382 : set to CALCONLY, import filters have to insert a default value for this
383 : parameter, and export filters have to skip the parameter. If set to
384 : EXCELONLY, import filters have to skip the parameter, and export filters
385 : have to insert a default value for this parameter.
386 :
387 : The member mbValType specifies whether the parameter requires tokens to be
388 : of value type (VAL or ARR class).
389 :
390 : If set to false, the parameter is called to be REFTYPE. Tokens with REF
391 : default class can be inserted for the parameter (e.g. tAreaR tokens).
392 :
393 : If set to true, the parameter is called to be VALTYPE. Tokens with REF
394 : class need to be converted to VAL tokens first (e.g. tAreaR will be
395 : converted to tAreaV), and further conversion is done according to this
396 : new token class.
397 :
398 : The member meConv specifies how to convert the current token class of the
399 : token inserted for the parameter. If the token class is still REF this
400 : means that the token has default REF class and the parameter is REFTYPE
401 : (see member mbValType), the token will not be converted at all and remains
402 : in REF class. Otherwise, token class conversion is depending on the actual
403 : token class of the return value of the function containing this parameter.
404 : The function may return REF class (tFuncR, tFuncVarR, tFuncCER), or it may
405 : return VAL or ARR class (tFuncV, tFuncA, tFuncVarV, tFuncVarA, tFuncCEV,
406 : tFuncCEA). Even if the function is able to return REF class, it may return
407 : VAL or ARR class instead due to the VALTYPE data type of the parent
408 : function parameter that calls the own function. Example: The INDIRECT
409 : function returns REF class by default. But if called from a VALTYPE
410 : function parameter, e.g. in the formula =ABS(INDIRECT("A1")), it returns
411 : VAL or ARR class instead. Additionally, the repeating conversion types RPT
412 : and RPX rely on the conversion executed for the function token class.
413 :
414 : 1) ORG:
415 : Use the original class of the token (VAL or ARR), regardless of any
416 : conversion done for the function return class.
417 :
418 : 2) VAL:
419 : Convert ARR tokens to VAL class, regardless of any conversion done for
420 : the function return class.
421 :
422 : 3) ARR:
423 : Convert VAL tokens to ARR class, regardless of any conversion done for
424 : the function return class.
425 :
426 : 4) RPT:
427 : If the own function returns REF class (thus it is called from a REFTYPE
428 : parameter, see above), and the parent conversion type (for the function
429 : return class) was ORG, VAL, or ARR, ignore that conversion and always
430 : use VAL conversion for the own token instead. If the parent conversion
431 : type was RPT or RPX, repeat the conversion that would have been used if
432 : the function would return value type.
433 : If the own function returns value type (VAL or ARR class, see above),
434 : and the parent conversion type (for the function return class) was ORG,
435 : VAL, ARR, or RPT, repeat this conversion for the own token. If the
436 : parent conversion type was RPX, always use ORG conversion type for the
437 : own token instead.
438 :
439 : 5) RPX:
440 : This type of conversion only occurs in functions returning VAL class by
441 : default. If the own token is value type, and the VAL return class of
442 : the own function has been changed to ARR class (due to direct ARR
443 : conversion, or due to ARR conversion repeated by RPT or RPX), set the
444 : own token to ARR type. Otherwise use the original token type (VAL
445 : conversion from parent parameter will not be repeated at all). If
446 : nested functions have RPT or value-type RPX parameters, they will not
447 : repeat this conversion type, but will use ORG conversion instead (see
448 : description of RPT above).
449 :
450 : 6) RPO:
451 : This type of conversion is only used for the operands of all operators
452 : (unary and binary arithmetic operators, comparison operators, and range
453 : operators). It is not used for function parameters. On conversion, it
454 : will be replaced by the last conversion type that was not the RPO
455 : conversion. This leads to a slightly different behaviour than the RPT
456 : conversion for operands in conjunction with a parent RPX conversion.
