The returned string is empty() on success, non-empty() on + * mismatch. + * + * This function tests structure (types) rather than data values. It is + * intended for when a consumer expects an LLSD block with a particular + * structure, and must succinctly detect whether the arriving block is + * well-formed. For instance, a test of the form: + * @code + * if (! (data.has("request") && data.has("target") && data.has("modifier") ...)) + * @endcode + * could instead be expressed by initializing a prototype LLSD map with the + * required keys and writing: + * @code + * if (! llsd_matches(prototype, data).empty()) + * @endcode + * + * A non-empty return value is an error-message fragment intended to indicate + * to (English-speaking) developers where in the prototype structure the + * mismatch occurred. + * + * * If a slot in the prototype isUndefined(), then anything is valid at that + * place in the real object. (Passing prototype == LLSD() matches anything + * at all.) + * * An array in the prototype must match a data array at least that large. + * (Additional entries in the data array are ignored.) Every isDefined() + * entry in the prototype array must match the corresponding entry in the + * data array. + * * A map in the prototype must match a map in the data. Every key in the + * prototype map must match a corresponding key in the data map. (Additional + * keys in the data map are ignored.) Every isDefined() value in the + * prototype map must match the corresponding key's value in the data map. + * * Scalar values in the prototype are tested for @em type rather than value. + * For instance, a String in the prototype matches any String at all. In + * effect, storing an Integer at a particular place in the prototype asserts + * that the caller intends to apply asInteger() to the corresponding slot in + * the data. + * * A String in the prototype matches String, Boolean, Integer, Real, UUID, + * Date and URI, because asString() applied to any of these produces a + * meaningful result. + * * Similarly, a Boolean, Integer or Real in the prototype can match any of + * Boolean, Integer or Real in the data -- or even String. + * * UUID matches UUID or String. + * * Date matches Date or String. + * * URI matches URI or String. + * * Binary in the prototype matches only Binary in the data. + * + * @TODO: when a Boolean, Integer or Real in the prototype matches a String in + * the data, we should examine the String @em value to ensure it can be + * meaningfully converted to the requested type.
