Method Detail

equals

public boolean equals(java.lang.Object o)

Compares two protocol IDs

Overrides:

equals in class ProtocolID

Parameters:

o - an object to compare with this object.

Returns:

true iff the supplied object's class is the same as the class of this object.

isActive

public boolean isActive()

Always returns true.

Specified by:

isActive in class ProtocolID

Returns:

boolean indicating whether protocol is active.

requiresUserInteraction

public boolean requiresUserInteraction()

Always returns false.

Specified by:

requiresUserInteraction in class ProtocolID

Returns:

boolean indicating whether user interaction is required.

getLinkBuilder

protected LinkFactory.Builder getLinkBuilder(java.util.Hashtable settings)

Returns the factory builder for this protocol.

Specified by:

getLinkBuilder in class ProtocolID

Parameters:

settings - Hashtable containing settings.

Returns:

the Builder for constructing Links.

startLinkServer

protected LinkServer startLinkServer(NodeAddressID addressID)
