Public方法
boolean
enoughToFilter()

Instead of filtering whenever the total length of the text exceeds the threshhold, this subclass filters only when the length of the range from
findTokenStart(CharSequence, int)
 to
getSelectionEnd()
 meets or exceeds
getThreshold()
.

当文本的总长度超过阈值时，它不会过滤，只有当从
findTokenStart(CharSequence, int)
到
getSelectionEnd()
的范围的长度达到或超过
getThreshold()
时，这个子类才会过滤。
