Detailed Description
Private header for the SABNF parser.
The declarations here are used internally by the parser. Some of the APG utilities and helper objects will use this "inside" information but the user should rarely need this header for an application.

◆ bGetParserInitData()
| abool bGetParserInitData | ( | parser_init * | spParserInit, |
| luint * | luipParserInit | ||
| ) |
Re-size the initialization data to the required integer size.
Definition at line 80 of file parser-get-init.c.
◆ ucGetMapVal()
◆ uiGetAcharTable()
| aint uiGetAcharTable | ( | parser_init * | spParserInit, |
| achar * | acpAcharTable | ||
| ) |
Extract the alphabet character table from the initialization data.
Definition at line 43 of file parser-get-init.c.
◆ vGetChildListTable()
Extract the child index list from the initialization data.
Definition at line 130 of file parser-get-init.c.
◆ vpParserAllocCtor()
The parser constructor.
The generator can generate the parser's initialization data in one of two ways.
- With vApiOutput() the data is in an C-language code file, "namespace.c". When constructing a parser from the file data, no further memory allocations for it are necessary.
- With vpApiOutputParser() the data is in the API object's context and must be copied to the parser's context to separate it completely from the API. That is, the parser's context must remain complete and valid even if the API context is destroyed. This function has a switch to chose between the two.
- Parameters
-
spException Pointer to a valid exception structure initialized with vExCtor() or XCTOR(). If not valid, the application will silently exit with a BAD_CONTEXT exit code. vpParserInit Pointer to the initialization data. bAllocateTables If true, memory is allocated to copy the initialization data into the parser'scontext. If false, no memory allocation and copying is done.
- Returns
- Pointer to a parser context. Exceptions thrown on errors.
◆ vTranslateOpcodes()
