Method Detail

canConnect

public boolean canConnect(Hash from,
                          Hash to)

Can "from" connect to "to" based on published addresses? This is intended for tunnel candidates, where we already have the RI. Will not force RI lookups. Either from or to may be us. This is best effort, as we can't know for sure. Published addresses or introducers may have changed. Even if a can't connect to b, they may already be connected as b connected to a.

Returns:

true if we don't have either RI

canConnect

public boolean canConnect(int ourMask,
                          RouterInfo to)

Can we connect to "to" based on published addresses? This is intended for tunnel candidates, where we already have the RI. Will not force RI lookups. This is best effort, as we can't know for sure. Does not check isEstablished(); do that first.

canConnect

public boolean canConnect(RouterInfo from,
                          int ourMask)

Can "from" connect to us based on published addresses? This is intended for tunnel candidates, where we already have the RI. Will not force RI lookups. This is best effort, as we can't know for sure. Does not check isEstablished(); do that first.

getConnectMask

protected static int getConnectMask(Collection<RouterAddress> addrs)

Parameters:

addrs - non-empty, set your own default if empty

Returns:

bitmask of v4/v6 NTCP/SSU

getInboundMask

public int getInboundMask(RouterInfo us)

Our inbound mask. For most cases, we use what we published, i.e. getConnectMask()

Returns:

bitmask for accepting connections

getOutboundMask

public int getOutboundMask(RouterInfo us)

Our outbound mask. For most cases, we use our comm system status.

Returns:

bitmask for initiating connections

isNTCPDisabled

protected boolean isNTCPDisabled()

Is NTCP disabled?

isSSUDisabled

protected boolean isSSUDisabled()

Is SSU disabled?
