_detail_ARMARX_IF_IN_PARENTHESIS_EXPAND

#define _detail_ARMARX_IF_IN_PARENTHESIS_EXPAND

(

#include <ArmarXCore/util/CPPUtility/Preprocessor/if_in_parentheses.h>

Value:

,

If the first parameter is in parenthesis, the second parameter is returned, otherwise the third is returned.

Definition at line 32 of file if_in_parentheses.h.

ARMARX_ANONYMOUS_VARIABLE

#define ARMARX_ANONYMOUS_VARIABLE   ARMARX_ANONYMOUS_VARIABLE_WITH_PREFIX(armarxAnonymousVariable)

#include <ArmarXCore/util/CPPUtility/Preprocessor/anonymous_variable.h>

creates a identifier.

The created identifier contains the linenumber and is unique per translation unit. This makro's usecase are other macros, where a variable for RAII has to be created in the enclosing scope.

can be used like this:

void foo()
{
    std::mutex mtx;
    std::lock_guard<std::mutex> ARMARX_ANONYMOUS_VARIABLE(mtx);
    //guarded section
}

ARMARX_ANONYMOUS_VARIABLE_WITH_PREFIX

#define ARMARX_ANONYMOUS_VARIABLE_WITH_PREFIX

(

pre

)

#include <ArmarXCore/util/CPPUtility/Preprocessor/anonymous_variable.h>

Value:

    ARMARX_CONCATENATE_5(pre, _IN_LINE_, __LINE__, _WITH_COUNT_, __COUNTER__)

creates a identifier with a given prefix.

The prefix may help when the variable shows up in compiler output.

can be used like this:

void foo()
{
    std::mutex mtx;
    std::lock_guard<std::mutex> ARMARX_ANONYMOUS_VARIABLE_WITH_PREFIX(guard)(mtx);
    //guarded section
}
