org.graalvm.shadowed.com.ibm.icu.text.BidiTransform.Order

All Implemented Interfaces:

Serializable, Comparable<BidiTransform.Order>, java.lang.constant.Constable

Enclosing class:

BidiTransform

public static enum BidiTransform.Order
extends Enum<BidiTransform.Order>

BidiTransform.Order indicates the order of text.

This bidi transformation engine supports all possible combinations (4 in total) of input and output text order:

• {logical input, visual output}: unless the output direction is RTL, this corresponds to a normal operation of the Bidi algorithm as described in the Unicode Technical Report and implemented by Bidi when the reordering mode is set to Bidi#REORDER_DEFAULT. Visual RTL mode is not supported by Bidi and is accomplished through reversing a visual LTR string,
• {visual input, logical output}: unless the input direction is RTL, this corresponds to an "inverse bidi algorithm" in Bidi with the reordering mode set to Bidi.REORDER_INVERSE_LIKE_DIRECT. Visual RTL mode is not not supported by Bidi and is accomplished through reversing a visual LTR string,
• {logical input, logical output}: if the input and output base directions mismatch, this corresponds to the Bidi implementation with the reordering mode set to Bidi.REORDER_RUNS_ONLY; and if the input and output base directions are identical, the transformation engine will only handle character mirroring and Arabic shaping operations without reordering,
• {visual input, visual output}: this reordering mode is not supported by the Bidi engine; it implies character mirroring, Arabic shaping, and - if the input/output base directions mismatch - string reverse operations.
