ParserState Class

public class ParserState : IParserState

public ParserState(ILLParser parser, ITokenReader tokenReader, IAstNodeBuilder astNodeBuilder, ITextSnapshot snapshot)

Parameter	Type	Description
parser	ILLParser	The ILLParser for which this state is tracking data.
tokenReader	ITokenReader	The ITokenReader that is used to read tokens during the parsing operation.
astNodeBuilder	IAstNodeBuilder	The IAstNodeBuilder to use for constructing AST node results
snapshot	ITextSnapshot	The ITextSnapshot used to initiate the parsing operation, if known.

public IAstNodeBuilder AstNodeBuilder { get; }

Property Value

IAstNodeBuilder:

The IAstNodeBuilder to use for constructing AST node results.

public object CustomData { get; set; }

Property Value

object:

Custom data that can be altered during a parsing operation.

public IEnumerable<IParseError> ParseErrors { get; }

Property Value

IEnumerable<IParseError>:

The collection of IParseError objects that will be returned in the IParseData parsing result.

public ILLParser Parser { get; }

Property Value

ILLParser:

The ILLParser for which this state is tracking data

public ITextSnapshot Snapshot { get; }

Property Value

ITextSnapshot:

The ITextSnapshot used to initiate the parsing operation, if known.

public ITokenReader TokenReader { get; }

Property Value

ITokenReader:

The ITokenReader that is used to read tokens during the parsing operation.

public IEnumerable<int> UntargetableParseErrorTokenIds { get; set; }

Property Value

IEnumerable<int>:

The collection of token IDs that should be avoided when determining where untargeted parse errors will appear.

Remarks

If a parse error is reported without a target token, the parser will normally place the parse error at the next token. If that token is one of the IDs found in this collection, the parse error will appear after the previous token instead. This property should be set to a collection of any IDs for visually-insignificant tokens that can be passed to the parser such as a line feed, line continuation, document end, etc.

public virtual void ReportError(IParseError parseError)

Parameter	Type	Description
