Constructor Detail

TmsTrap

public TmsTrap(DataBlock dataBlock)
        throws java.lang.IllegalArgumentException

Constructs a TmsTrap using the 6 bytes of data at offset in dataBlock.

Parameters:

dataBlock - byte array containing data

Throws:

BadOffsetException - if offset is less than the header size or greater than the data block size

java.lang.IllegalArgumentException

Method Detail

read

protected void read(int offset)
             throws BadOffsetException

reads values for a TmsTrap from the 6 bytes of data at offset in dataBlock.

Specified by:

read in class TmsData

Parameters:

offset - offset within dataBlock

Throws:

BadOffsetException - if offset is less than the header size or greater than the data block size reads 6 bytes of data at offset in dataBlock

processSensor
