Fields
| Name | Value | Description |
|---|---|---|
| None | 0 | A placeholder value indicating that no parsing should be done. |
| MemberSelect | 1 | Parse the separator character before the current ___location to obtain a list of members for the class. |
| HighlightBraces | 2 | Parse to find the matching language pairs (such as "{" and "}" or "<" and ">") that enclose the given ___location so they and their contents can be highlighted. |
| MemberSelectAndHighlightBraces | 3 | Parse the character at the current ___location to complete a member selection and to highlight the matching pair to the parsed character (such as a ")" after a method name). |
| MatchBraces | 4 | Parse the language pair at the given ___location to finds its match. |
| Check | 5 | Parse the entire source file, checking for errors. This pass should also create lists of matching language pairs, triplets, members, and methods. |
| CompleteWord | 6 | Parse to get the partially completed word before the current position in order to show a list of possible completions (members, arguments, methods). |
| DisplayMemberList | 7 | Parse the separator and the possible name before it, to obtain a list of members to be shown in a member completion list. |
| QuickInfo | 8 | Parse the identifier or selection at the given ___location to obtain type information to be shown in an IntelliSense quick info tool tip. |
| MethodTip | 9 | Parse the method name before the current position to produce a list of all overloaded method signatures that match the method name. |
| Autos | 10 | Parse the code block at the given ___location to obtain any expressions that might be of interest in the Autos debugging window (an expression is the name of variable or parameter that can be evaluated to produce a value). |
| CodeSpan | 11 | Parse the section of code containing the specified ___location to find the extent of the statement. Used in validating breakpoints. |
| Goto | 12 | Parse the identifier or expression at the specified ___location to obtain a possible URI of a file where the identifier is defined, declared, or referenced. |
Remarks
These are all the reasons a parsing operation is performed in a language service. Most reasons confine parsing to the current line and therefore are very fast, some reasons call for a more extensive parsing that can take a while and are therefore typically done on a background thread.
