Class ChmLzxBlock

java.lang.Object

org.apache.tika.parser.chm.lzx.ChmLzxBlock

public class ChmLzxBlock
extends Object

Decompresses a chm block. Depending on chm block type chooses most relevant decompressing method. A chm block type can be as follows:

UNDEFINED - no action taken, i.e. skipping the block VERBATIM ALIGNED_OFFSET UNCOMPRESSED the most simplest In addition there are unknown types (4-7). Currently relying on previous chm block these types changing according to the previous chm block type. We need to invent more appropriate way to handle such types.
