ParserContext Description sealed class Tinman.Core.Parsing.ParserContext Derived from Disposable abstract Represents the context while parsing the content of a ICodeInput object. Public / Methods Begin public method Begin → (1) right opt : bool = false Calling from the ast-if-right rule? Begins a new parser context frame. BeginNoAst public method BeginNoAst → () Begins a new parser context frame (no AST modification). Commit public method Commit → () Commits the current parser context frame. CommitNoAst public method CommitNoAst → () Commits the current parser context frame (no AST modification). Consume public method Consume → (1) n opt : int32 = 1 Number of input tokens to consume. Consumes the next n opt input tokens and advances the position accordingly. CreateAst public method CreateAst → (1) rule in : IGrammarRule The enclosing grammar rule. returns → AstNode The created AstNode object. Creates an AstNode object from the current parser content. GetParserErrors public method GetParserErrors → () returns → ValidateResult The parser errors. Returns the collected parser errors. Peek public method Peek → (1) offset opt : int32 = 0 The relative offset. returns → char The token or '\0' for out-of-range offsets. Peeks a token relative to the current position without modifying the current position. If the resulting token offset lies outside the valid range, the default value of the token type will be returned. Reset public method Reset → (2) grammar opt : Grammar = null The grammar to use or null. input opt : ICodeInput = null The code input to consume or null. returns → ParserContext this Resets the parser context. Rollback public method Rollback → () Rolls back the current parser context frame. RollbackNoAst public method RollbackNoAst → () Rolls back the current parser context frame (no AST modification). RulePositionStack public method RulePositionStack → (1) rule in : IRule The rule object. returns → ParserContextStack The position stack. Returns the position stack for the given rule. Skip public method Skip → () returns → bool true if at least one input character has been skipped, false if not. Skips subsequent input according to the skip rule of the current grammar of the top-most grammar rule. Public / Attributes IsEof public attribute IsEof → (get) value : bool true if there are no more input tokens following the current position, false if at least one more token will follow. Has the end of the input token sequence been reached? Position public attribute Position → (get) value : int32 [>=0] The current position. Returns the current position. Remaining public attribute Remaining → (get) value : int32 [>=0] The number of remaining input tokens. Returns the number of remaining input tokens. ParseResult ParserContextStack
