    interface IScriptSnapshot {
        dispose?(): void;
        getChangeRange(oldSnapshot: IScriptSnapshot): TextChangeRange | undefined;
        getLength(): number;
        getText(start: number, end: number): string;
    }
    Index

    Methods

    dispose? getChangeRange getLength getText

    Methods

    • Releases all resources held by this script snapshot

      Returns void

    • Gets the TextChangeRange that describe how the text changed between this text and an older version. This information is used by the incremental parser to determine what sections of the script need to be re-parsed. 'undefined' can be returned if the change range cannot be determined. However, in that case, incremental parsing will not happen and the entire document will be re - parsed.

      Parameters

      Returns TextChangeRange | undefined

    • Gets the length of this script snapshot.

      Returns number

    • Gets a portion of the script snapshot specified by [start, end).

      Parameters

      • start: number
      • end: number

      Returns string
