Method Details

wrapStringOnBreaks

public static Iterable<String> wrapStringOnBreaks(@Nonnull
 String string,
 int maxWidth)

Splits the given string into lines of maximum width maxWidth. The splitting is done using the current locale's rules for splitting lines.

Parameters:

string - The string to split

maxWidth - The maximum length of any line

Returns:

An iterable of Strings containing the wrapped lines

wrapString

public static String[] wrapString(@Nonnull
 String str,
 int maxWidth,
 @Nullable
 String[] output)

Splits the given string into lines using on any embedded newlines, and wrapping the text as needed to conform to the given maximum line width. This uses and assumes unix-style newlines

Parameters:

str - The string to split

maxWidth - The maximum length of any line

output - If given, try to use this array as the return value. If there are more values than will fit into the array, a new array will be allocated and returned, while the given array will be filled with as many lines as would fit.

Returns:

The split lines from the original, as an array of Strings. The returned array may be larger than the number of lines. If this is the case, the end of the split lines will be denoted by a null entry in the array. If there is no null entry, then the size of the array exactly matches the number of lines. The returned lines will not contain an ending newline
