public BidiOrder(byte[] types)
types
- the types array
public BidiOrder(byte[] types, byte paragraphEmbeddingLevel)
types
- the types array
paragraphEmbeddingLevel
- the externally supplied paragraph embedding level.

public static final byte getDirection(char c)
public byte[] getLevels()
public byte[] getLevels(int[] linebreaks)
The returned levels array contains the resolved level for each bidi code passed to the constructor.
The linebreaks array must include at least one value. The values must be in strictly increasing order (no duplicates) between 1 and the length of the text, inclusive. The last value must be the length of the text.
linebreaks
- the offsets at which to break the paragraph
public int[] getReordering(int[] linebreaks)
The reordering array maps from a visual index to a logical index. Lines are concatenated from left to right. So for example, the fifth character from the left on the third line is
getReordering(linebreaks)[linebreaks[1] + 4](linebreaks[1] is the position after the last character of the second line, which is also the index of the first character on the third line, and adding four gets the fifth character from the left).
The linebreaks array must include at least one value. The values must be in strictly increasing order (no duplicates) between 1 and the length of the text, inclusive. The last value must be the length of the text.
linebreaks
- the offsets at which to break the paragraph.
