int	getHashSizeBytes()
SecureHistory	open(java.lang.String name, boolean readonly)

Method Detail

create

SecureHistory create(java.lang.String name,
                     long baseSeq,
                     Hash baseHash)
                     throws java.io.IOException

Creates a new history (aka log). Histories are stored as two files: The 'index' file has a fixed-size record for each entry, which contains the sequence number, content and node hashes, as well as an index into the data file. The 'data' file just contains the raw bytes for each entry. Note that the caller must specify the node hash and the sequence number of the first log entry, which forms the base of the hash chain.

Throws:

java.io.IOException

open

SecureHistory open(java.lang.String name,
                   boolean readonly)
                   throws java.io.IOException

Throws:

java.io.IOException
