All Implemented Interfaces:

BlockStatistics

public class BlockContentManager
extends AbstractBlockContentManager

BlockHandler is responsible for breaking blocks of text into rows. BlockProperties such as list numbers, leaders and margins are resolved in the process. The input text is filtered using the supplied StringFilter before breaking into rows, since the length of the text could change.
