Method Detail

blacklist

void blacklist(Address address,
               boolean permanent)

Adds an address to the blacklist. Blacklist is useful if a node should ignore another node, e.g. when the clustername of 2 machines is not the same and they should form different clusters.

If blacklist is permanent, then this operation is write-once. It cannot be unblacklisted again. If blacklist is temporary, blacklist can be removed via unblacklist(Address).

Method is thread-safe.

If the address already is blacklisted, the call is ignored

Parameters:

address - the address to blacklist.

permanent - true if blacklist is permanent, false if not.

Throws:

NullPointerException - if address is null.

unblacklist

boolean unblacklist(Address address)

Removes an address from the blacklist if it is temporarily blacklisted. This method has no effect if given address is not blacklisted. Permanent blacklists cannot be undone.

Parameters:

address - the address to unblacklist.

Returns:

true if address is unblacklisted, false otherwise.

isBlacklisted

boolean isBlacklisted(Address address)
