Methods

collapseToStart

  • collapseToStart(): Range

  • Create a new empty range using this range's start position.

    Returns Range

containsPosition

  • containsPosition(position: IPosition): boolean

  • Test if position is in this range. If the position is at the edges, will return true.

    Parameters

    Returns boolean

containsRange

  • containsRange(range: IRange): boolean

  • Test if range is in this range. If the range is equal to this range, will return true.

    Parameters

    Returns boolean

equalsRange

  • equalsRange(other: IRange | null): boolean

  • Test if this range equals other.

    Parameters

    Returns boolean

equalsSelection

  • Test if equals other selection.

    Parameters

    Returns boolean

getDirection

  • Get directions (LTR or RTL).

    Returns SelectionDirection

getEndPosition

  • Return the end position (which will be after or equal to the start position)

    Returns Position

getPosition

  • Get the position at positionLineNumber and positionColumn.

    Returns Position

getStartPosition

  • Return the start position (which will be before or equal to the end position)

    Returns Position

intersectRanges

  • A intersection of the two ranges.

    Parameters

    Returns Range | null

isEmpty

  • isEmpty(): boolean

  • Test if this range is empty.

    Returns boolean

plusRange

  • A reunion of the two ranges. The smallest position will be used as the start point, and the largest one as the end point.

    Parameters

    Returns Range

setEndPosition

  • setEndPosition(endLineNumber: number, endColumn: number): Selection

  • Create a new selection with a different positionLineNumber and positionColumn.

    Parameters

    • endLineNumber: number
    • endColumn: number

    Returns Selection

setStartPosition

  • setStartPosition(startLineNumber: number, startColumn: number): Selection

  • Create a new selection with a different selectionStartLineNumber and selectionStartColumn.

    Parameters

    • startLineNumber: number
    • startColumn: number

    Returns Selection

strictContainsRange

  • strictContainsRange(range: IRange): boolean

  • Test if range is strictly in this range. range must start after and end before this range for the result to be true.

    Parameters

    Returns boolean

toString

  • toString(): string

  • Transform to a human-readable representation.

    Returns string

Static areIntersecting

  • Test if the two ranges are intersecting. If the ranges are touching it returns true.

    Parameters

    Returns boolean

Static areIntersectingOrTouching

Static collapseToStart

  • Create a new empty range using this range's start position.

    Parameters

    Returns Range

Static compareRangesUsingEnds

  • A function that compares ranges, useful for sorting ranges It will first compare ranges on the endPosition and then on the startPosition

    Parameters

    Returns number

Static compareRangesUsingStarts

    Parameters

    Returns boolean

Static createWithDirection

  • createWithDirection(startLineNumber: number, startColumn: number, endLineNumber: number, endColumn: number, direction: SelectionDirection): Selection

  • Create with a direction.

    Parameters
