struct CrlAnyValue / crl_any_value_t

Concrete Class

Description

A factory for Values just like AnyUserData for UserData. This class enables on-the-fly conversion from many types to Value *.

Note

We could make this CRL_REF() and CRL_UNREF() the value automatically, but this function is meant to be a converter only, so we don't do that to keep the code small.

Detailed Descriptions

CrlValue * value

C++:	CrlValue * CrlAnyValue::value
C:	Not available.

[constructor] CrlAnyValue (char const *)

C++:	CrlAnyValue::CrlAnyValue (char const *)
C:	Not available.

This invokes string2symbol() and then creates a ValueSymbol.

[constructor] CrlAnyValue (unsigned_t)

C++:	CrlAnyValue::CrlAnyValue (crl_unsigned_t)
C:	Not available.

This generates unsigned values (ValueUnsigned).

For any other numeric type, use the proper constructor (e.g. for ValueSigned, ValueFloat, ValueRange, etc.). If we provided more numerical type constructors, we would get ambiguous overloads and too much automatism in general leading to bugs you would not see easily, so the only integer typed constructor is this one.

[constructor] CrlAnyValue (Item *)

C++:	CrlAnyValue::CrlAnyValue (CrlItem *)
C:	Not available.

This makes a ValueItem.

#if defined(CRL_VALUE_TO_ANY_VALUE)

[constructor] CrlAnyValue (Value * x)

C++:	CrlAnyValue::CrlAnyValue (CrlValue * x)
C:	Not available.

This would make it feasible to let all functions that take a Value use AnyValue instead for their parameters. However, since such functions are not callable from C, all functions accepting Values have both types of functions anyway.

Also, broken C++ compilers might get ambiguous overloads.

#endif

operator CrlValue * () const

C++:	CrlAnyValue::operator CrlValue * () const
C:	Not available.

Automatically casts back to Value *.
