Macro Definition Documentation

◆ CLOUDVIEWER_CONCAT

#define CLOUDVIEWER_CONCAT	(	s1,
		s2
	)	CLOUDVIEWER_CONCAT_IMPL_(s1, s2)

Definition at line 26 of file Preprocessor.h.

◆ CLOUDVIEWER_CONCAT_IMPL_

#define CLOUDVIEWER_CONCAT_IMPL_	(	s1,
		s2
	)	s1##s2

CLOUDVIEWER_CONCAT(s1, s2)

Concatenates the expanded expressions s1 and s2.

Definition at line 25 of file Preprocessor.h.

◆ CLOUDVIEWER_FIX_MSVC_

#define CLOUDVIEWER_FIX_MSVC_ ( ... ) __VA_ARGS__

CLOUDVIEWER_FIX_MSVC_(...)

Internal helper function which defers the evaluation of the enclosed expression.

Use this macro only to workaround non-compliant behaviour of the MSVC preprocessor.

Note: Could be dropped in the future if the compile flag /Zc:preprocessor can be applied.

Definition at line 20 of file Preprocessor.h.

◆ CLOUDVIEWER_GET_NTH_ARG_

#define CLOUDVIEWER_GET_NTH_ARG_ ( ... ) CLOUDVIEWER_FIX_MSVC_(CLOUDVIEWER_GET_NTH_ARG_IMPL_(__VA_ARGS__))

CLOUDVIEWER_NUM_ARGS(...)

Returns the number of supplied arguments.

Note: Only works for 1-10 arguments.

Definition at line 39 of file Preprocessor.h.

◆ CLOUDVIEWER_GET_NTH_ARG_IMPL_

#define CLOUDVIEWER_GET_NTH_ARG_IMPL_	(	arg1,
		arg2,
		arg3,
		arg4,
		arg5,
		arg6,
		arg7,
		arg8,
		arg9,
		arg10,
		N,
		...
	)	N

◆ CLOUDVIEWER_NUM_ARGS

#define CLOUDVIEWER_NUM_ARGS ( ... ) CLOUDVIEWER_GET_NTH_ARG_(__VA_ARGS__, CLOUDVIEWER_REVERSE_NUM_SEQUENCE_())

Definition at line 45 of file Preprocessor.h.

◆ CLOUDVIEWER_OVERLOAD

#define CLOUDVIEWER_OVERLOAD	(	func,
		...
	)	CLOUDVIEWER_CONCAT(func, CLOUDVIEWER_NUM_ARGS(__VA_ARGS__))

CLOUDVIEWER_OVERLOAD(func, ...)

Overloads the enumerated macros func1, func2, etc. based on the number of additional arguments.

Example:

#define FOO_1(x1) foo(x1)
#define FOO_2(x1, x2) bar(x1, x2)
#define FOO(...) '\'
    CLOUDVIEWER_FIX_MSVC_(CLOUDVIEWER_OVERLOAD(FOO_,
    __VA_ARGS__)(__VA_ARGS__))
 
FOO(1)    -> foo(1)
FOO(2, 3) -> bar(2, 3)

Definition at line 65 of file Preprocessor.h.

◆ CLOUDVIEWER_REVERSE_NUM_SEQUENCE_

#define CLOUDVIEWER_REVERSE_NUM_SEQUENCE_ ( ) 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0

Definition at line 44 of file Preprocessor.h.

◆ CLOUDVIEWER_STRINGIFY

#define CLOUDVIEWER_STRINGIFY ( s ) CLOUDVIEWER_STRINGIFY_IMPL_(s)

Definition at line 32 of file Preprocessor.h.

◆ CLOUDVIEWER_STRINGIFY_IMPL_

#define CLOUDVIEWER_STRINGIFY_IMPL_ ( s ) #s

CLOUDVIEWER_STRINGIFY(s)

Converts the expanded expression s to a string.

Definition at line 31 of file Preprocessor.h.
