Method Detail

formatInBuffer

public int formatInBuffer(byte[] buff)

Formats this track point in a buffer so that it can be written to the log. Values are formatted in order to be readable as csv values.

Overrides:

formatInBuffer in class GeoPoint

Parameters:

buff - buffer to write in.

Returns:

Length of the formatted values in the buffer.

readFromLogLine

public boolean readFromLogLine(java.lang.String logLine)

Fill in attributes of this point from a string generated by the PositionTracer log function.

Overrides:

readFromLogLine in class GeoPoint

Parameters:

logLine - Input string to interpret.

Returns:

true if the string looks correct, false otherwise.

copyFrom

public void copyFrom(java.lang.Object param)

Description copied from class: MeasuredPoint

Copy all elements of point param into this instance.

Overrides:

copyFrom in class MeasuredPoint

Parameters:

param - Point to copy from.
