strip

public static CharSequence strip(CharSequence s)

Unicode-aware edge stripping equivalent to String.strip() for CharSequence.

stripStart

public static int stripStart(CharSequence s,
 int start,
 int length)

Returns the inclusive start index of the trimmed slice after Unicode whitespace stripping.

This is intended for slice-oriented parsing code that wants trimmed bounds without first creating a CharSequence.subSequence(int, int) view. Paired with stripEnd(CharSequence, int, int), callers can decide whether a slice changed and only materialize a subsequence if the downstream parser requires one.

Typical usage:

 int strippedOffset = Strings.stripStart(s, offset, length);
 int strippedEnd = Strings.stripEnd(s, offset, length);
 if (strippedOffset < strippedEnd)
 {
     CharSequence candidate = s.subSequence(strippedOffset, strippedEnd);
 }
 

This is generally preferable to a hypothetical strip(CharSequence, int, int) helper for low-level parsing, because it lets the caller keep control of whether a new view object is created.

stripEnd

public static int stripEnd(CharSequence s,
 int start,
 int length)

Returns the exclusive end index of the trimmed slice after Unicode whitespace stripping.

The returned value follows the normal Java start/end convention used by CharSequence.subSequence(int, int) and String.substring(int, int):

- start is inclusive

- end is exclusive
