     * Attaches the lowest alternative number type to the parameter number via {@link NumberWithFallbackType}, if
     * that's useful according the possible target number types. This transformation is applied on the method call
     * argument list before overloaded method selection.
     * 
     * 

Note that as of this writing, this method is only used when * {@link BeansWrapper#getIncompatibleImprovements()} >= 2.3.21. * *

Why's this needed, how it works: Overloaded method selection only selects methods where the type * (not the value!) of the argument is "smaller" or the same as the parameter type. This is similar to how it's in * the Java language. That it only decides based on the parameter type is important because this way * {@link OverloadedMethodsSubset} can cache method lookup decisions using the types as the cache key. Problem is, * since you don't declare the exact numerical types in FTL, and FTL has only a single generic numeric type * anyway, what Java type a {@link TemplateNumberModel} uses internally is often seen as a technical detail of which * the template author can't always keep track of. So we investigate the value of the number too, * then coerce it down without overflow to a type that will match the most overloaded methods. (This * is especially important as FTL often stores numbers in {@link BigDecimal}-s, which will hardly ever match any * method parameters.) We could simply return that number, like {@code Byte(0)} for an {@code Integer(0)}, * however, then we would lose the information about what the original type was. The original type is sometimes * important, as in ambiguous situations the method where there's an exact type match should be selected (like, * when someone wants to select an overload explicitly with {@code m(x?int)}). Also, if an overload wins where * the parameter type at the position of the number is {@code Number} or {@code Object} (or {@code Comparable} * etc.), it's expected that we pass in the original value (an {@code Integer} in this example), especially if that * value is the return value of another Java method. That's why we use * {@link NumberWithFallbackType} numerical classes like {@link IntegerOrByte}, which represents both the original * type and the coerced type, all encoded into the class of the value, which is used as the overloaded method lookup * cache key. * *

See also: src\main\misc\overloadedNumberRules\prices.ods. * * @param num the number to coerce * @param typeFlags the type flags of the target parameter position; see {@link TypeFlags} * * @return The original number or a {@link NumberWithFallbackType}, depending on the actual value and the types * indicated in the {@code targetNumTypes} parameter. */ static Number addFallbackType(final Number num, final int typeFlags) { final Class numClass = num.getClass(); if (numClass == BigDecimal.class) { // For now we only support the backward-compatible mode that doesn't prevent roll overs and magnitude loss. // However, we push the overloaded selection to the right direction, so we will at least indicate if the // number has decimals.
