Class IndentationContext

  • public class IndentationContext
extends java.lang.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.

      • IndentationContext

        public IndentationContext()
        Creates a new IndentationContext with empty indentation.

      • IndentationContext

        public IndentationContext​(java.util.List<TextElement> initialIndentation)
        Creates a new IndentationContext with the specified initial indentation. The provided list is copied to prevent external modifications.
        Parameters:
        initialIndentation - the initial indentation elements (will be copied)

    • Method Detail

      • increase

        public void increase()
        Increases indentation by one level. Adds STANDARD_INDENTATION_SIZE space characters to the current indentation.

      • decrease

        public void decrease()
        Decreases indentation by one level. Removes up to STANDARD_INDENTATION_SIZE characters from the end of the current indentation. Does nothing if the current indentation has fewer elements than STANDARD_INDENTATION_SIZE.

      • getCurrent

        public java.util.List<TextElement> getCurrent()
        Returns a copy of the current indentation elements. The returned list is unmodifiable to prevent accidental modifications.
        Returns:
        unmodifiable view of current indentation elements

      • size

        public int size()
        Returns the number of indentation characters currently stored.
        Returns:
        count of indentation elements

      • clear

        public void clear()
        Clears all indentation, resetting to zero indentation.

      • set

        public void set​(java.util.List<TextElement> newIndentation)
        Replaces the current indentation with the specified elements. The provided list is copied to prevent external modifications.
