Method Detail

createSubRecord

public static SubRecord createSubRecord(LittleEndianInput in,
                                        int cmoOt)

read a sub-record from the supplied stream

Parameters:

in - the stream to read from

cmoOt - the objectType field of the containing CommonObjectDataSubRecord, we need it to propagate to next sub-records as it defines what data follows

Returns:

the created sub-record

getDataSize

protected abstract int getDataSize()

Returns:

the size of the data for this record (which is always 4 bytes less than the total record size). Note however, that ushort encoded after the record sid is usually but not always the data size.

serialize

public byte[] serialize()

serialize

public abstract void serialize(LittleEndianOutput out)

clone

public abstract java.lang.Object clone()

Overrides:

clone in class java.lang.Object

isTerminating

public boolean isTerminating()

Wether this record terminates the sub-record stream. There are two cases when this method must be overridden and return true - EndSubRecord (sid = 0x00) - LbsDataSubRecord (sid = 0x12)

Returns:

whether this record is the last in the sub-record stream
