LeafBlockWrapper	getOffsetRespBlockBefore(AbstractBlockWrapper block) Selects target wrapped block by the following algorithm: Filter blocks registered via setOffsetRespBlock(LeafBlockWrapper) in order to process only those that start before the given block (blocks which start offset is lower than start offset of the given block).

getOffsetRespBlockBefore

public LeafBlockWrapper getOffsetRespBlockBefore(AbstractBlockWrapper block)

Selects target wrapped block by the following algorithm:

1. Filter blocks registered via setOffsetRespBlock(LeafBlockWrapper) in order to process only those that start before the given block (blocks which start offset is lower than start offset of the given block).
2. Try to find out result from those filtered blocks using the following algorithm:
   1. Use the last block (block which has the greatest start offset) after the block which white space contains line feeds;
   2. Use the first block (block with the smallest start offset) if no block can be selected using the rule above;
   3. Use the last block (block with the greatest start offset) if no block can be selected using the rules above;
3. Delegate the task to the parent alignment (if it's registered) if no blocks are configured for the current one;

Parameters:

block - target block to use during blocks filtering

Returns:

block registered for the current alignment object or its parent using the algorithm above if any; null otherwise

setOffsetRespBlock

public void setOffsetRespBlock(LeafBlockWrapper block)

Registers wrapped block within the current alignment in order to use it for further getOffsetRespBlockBefore(AbstractBlockWrapper) calls processing.

Parameters:

block - wrapped block to register within the current alignment object

getOffsetResponsibleBlocks

public java.util.Set<LeafBlockWrapper> getOffsetResponsibleBlocks()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
