Constructor Detail

TraceStep

public TraceStep()

Construct an empty TraceStep.

TraceStep

public TraceStep(java.lang.String baseCallsign,
                 int ssid,
                 byte networkId)

Construct a TraceStep specifying the relay step taken.

Parameters:

baseCallsign - String callsign of the relaying station

ssid - int SSID of the relaying station

networkId - the OpenTRAC network type used for the relay

Method Detail

computeBody

public int computeBody(byte[] buf,
                       int offset)

Append this element to a message buffer

Parameters:

buf - byte array to add the element to

offset - starting index to store the element

Returns:

index after the end of the stored element

valueString

public java.lang.String valueString()

Get the string representation of the value of this element.

Returns:

value string

equals

public boolean equals(java.lang.Object obj)

Indicates whether some other object is "equal to" this one.

Overrides:

equals in class java.lang.Object

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

hashCode

public int hashCode()

Returns a hash code value for the object.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code value for this object.
