Constructor Detail

ZLDBackendState

ZLDBackendState(BookMetaData bookMetaData)
          throws BookException

This is default package access for forcing the use of the OpenFileStateManager to manage the creation. Not doing so may result in new instances of OpenFileState being created for no reason, and as a result, if they are released to the OpenFileStateManager by mistake this would result in leakage

Parameters:

bookMetaData - the appropriate metadata for the book

Throws:

BookException

getZdtRaf

public RandomAccessFile getZdtRaf()

public void setLastBlockNum(long lastBlockNum)

Parameters:

public void setLastUncompressed(byte[] lastUncompressed)

Parameters:

lastUncompressed - the lastUncompressed to set
