                                           boolean protectDomain)

Compares and puts the data if the compare matches

Parameters:

locationKey - The location key

domainKey - The domain key

hashDataMap - The map with the data and the hashes to compare to

publicKey - The public key

partial - If set to true, then partial puts are OK, otherwise all the data needs to be absent.

protectDomain - Flag to protect domain

Returns:

The keys that have been stored

public void checkTimeout()

digest

public DigestInfo digest(Number160 locationKey,
                         Number160 domainKey,
                         SimpleBloomFilter<Number160> keyBloomFilter,
                         SimpleBloomFilter<Number160> contentBloomFilter)

Description copied from interface: Digest

Calculates a digest over a specific location and domain. It will return those content keys that match the Bloom filter. Those keys that are not stored are ignored

Specified by:

digest in interface Digest

Parameters:

locationKey - The location key

domainKey - The domain key

keyBloomFilter - The bloomFilter of those key elements we want the digest. Please not that there might be false positive, e.g., a Number160 that is included in the digest but not stored on disk/memory.

contentBloomFilter - The bloomFilter of those data elements we want the digest. Please not that there might be false positive, e.g., a Number160 that is included in the digest but not stored on disk/memory.

Returns:

A list of all hashes for the content keys. To return a predictable amount (important for routing), the hashes can be xored.

digest

public DigestInfo digest(Number160 locationKey,
                         Number160 domainKey,
                         Collection<Number160> contentKeys)

Description copied from interface: Digest

Calculates a digest over a specific location and domain. It will return those content keys that are stored. Those keys that are not stored are ignored

Specified by:

digest in interface Digest

Parameters:

locationKey - The location key

domainKey - The domain key

contentKeys - The content keys to look for. Those keys that are not found are ignored. Can be set to null -> gets the information for all content keys

Returns:

A list of all hashes for the content keys. To return a predictable amount (important for routing), the hashes can be xored.
