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.

the location for the ruler.
{String} rulerOverview Optional, Default: "page"
the overview for the ruler.

Method Detail
addAnnotationType(type)
Adds an annotation type to the receiver.

Only annotations of the specified types will be shown by the receiver.


Defined in: </shared/eclipse/e4/orion/I201301232230/plugins/org.eclipse.orion.client.editor/web/orion/textview/annotations.js>.
Parameters:
{Object} type
the annotation type to be shown
See:
#removeAnnotationType
#isAnnotationTypeVisible

{orion.textview.AnnotationModel} getAnnotationModel()
Returns the annotation model.
Returns:
{orion.textview.AnnotationModel} the ruler annotation model.
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>.
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.

Returns 0 if the annotation type is not added.


Defined in: </shared/eclipse/e4/orion/I201301232230/plugins/org.eclipse.orion.client.editor/web/orion/textview/annotations.js>.
Parameters:
{Object} type
the annotation type
See:
#addAnnotationType
#removeAnnotationType
#isAnnotationTypeVisible

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

{String} getOverview()
Returns the ruler overview type.
Returns:
{String} the overview type, which is either "page" or "document".

Returns the text view.
Returns:
{orion.textview.TextView} the text view.

Parameters:
{orion.textview.Annotation} annotation
the annotation overlay for lines with multiple annotations.
See:
#setMultiAnnotation

setView(view)
Sets the view for the ruler.
