Class StringBuilders.Repeat

java.lang.Object
org.apache.sis.util.StringBuilders.Repeat
All Implemented Interfaces:
CharSequence
Enclosing class:
StringBuilders
private static final class StringBuilders.Repeat extends Object implements CharSequence
A sequence of a constant character. This implementation does not perform any argument check since it is for StringBuilder.append(CharSequence, int, int) usage only. The intent is to allow StringBuilder to append the characters in one operation instead of looping on StringBuilder.insert(int, char) (which would require memory move on each call).
