isRtl

public static boolean isRtl(BidiAnalyzer.BidiStrategy strategy,
                            CharSequence text)

Checks whether the general direction of text is RTL based on the specified strategy and the Locale configured in the system.

参数:

strategy - Indicates the bidirectional text recognition strategy.

text - Indicates the text to be recognized.

返回:

Returns true if the general direction of text is RTL; returns false otherwise.

抛出:

IllegalArgumentException - Throws this exception if a specified parameter is empty.

Checks whether the general direction of text is RTL based on the specified strategy and locale.

Ensure that locale is a valid locale ID.

参数:

strategy - Indicates the bidirectional text recognition strategy.

text - Indicates the text to be recognized.

locale - Indicates the locale ID.

返回:

Returns true if the general direction of text is RTL; returns false otherwise.

参数:

strategy - Indicates the bidirectional text recognition strategy.

text - Indicates the text to be recognized.

runs - Indicates a list of the direction division result.

返回:

Returns true if the general direction of text is RTL; returns false otherwise.
