Class AbstractLangiumParserAbstract

Current state of the unordered groups

Executes a grammar action that modifies the currently active AST node

Performs alternatives parsing (the | operation in EBNF/Langium)

Parses the callback 1 or more times (the + operation in EBNF/Langium)

Finishes construction of the current AST node. Only used by the AST parser.

Consumes a specific token type from the token input stream. Requires a unique index within the rule for a specific token type.

Returns the executable rule function for the specified rule name

The rule stack indicates the indices of rules that are currently invoked, in order of their invocation.

Whether the parser is currently actually in use or in "recording mode". Recording mode is activated once when the parser is analyzing itself. During this phase, no input exists and therefore no AST should be constructed

Parses the callback 0 or more times (the * operation in EBNF/Langium)

Parses the callback as optional (the ? operation in EBNF/Langium)

Adds a new parser rule to the parser

Invokes the executable function for a given parser rule. Requires a unique index within the rule for a specific sub rule. Arguments can be supplied to the rule invocation for semantic predicates
