Provides the base requirements for an object that should receive parse output from a lexer.
public interface ILexerTargetProperties
HasInitialContext
Gets whether an initial context is available, from which incremental parsing can resume.
bool HasInitialContext { get; }Property Value
- Boolean:
trueif an initial context is available; otherwise,false.
Methods
OnPostParse(Int32)
Occurs after lexing ends.
void OnPostParse(int endOffset)| Parameter | Type | Description |
|---|---|---|
| endOffset | Int32 | The offset at which parsing has stopped. |
OnPreParse(ref Int32)
Occurs before lexing starts.
ILexerContext OnPreParse(ref int startOffset)| Parameter | Type | Description |
|---|---|---|
| startOffset | Int32 | The offset at which parsing will commence. |
Returns
- ILexerContext:
A ILexerContext that contains information about the starting context.
OnTokenParsed(IToken, ILexicalScopeStateNode)
Occurs when an IToken is parsed by the lexer.
bool OnTokenParsed(IToken newToken, ILexicalScopeStateNode scopeStateNode)| Parameter | Type | Description |
|---|---|---|
| newToken | IToken | The IToken that was parsed. |
| scopeStateNode | ILexicalScopeStateNode | The ILexicalScopeStateNode at the start of the token. |
Returns
- Boolean:
trueif the lexing should continue; otherwise,false.
