TdxSpreadSheetFunctionInfo.ParamInfo Field

Stores a reference (in Delphi) or pointer (in C++Builder) to the routine that defines the function syntax.

#Declaration

#Field Value

Type
TdxSpreadSheetFunctionParamInfo

#Remarks

The function signature is ready for use in formula expressions when it has both the implementation and syntax specification routines assigned to the Proc and ParamInfo fields, respectively.

A syntax specification routine defines the number of parameters, their types, and position order in a function call within a formula expression. Refer to the TdxSpreadSheetFunctionParamInfo procedural type description for details.

The TdxSpreadSheetFunctionsRepository.Add procedure uses the AParamInfo parameter value to initialize the ParamInfo field of a newly created function signature.

Note

The ToString function calls a syntax specification routine assigned to the ParamInfo to generate a syntax prototype string for the function signature.
