This object is used in various places to indicate a region within the editor. To better visualize how this works, imagine a rectangle. Each quadrant of the rectangle is analogus to a range, as ranges contain a starting row and starting column, and an ending row, and ending column.

- Range.new(Number startRow, Number startColumn, Number endRow, Number endColumn)

Creates a new Range object with the given starting and ending row and column points.

Arguments

startRow	Number	Required. The starting row
startColumn	Number	Required. The starting column
endRow	Number	Required. The ending row
endColumn	Number	Required. The ending column

- Range.clipRows(Number firstRow, Number lastRow)

lastRow	Number	Required. The ending row

- Range.clone()
- - Range

Returns a duplicate of the calling range.

- Range.collapseRows()
- - Range

Returns a range containing the starting and ending rows of the original range, but with a column value of 0.

- Range.compare(Number row, Number column)
- - Number

Checks the row and column points with the row and column points of the calling range.

Arguments

row	Number	Required. A row point to compare with
column	Number	Required. A column point to compare with

- Range.compareEnd(Number row, Number column)

Checks the row and column points with the row and column points of the calling range.

Arguments

row	Number	Required. A row point to compare with
column	Number	Required. A column point to compare with

Compares this range (A) with another range (B).

Arguments

range	Range	Required. A range to compare with

column	Number	Required. A column point to compare with

- Range.contains(Number row, Number column)
- - Boolean
- Related to Range.compare

Returns true if the row and column provided are within the given range. This can better be expressed as returning true if:

this.start.row <= row <= this.end.row && this.start.column <= column <= this.end.column

Arguments

column	Number	Required. A column to check for

- Range.containsRange(Range range)
- - Boolean
- Related to Range.comparePoint

Checks the start and end points of range and compares them to the calling range. Returns true if the range is contained within the caller's range.

Arguments

range	Range	Required. A range to compare with

- Range.extend(Number row, Number column)
- - Range

Changes the row and column points for the calling range for both the starting and ending points. This method returns that range with a new row.

Arguments

row	Number	Required. A new row to extend to
column	Number	Required. A new column to extend to

- Range.fromPoints(Range start, Range end)
- - Range

Creates and returns a new Range based on the row and column of the given parameters.

Arguments

start	Range	Required. A starting point to use
end	Range	Required. An ending point to use

- Range.inside(Number row, Number column)
- - Boolean
- Related to Range.compare

Returns true if the row and column are within the given range.

Arguments

row	Number	Required. A row point to compare with
column	Number	Required. A column point to compare with

- Range.insideEnd(Number row, Number column)
- - Boolean
- Related to Range.compare

Returns true if the row and column are within the given range's ending points.

Arguments

row	Number	Required. A row point to compare with
column	Number	Required. A column point to compare with

- Range.insideStart(Number row, Number column)
- - Boolean
- Related to Range.compare

Returns true if the row and column are within the given range's starting points.

Arguments

row	Number	Required. A row point to compare with
column	Number	Required. A column point to compare with

- Range.intersects(Range range)
- - Boolean

Returns true if passed in range intersects with the one calling this method.

Arguments

range	Range	Required. A range to compare with

- Range.isEnd(Number row, Number column)
- - Boolean

Returns true if the caller's ending row point is the same as row, and if the caller's ending column is the same as column.

Arguments

row	Number	Required. A row point to compare with
column	Number	Required. A column point to compare with

- Range.isEqual(Range range)
- - Boolean

Returns true if and only if the starting row and column, and ending tow and column, are equivalent to those given by range.

Arguments

range	Range	Required. A range to check against

- Range.isMultiLine()
- - Boolean

Returns true if the range spans across multiple lines.

- Range.isStart(Number row, Number column)
- - Boolean

Returns true if the caller's starting row point is the same as row, and if the caller's starting column is the same as column.

Arguments

row	Number	Required. A row point to compare with
column	Number	Required. A column point to compare with
