typedef uint8_t UBiDiLevel typedef uint8_t UBiDiLevel UBiDiLevel is the type of the level values in this BiDi implementation
UBiDiLevel is the type of the level values in this BiDi implementation. It holds an embedding level and indicates the visual direction by its bit 0 (even/odd value).It can also hold non-level values for the
paraLevelandembeddingLevelsarguments ofubidi_setPara(); there:
- bit 7 of an
embeddingLevels[]value indicates whether the using application is specifying the level of a character to override whatever the BiDi implementation would resolve it to.paraLevelcan be set to the pesudo-level valuesUBIDI_DEFAULT_LTRandUBIDI_DEFAULT_RTL.
The related constants are not real, valid level values.
UBIDI_DEFAULT_XXX can be used to specify
a default for the paragraph level for
when the ubidi_setPara() function
shall determine it but there is no
strongly typed character in the input.
Note that the value for UBIDI_DEFAULT_LTR is even
and the one for UBIDI_DEFAULT_RTL is odd,
just like with normal LTR and RTL level values -
these special values are designed that way. Also, the implementation
assumes that UBIDI_MAX_EXPLICIT_LEVEL is odd.
