Constructor Detail

PatchworkFaultMsg

public PatchworkFaultMsg(NodeId peer,
                         int value,
                         boolean isPercent)

Constucts a fault injection message, which will let a peer know that it should begin dropping messages. Either an absolute number of messages can be specified, or a percentage of messages for an indefinite amount of time. Note that if a percentage is given, it can be removed by sending another fault injection message with the value at 0. Any arriving fault message overrides the previous one.

Parameters:

peer - the node to contact

value - the amount of messages to drop, either as a number of messages or a percent of messages

isPercent - true if value specifies a percentage

PatchworkFaultMsg

public PatchworkFaultMsg(NodeId peer,
                         int value,
                         boolean isPercent,
                         boolean allNodes)

Constucts a fault injection message, which will let a peer know that it should begin dropping messages. Either an absolute number of messages can be specified, or a percentage of messages for an indefinite amount of time. Note that if a percentage is given, it can be removed by sending another fault injection message with the value at 0. Any arriving fault message overrides the previous one.

Parameters:

peer - the node to contact

value - the amount of messages to drop, either as a number of messages or a percent of messages

isPercent - true if value specifies a percentage

allNodes - true iff this fault is to apply to all nodes probing it

public PatchworkFaultMsg(NodeId peer,
                         int value,
                         boolean isPercent,
                         NodeId nodeToDrop)

Constucts a fault injection message, which will let a peer know that it should begin dropping messages. Either an absolute number of messages can be specified, or a percentage of messages for an indefinite amount of time. Note that if a percentage is given, it can be removed by sending another fault injection message with the value at 0. Any arriving fault message overrides the previous one.

Parameters:

peer - the node to contact

value - the amount of messages to drop, either as a number of messages or a percent of messages

isPercent - true if value specifies a percentage

nodeToDrop - Drop messages from a specific node, instead of sender
