public final class SourceCompactor extends java.lang.Object implements CharStreamSource
Use one of the following methods to obtain the output:
The output text is functionally equivalent to the original source and should be rendered identically.
Compacting an entire Source object performs a full sequential parse automatically.

CharStreamSource-1 if no estimate is available.
The returned value should be used as a guide for efficiency purposes only, for example to set an initial StringBuilder capacity.
There is no guarantee that the length of the output is indeed less than this value,
as classes implementing this method often use assumptions based on typical usage to calculate the estimate.
Although implementations of this method should never return a value less than -1, users of this method must not assume that this will always be the case. Standard practice is to interpret any negative value as meaning that no estimate is available.

The default is to use the same new line string as is used in the source document, which is determined via the Source.getNewLine() method.
If the source document does not contain any new lines, a "best guess" is made by either taking the new line string of a previously parsed document,
or using the value from the static Config.NewLine property.
Specifying a null argument resets the property to its default value, which is to use the same new line string as is used in the source document.
