Description

TParser allows DFM files to be parsed.

The TParser is principally used internally in RAD Studio to parse (tokenise) VCL Form files (which have a .dfm extension on Win32). However, it can potentially be used as a more general parser.

A VCL form file contains the description of the properties of the form and the components it owns. Each form file represents a single form, which usually corresponds to a window or dialog box in an application.

The parsing dissects the form text into a set of symbol strings, and value strings. Values may be string representations of strings, widestrings, integers, or floating point numbers.

Navigation is performed by repeatedly using the NextToken method to retrieve a sequence of tokens (symobols and values). The value of each retrieved token is obtained using the TParser methods :

Method	Returns	Token(s)
TokenFloat	Float	toFloat
TokenInt	Integer	toInteger
TokenString	String	toFloat, toInteger, toString, toSymbol
TokenWideString	WideString	toWString

toEOF is the token returned when the form navigation is complete.
