static CharSequence |
subSequence(CharSequence cs,

Returns a new
CharSequence that is a subsequence of this
sequence starting with the char value at the specified index. |
public CharSequenceUtils()
CharSequenceUtils instances should NOT be constructed in
standard programming.
This constructor is public to permit tools that require a JavaBean instance to operate.
public static CharSequence subSequence(CharSequence cs, int start)
Returns a new CharSequence that is a subsequence of this
sequence starting with the char value at the specified index.
This provides the CharSequence equivalent to String.substring(int).
The length (in char) of the returned sequence is length() - start,
so if start == end then an empty sequence is returned.
cs - the specified subsequence, null returns nullstart - the start index, inclusive, validIndexOutOfBoundsException - if start is negative or if
start is greater than length()Copyright © 2020 Internet2. All rights reserved.
