Members
| Member name | Description | |
|---|---|---|
| Autos | 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). | |
| Check | Parse the entire source file, checking for errors. This pass should also create lists of matching language pairs, triplets, members, and methods. | |
| CodeSpan | Parse the section of code containing the specified ___location to find the extent of the statement. Used in validating breakpoints. | |
| CompleteWord | Parse to get the partially completed word before the current position in order to show a list of possible completions (members, arguments, methods). | |
| DisplayMemberList | Parse the separator and the possible name before it, to obtain a list of members to be shown in a member completion list. | |
| Goto | 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. | |
| HighlightBraces | 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. | |
| MatchBraces | Parse the language pair at the given ___location to finds its match. | |
| MemberSelect | Parse the separator character before the current ___location to obtain a list of members for the class. | |
| MemberSelectAndHighlightBraces | 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). | |
| MethodTip | Parse the method name before the current position to produce a list of all overloaded method signatures that match the method name. | |
| None | A placeholder value indicating that no parsing should be done. | |
| QuickInfo | Parse the identifier or selection at the given ___location to obtain type information to be shown in an IntelliSense quick info tool tip. |
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.
