public BidiOrder(char[] text, int offset, int length, sbyte paragraphEmbeddingLevel)

Parameters

text char[]

offset int

length int

paragraphEmbeddingLevel sbyte

BidiOrder(sbyte[])

Initialize using an array of direction types. Types range from TYPE_MIN to TYPE_MAX inclusive and represent the direction codes of the characters in the text.

public BidiOrder(sbyte[] types)

Parameters

types sbyte[]

the types array

BidiOrder(sbyte[], sbyte)

Initialize using an array of direction types and an externally supplied paragraph embedding level. The embedding level may be -1, 0, or 1. -1 means to apply the default algorithm (rules P2 and P3), 0 is for LTR paragraphs, and 1 is for RTL paragraphs.

public BidiOrder(sbyte[] types, sbyte paragraphEmbeddingLevel)

Parameters

types sbyte[]

the types array

paragraphEmbeddingLevel sbyte

the externally supplied paragraph embedding level.
