Class orion.textview.Ruler
This interface represents a ruler for the text view.
A Ruler is a graphical element that is placed either on the left or on the right side of the view. It can be used to provide the view with per line decoration such as line numbering, bookmarks, breakpoints, folding disclosures, etc.
There are two types of rulers: page and document. A page ruler only shows the content for the lines that are visible, while a document ruler always shows the whole content.

- See:
- #setAnnotationModel
{orion.textview.Annotation[]}
getAnnotations(startLine, endLine)
Returns the annotations for a given line range merging multiple
annotations when necessary.
This method is called by the text view when the ruler is redrawn.
- Parameters:
- {Number} startLine
- the start line index
- {Number} endLine
- the end line index
- Returns:
- {orion.textview.Annotation[]} the annotations for the line range. The array might be sparse.
{orion.textview.Annotation[]}
getAnnotationsByType(annotationModel, start, end)
Returns an array of annotations in the specified annotation model for the given range of text sorted by type.
Defined in: </shared/eclipse/e4/orion/I201301232230/plugins/org.eclipse.orion.client.editor/web/orion/textview/annotations.js>.
Defined in: </shared/eclipse/e4/orion/I201301232230/plugins/org.eclipse.orion.client.editor/web/orion/textview/annotations.js>.
- Parameters:
- {orion.textview.AnnotationModel} annotationModel
- the annotation model.
- {Number} start
- the start offset of the range.
- {Number} end
- the end offset of the range.
- Returns:
- {orion.textview.Annotation[]} an annotation array.
getAnnotationTypePriority(type)
Gets the annotation type priority. The priority is determined by the
order the annotation type is added to the receiver. Annotation types
added first have higher priority.
Defined in: </shared/eclipse/e4/orion/I201301232230/plugins/org.eclipse.orion.client.editor/web/orion/textview/annotations.js>.
Returns 0 if the annotation type is not added.

- Parameters:
- {Object} type
- the annotation type
{String}
getLocation()
Returns the ruler location.
- Returns:
- {String} the ruler location, which is either "left" or "right".
- See:
- #getOverview
{String}
