computeLineBreaks

@Nonnull
public static LineBreaker.Result computeLineBreaks(@Nullable
 MeasuredText measuredText,
 @Nonnull
 LineBreaker.ParagraphConstraints constraints,
 @Nullable
 int[] indents,
 int lineNumber)

Break paragraph into lines.

The result is filled to out param.

Parameters:

measuredText - a result of the text measurement

constraints - constraints for a single paragraph

indents - the supplied array provides the total amount of indentation per line, in pixel. This amount is the sum of both left and right indentations. For lines past the last element in the array, the indentation amount of the last element is used.

lineNumber - a line number (index offset) of this paragraph

Returns:

the result of line break
