Method Detail

createCommand

protected final void createCommand()

completeCommand

public final void completeCommand()

Signal the completion of a DSS Layer A object.

The length of the DSS object will be calculated based on the difference between the start of the DSS, saved in the variable dssLengthLocation_, and the current offset into the buffer which marks the end of the data.

In the event the length requires the use of continuation DSS headers, one for each 32k chunk of data, the data will be shifted and the continuation headers will be inserted with the correct values as needed. Note: In the future, we may try to optimize this approach in an attempt to avoid these shifts.

updateLengthBytes

protected final void updateLengthBytes()

markLengthBytes

protected final void markLengthBytes(int codePoint)
