java.lang.Object | +--org.eclipse.jface.text.CoordinatesTranslator
Implementation of IDocumentInformationMapping
matching ProjectionDocument
and
ProjectionDocumentManager
. The parent document is considered the original document, the projection
document is considered the image document.
This class is for internal use only.
Constructor Summary | |
CoordinatesTranslator(IDocument parent,
String parentCategory,
ProjectionDocument projection,
String projectionCategory)
Creates a new mapping between the given parent document and the given projection document. |
Method Summary | |
IRegion |
getCoverage()
Returns the minimal region of the original document that completely comprises all of the image document or null if there is no such region. |
int |
toClosestImageLine(int originLine)
Returns the line of the image document whose corresponding line in the original document is closest to the given line in the original document. |
int |
toImageLine(int originLine)
Returns the line of the image document that corresponds to the given line of the original document or -1 if there is no such line. |
int |
toImageOffset(int originOffset)
Returns the offset in the image document that corresponds to the given offset in the original document or -1 if there is no such offset |
IRegion |
toImageRegion(IRegion originRegion)
Returns the minimal region of the image document that completely comprises the given region of the original document or null if there is no such region. |
int |
toOriginLine(int imageLine)
