class SemanticParser

Defined at line 92 of file ../../src/lib/fidl_codec/semantic_parser.h

Parser for the language which defines semantic rules for FIDL methods.

Public Methods

void NextLexicalToken ()

Reduce the next lexical token. The parser always has a current not used yet lexical token

reduced by NextLexicalToken.

void SemanticParser (LibraryLoader * library_loader, std::string_view buffer, ParserErrors * errors)

Location GetLocation ()

Returns the location of the current lexical token.

Defined at line 101 of file ../../src/lib/fidl_codec/semantic_parser.h

std::ostream & AddError ()

Adds an error at the current lexical token location.

Defined at line 104 of file ../../src/lib/fidl_codec/semantic_parser.h

Skips text until a semicolon or a right brace are found. If a semicolon is found, the parsing

continues after the semicolon. If a right brace is found, the parsing continues before the

void SkipBlock ()

Skips text until a semicolon or a right brace are found. The parsing continue after the

semicolon or the right brace. If an embeded block is found (delimited by left and right

braces), the block is skipped.

generated.

Defined at line 173 of file ../../src/lib/fidl_codec/semantic_parser.h

void SkipRightBrace ()

Skips text until a right brace is found. The parsing continue after the right brace. If an

embeded block is found (delimited by left and right braces), the block is skipped.
