Position

scala.util.parsing.input.Position
trait Position

Position is the base trait for objects describing a position in a document.

It provides functionality for:

  • generating a visual representation of this position (longString);
  • comparing two positions (<).

To use this class for a concrete kind of document, implement the lineContents method.

Concrete methods

def <(that: Position): Boolean

Compare this position to another, by first comparing their line numbers, and then -- if necessary -- using the columns to break a tie.

Compare this position to another, by first comparing their line numbers, and then -- if necessary -- using the columns to break a tie.

Value parameters

`that`

a Position to compare to this Position

Attributes

Returns

true if this position's line number or (in case of equal line numbers) column is smaller than the corresponding components of that

override def equals(other: Any): Boolean

Compare this position to another, checking for equality.

Compare this position to another, checking for equality.

Value parameters

`that`

a Position to compare to this Position

Attributes

Returns

true if the line numbers and column numbers are equal.

Returns a more visual representation of this position. More precisely, the resulting string consists of two lines:

  1. the line in the document referred to by this position
  2. a caret indicating the column

Example:

  List(this, is, a, line, from, the, document)
               ^
