Position |
notifyPos(Position pos)
Adds a Position to the Position participating in the first|last determination by assigning it a unique position index. |
void |
removeWordSpace(java.util.List oldList)
Remove the word space represented by the given elements |
void |
setFinished(boolean isFinished)
Set a flag indicating whether the LayoutManager has laid out all its content. |
void |
