VBLexer Class
Represents a Visual Basic
lexer (lexical analyzer) implementation.
public class VBLexer : DotNetLexerBase, IMergableLexer, ILexer, IKeyedObject
- Inheritance:
- object MergableLexerBase DotNetLexerBase object
- Implements:
- IMergableLexer ILexer IKeyedObject
Constructors
VBLexer()
Initializes a new instance of the VBLexer
class.
public VBLexer()
Properties
LexicalStates
Gets the collection of lexical states used by this lexer.
public ILexicalStateCollection LexicalStates { get; }
Property Value
- ILexicalStateCollection:
The collection of lexical states used by this lexer.
Methods
GetAllLexicalStateTransitions()
Returns a collection containing all ILexicalStateTransition objects within the lexer.
public override IEnumerable<ILexicalStateTransition> GetAllLexicalStateTransitions()
Returns
- IEnumerable<ILexicalStateTransition>:
A collection containing all ILexicalStateTransition objects within the lexer.
Remarks
This method allows consumers to see which language transitions can be made within the lexer.
GetNextToken(ITextBufferReader, ILexicalState)
Performs a lex to return the next MergableLexerResult from a ITextBufferReader and seeks past it if there is a match.
public override MergableLexerResult GetNextToken(ITextBufferReader reader, ILexicalState lexicalState)
Parameter | Type | Description |
---|---|---|
reader | ITextBufferReader | An ITextBufferReader that is reading a text source. |
lexicalState | ILexicalState | The ILexicalState that specifies the current state. |
Returns
- MergableLexerResult:
A MergableLexerResult indicating a lexer result.
IsKeyword(string)
Returns whether the specified identifier is a keyword.
public bool IsKeyword(string identifier)
Parameter | Type | Description |
---|---|---|
identifier | string | The identifier text. |
Returns
- bool:
true
if the specified identifier is a keyword; otherwise,false
.
Remarks
This method doesn't return true
for contextual keywords.
