Class XpandIsDeleteLine

java.lang.Object
  org.eclipse.xtend.middleend.xtend.internal.xtendlib.XpandIsDeleteLine

public class XpandIsDeleteLine
extends java.lang.Object

This class supports the "isDeleteLine" feature of Xpand, i.e. the "-" at the end of a statement that deletes whitespace both backward and forward.
Since it is non-local functionality, it requires global postprocessing. For this purpose, a marker string is inserted wherever this deletion of whitespace should be performed.
Since this postprocessing requires transformation of the entire contents of a file into a flat string, this feature precludes streaming. Therefore a flag is introduced to indicate if the feature was actually used. This requires resetting at the beginning of each FILE statement.
