Each row of a SymScope table describes a scope, as follows:
| Offset | Size | Field | Description |
|---|---|---|---|
| 0 | 4 | Parent | Index of parent SymScope row, or -1 if scope has no parent. |
| 4 | 4 | StartOffset | CIL offset of the first byte in the scope. |
| 8 | 4 | EndOffset | CIL offset of the last byte in the scope. |
| 12 | 4 | HasChildren | 1 if scope has child scopes; 0 otherwise |
| 16 | 4 | HasVars | 1 if scope has variables; 0 otherwise |
The scopes belonging to a method must form a tree, with the following constraints:
-
A parent scope must precede its child scopes.
-
The StartOffset and EndOffset of a child scope must be within the (inclusive) range of offsets specified by its parent's scope.
