Method Detail

toString

public java.lang.String toString()

Display the packet in human readable format.

Overrides:

toString in class java.lang.Object

Returns:

The contents of the packet.

isVirtual

public boolean isVirtual()

Determine whether this message is real or virtual.

Returns:

true if the message is virtual, false if the message is real.

isReal

public boolean isReal()

Determine whether this message is real.

Returns:

true if the message is real, false if the message is virtual.

isAnti

public boolean isAnti(AvnmpDriverRb ap)

Determine whether the input packet is an anti-message of this message.

Parameters:

ap - A packet containing a possible anti-message of the current message.

Returns:

true if the input packet is an anti-message of this packet.

isEqual

public boolean isEqual(AvnmpDriverRb ap)

Check if packets are equal. Equality does not include the anti-message toggle or the packet contents.

Parameters:

ap - The packet which is checked for equality with this packet.

Returns:

true if this packet and the input packet are equal, false otherwise.

isGvtUpdateRequest

public boolean isGvtUpdateRequest()

Check if packet is a Gvt start calculation packet.

Returns:

true if this packet is a GVT calculation start packet, false otherwise.

isGvtUpdateResponse

public boolean isGvtUpdateResponse()

Check if packet is a Gvt response calculation packet.

Returns:

true if this packet is a GVT calculation response packet, false otherwise.

isGvtReportInput

public boolean isGvtReportInput()

Check if packet is a Gvt calculation report packet.

Returns:

true if this packet is a GVT calculation report packet, false otherwise.

isAnti

public boolean isAnti()

Check if packet is an anti-message.

Returns:

true if this packet is an anti-message. false otherwise.

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

compareTo

public int compareTo(java.lang.Object o)

exec

public void exec()

This is the main processing for this active packet. The primary task is to add itself to the receiving node's input queue.
