMES

Note that AND and OR are also alternative textual names, but they are handled later in InternalSpelExpressionParser.

If this list gets changed, it must remain sorted since we use it with Arrays#binarySearch(Object[], Object).
