Constructor Detail

SimpleVStreamTexter

public SimpleVStreamTexter(SpanMaker spanMaker,
                           Enfilade1D.Maker enfMaker,
                           EnfiladeAligner enfAligner)

Deprecated. EnfiladeAligner should not be provided by Space: it's too complicated and ill-defined for that.

Create a new object with given new span maker.

Parameters:

spanMaker - In order to perform setText() and insertText(), this object needs to create new spans. The spanMaker interface allows us to polymorphize that.

SimpleVStreamTexter

public SimpleVStreamTexter(SpanMaker spanMaker,
                           Enfilade1D.Maker enfMaker)

Create a new object with given new span maker.

Parameters:

spanMaker - In order to perform setText() and insertText(), this object needs to create new spans. The spanMaker interface allows us to polymorphize that.

Method Detail

setSpace

public void setSpace(ModularSpace space)

Description copied from interface: ModularCellTexter

Set the modularspace that this celltexter is part of.

Specified by:

setSpace in interface ModularCellTexter

getFromMap

protected Enfilade1D getFromMap(Cell c)

The innermost routine that uses the actual map. For keeping change lists etc, override this and setMap.

setMap

protected void setMap(Cell c,
                      Enfilade1D enf)

The innermost routine that uses the actual map. For keeping change lists etc, override this and getFromMap.

getCellsWithContent

public java.util.Set getCellsWithContent()

The innermost routine that uses the actual map. For keeping change lists etc, override this and set/getFromMap.

Specified by:

getCellsWithContent in interface CellTexter
