  • Constructor Details

    • InlineRun

      public InlineRun(InlineArea inline, int[] levels)
      Primary constructor.
      Parameters:
      inline - which generated this inline run
      levels - levels array

    • InlineRun

      public InlineRun(InlineArea inline, int level, int count)
      Alternate constructor.
      Parameters:
      inline - which generated this inline run
      level - for each index
      count - of indices

  • Method Details

    • getInline

      public InlineArea getInline()
      Obtain inline area that generated this inline run.
      Returns:
      inline area that generated this inline run.

    • getMinLevel

      public int getMinLevel()
      Obtain minimum bidi level for this run.
      Returns:
      minimum bidi level

    • getMaxLevel

      public int getMaxLevel()
      Obtain maximum bidi level for this run.
      Returns:
      maximum bidi level

    • isHomogenous

      public boolean isHomogenous()
      Determine if this run has homogenous (same valued) bidi levels.
      Returns:
      true if homogenous

    • split

      public List split()
      Split this inline run into homogenous runs.
      Returns:
      list of new runs

    • updateMinMax

      public void updateMinMax(int[] mm)
      Update a min/max array to correspond with this run's min/max values.
      Parameters:
      mm - reference to min/max array

    • maybeNeedsMirroring

      public boolean maybeNeedsMirroring()
      Determine if run needs mirroring.
      Returns:
      true if run is homogenous and (positive) odd (i.e., right to left)

    • reverse

      public void reverse()
      Reverse run (by incrementing reversal count, not actually reversing).

    • maybeReverseWord

      public void maybeReverseWord(boolean mirror)
      Reverse inline area if it is a word area and it requires reversal.
      Parameters:
      mirror - if true then also mirror characters

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object

    • toString

      public String toString()
      Overrides:
      toString in class Object
