com.github.javaparser.printer.lexicalpreservation.IndentationContext
public class IndentationContext extends Object
Maintains the current indentation state during lexical preservation operations. This class encapsulates a mutable list of indentation elements (spaces/tabs) that represents the current indentation level. It provides methods to increase/decrease indentation and query the current state. Instances of this class are typically created at the start of a difference application and maintained throughout the process.
