Method Detail

getInstance

public static SafeHtmlBidiFormatter getInstance(boolean rtlContext)

Factory for creating an instance of SafeHtmlBidiFormatter given the context direction. The default behavior of spanWrap(com.google.gwt.safehtml.shared.SafeHtml) and its variations is set to avoid span wrapping unless it's necessary ('dir' attribute needs to be set).

Parameters:

rtlContext - Whether the context direction is RTL. In one simple use case, the context direction would simply be the locale direction, which can be retrieved using LocaleInfo.getCurrentLocale().isRTL()

getInstance

public static SafeHtmlBidiFormatter getInstance(boolean rtlContext,
                                boolean alwaysSpan)

Factory for creating an instance of SafeHtmlBidiFormatter given the context direction and the desired span wrapping behavior (see below).

Parameters:

rtlContext - Whether the context direction is RTL. See an example of a simple use case at getInstance(boolean)

alwaysSpan - Whether spanWrap(com.google.gwt.safehtml.shared.SafeHtml) (and its variations) should always use a 'span' tag, even when the input direction is neutral or matches the context, so that the DOM structure of the output does not depend on the combination of directions

getInstance

public static SafeHtmlBidiFormatter getInstance(HasDirection.Direction contextDir)

Factory for creating an instance of SafeHtmlBidiFormatter given the context direction. The default behavior of spanWrap(com.google.gwt.safehtml.shared.SafeHtml) and its variations is set to avoid span wrapping unless it's necessary ('dir' attribute needs to be set).

Parameters:

contextDir - The context direction. See an example of a simple use case at getInstance(boolean). Note: Direction.DEFAULT indicates unknown context direction. Try not to use it, since it is impossible to reset the direction back to the context when it is unknown

getInstance

public static SafeHtmlBidiFormatter getInstance(HasDirection.Direction contextDir,
                                boolean alwaysSpan)

Factory for creating an instance of SafeHtmlBidiFormatter given the context direction and the desired span wrapping behavior (see below).

Parameters:

contextDir - The context direction. See an example of a simple use case at getInstance(boolean). Note: Direction.DEFAULT indicates unknown context direction. Try not to use it, since it is impossible to reset the direction back to the context when it is unknown

alwaysSpan - Whether spanWrap(com.google.gwt.safehtml.shared.SafeHtml) (and its variations) should always use a 'span' tag, even when the input direction is neutral or matches the context, so that the DOM structure of the output does not depend on the combination of directions

getInstanceForCurrentLocale

public static SafeHtmlBidiFormatter getInstanceForCurrentLocale()

Factory for creating an instance of SafeHtmlBidiFormatter whose context direction matches the current locale's direction. The default behavior of spanWrap(com.google.gwt.safehtml.shared.SafeHtml) and its variations is set to avoid span wrapping unless it's necessary ('dir' attribute needs to be set).

getInstanceForCurrentLocale

public static SafeHtmlBidiFormatter getInstanceForCurrentLocale(boolean alwaysSpan)

Factory for creating an instance of SafeHtmlBidiFormatter whose context direction matches the current locale's direction, and given the desired span wrapping behavior (see below).

Parameters:

alwaysSpan - Whether spanWrap(com.google.gwt.safehtml.shared.SafeHtml) (and its variations) should always use a 'span' tag, even when the input direction is neutral or matches the context, so that the DOM structure of the output does not depend on the combination of directions
