Class TextNodeComparator

java.lang.Object
org.outerj.daisy.diff.html.TextNodeComparator
All Implemented Interfaces:
Iterable<TextNode>, IRangeComparator
public class TextNodeComparator extends Object implements IRangeComparator, Iterable<TextNode>
A comparator that generates a DOM tree of sorts from handling SAX events. Then it can be used to compute the difference between DOM trees and mark elements accordingly.

    • TextNodeComparator

      public TextNodeComparator(DomTree tree, Locale locale)

  • Method Details

    • getBodyNode

      public BodyNode getBodyNode()

    • getRangeCount

      public int getRangeCount()
      Description copied from interface: IRangeComparator
      Returns the number of comparable entities.
      Specified by:
      getRangeCount in interface IRangeComparator
      Returns:
      the number of comparable entities

    • getTextNode

      public TextNode getTextNode(int i)

    • markAsNew

      public void markAsNew(int start, int end, ModificationType outputFormat)
      Marks the given range as new. In the output, the range will be formatted as specified by the anOutputFormat parameter.
      Parameters:
      start -
      end -
      outputFormat - specifies how this range shall be formatted in the output

    • markAsNew

      public void markAsNew(int start, int end)
      Marks the given range as new. In the output, the range will be formatted as "added".
      Parameters:
      start -
      end -

    • rangesEqual

      public boolean rangesEqual(int i1, IRangeComparator rangeComp, int i2)
      Description copied from interface: IRangeComparator
      Returns whether the comparable entity given by the first index matches an entity specified by the other IRangeComparator and index.
      Specified by:
      rangesEqual in interface IRangeComparator
      Parameters:
      i1 - the index of the comparable entity within this IRangeComparator
      rangeComp - the IRangeComparator to compare this with
      i2 - the index of the comparable entity within the other IRangeComparator
      Returns:
      true if the comparable entities are equal

    • skipRangeComparison

      public boolean skipRangeComparison(int arg0, int arg1, IRangeComparator arg2)
      Description copied from interface: IRangeComparator
      Returns whether a comparison should be skipped because it would be too costly (or lengthy).
      Specified by:
      skipRangeComparison in interface IRangeComparator
      Parameters:
      arg0 - a number on which to base the decision whether to return true or false
      arg1 - another number on which to base the decision whether to return true or false
      arg2 - the other IRangeComparator to compare with
      Returns:
      true to avoid a too lengthy range comparison

      public void handlePossibleChangedPart(int leftstart, int leftend, int rightstart, int rightend, TextNodeComparator leftComparator)

    • markAsDeleted

      public void markAsDeleted(int start, int end, TextNodeComparator oldComp, int before, int after, ModificationType outputFormat)
      Marks the given range as deleted. In the output, the range will be formatted as specified by the parameter anOutputFormat.
      Parameters:
      start -
      end -

      before -
      anOutputFormat - specifies how this range shall be formatted in the output

    • markAsDeleted

      public void markAsDeleted(int start, int end, TextNodeComparator oldComp, int before, int after)
