Removed superfluous template parameter from interpreter

The Db parameter would actually have prevented different Context
overloads (or made more difficult than necessary).

Continued to implement standard serializing interpreters
...
Everything that is interpreted also has to move out of detail namespace,
because it might have to be specialized for a database connector
2014-01-11 21:51:57 +01:00
rbock
bef7cea6a6
Started to switch from member serialize -> non-member interpret
...
This will allow database connectors to specialize the interpretation of
the expression tree and interpret queries in vendor specific ways where
required.

Stripped a lot of superfluouos type information from result rows.
...
Moved member template into name class to utilize the fact the class
aliases are really just aliases.
This makes the code leaner in many cases and less complex for the compiler
(I guess). It also has the benefit, that the field name is available as
string in the result_rows. This might be useful for debugging one day.

Roland Bock
2defeff18e
Introduced field template to make result_row_t less specific.
...
It is sufficient to have name and type. There is no need for the result
"to know" what exact expression was used to define the column.
Surprisingly, template alias creates new templates (in contrast to
non-template using, which really just creates an alias of a type).
template<typename T> struct A{};
struct X
{
template<typename T>
using U = A<T>;
};
struct Y
{
template<typename T>
using U = A<T>;
template<>
using U<int> = X;
};
template<template<typename> class X>
struct Z{};
static_assert(std::is_same<X::U<int>, Y::U<int>>::value, "class aliases are really just aliases");
static_assert(not std::is_same<Z<X::U>, Z<Y::U>>::value, "template aliases are new templates");

is_null() throws for invalid rows

result_row objects can be constructed with raw result rows representing
