BuiltinIdentifiers function

Declaration

function BuiltinIdentifiers: TExprBuiltInManager

Function result

Returns global built-in identifiers manager

Description

The BuiltinIdentifiers function provides access to the global TExprBuiltInManager instance that contains all standard built-in functions and variables available to the expression parser. The manager is automatically initialized with default built-in functions when first accessed.

The returned manager includes predefined mathematical functions (sin, cos, sqrt, etc.), string manipulation functions (length, uppercase, etc.), date/time functions (now, date, etc.), and conversion functions between different data types.

This global manager can be extended with custom functions and variables, or individual parsers can use their own manager instances for specialized functionality.
