Boolean and test operators

Operators that give a boolean value.

Every program can use these operators. No import is necessary.

Target support marks

• ✔Own template
• ✱Default template
• ✕No template

The operator works for a target with an own template and for a target with the default template. The default template is the * entry of the definition: it writes the same code for every target that has no template of its own. A target with no template writes no code, and a program that uses the operator does not compile for that target.

!null?

(!null? arg) → boolean

!null?(arg: <optional>boolean)

!null?

(!null? arg) → boolean

!null?(arg: <optional>buffer)

buffer is a value type (std::vector<uint8_t>) in C++; the generic `!= NULL` path below does not compile. Present == non-empty, matching the string overload above.

null?

(null? arg) → boolean

null?(arg: <optional>boolean)

an optional boolean is a plain `bool` on C++ (there is no place to put "absent"), so the generic `== NULL` path compares a bool against a null pointer constant -- g++ warns `NULL used in arithmetic`. false is the absent value, which is what getBoolean already answers for a missing key.

null?

(null? arg) → boolean

null?(arg: <optional>buffer)

buffer is a value type (std::vector<uint8_t>) in C++, so the generic `!= NULL` path below does not compile. Treat empty/absent as null, mirroring the string overload above.

unwrap

(unwrap arg) → boolean

unwrap(arg: <optional>boolean)

`bool?` is a Nullable<bool> like the two above, and `if (unwrap ok)` without the .Value does not compile. Only C# has an entry, so every other target keeps reaching the generic overload below.
