All Implemented Interfaces:

Message, VendorMessage, VendorMessage.ControlMessage, Comparable<Message>

public final class MessagesSupportedVendorMessage
extends AbstractVendorMessage
implements VendorMessage.ControlMessage

The message that lets other know what messages you support. Everytime you add a subclass of VendorMessage you should modify this class (assuming your message is delivered over TCP).

supportsTCPConnectBack

public int supportsTCPConnectBack()

Returns:

-1 if the message isn't supported, else it returns the version of the message supported.

supportsUDPConnectBack

public int supportsUDPConnectBack()

Returns:

-1 if the message isn't supported, else it returns the version of the message supported.

supportsTCPConnectBackRedirect

public int supportsTCPConnectBackRedirect()

Returns:

-1 if the message isn't supported, else it returns the version of the message supported.

supportsUDPConnectBackRedirect

public int supportsUDPConnectBackRedirect()

Returns:

-1 if the message isn't supported, else it returns the version of the message supported.

supportsHopsFlow

public int supportsHopsFlow()

Returns:

-1 if the message isn't supported, else it returns the version of the message supported.

supportsPushProxy

public int supportsPushProxy()

Returns:

-1 if the message isn't supported, else it returns the version of the message supported.

supportsLeafGuidance

public int supportsLeafGuidance()

Returns:

Returns:

-1 if the remote host does DHT Conacts exchange, else return the version

equals

public boolean equals(Object other)

Overrides:

equals in class AbstractVendorMessage

Returns:

true if the two VMPs have identical signatures - no more, no less. Does not take version into account, but if different versions have different payloads, they'll differ.

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractVendorMessage

writePayload

protected void writePayload(OutputStream out)
