Member Function Documentation
◆ bitsPerRecord()

Implements e57::BitpackEncoder.
References e57::E57_SINGLE, and precision_.
◆ processRecords()
|
overridevirtual |
Before we add any more, try to shift current contents of outBuffer_ down to beginning of buffer. This leaves outBufferEnd_ at a natural boundary.
Figure out how many records will fit in output.
Can't process more records than will safely fit in output stream
Form the starting address for next available location in outBuffer
Copy floats from sourceBuffer_ to outBuffer_
E57_DOUBLE precision
Form the starting address for next available location in outBuffer
Copy doubles from sourceBuffer_ to outBuffer_
Update end of outBuffer
Update counts of records processed
Implements e57::BitpackEncoder.

◆ registerFlushToOutput()
|
overridevirtual |
Since have no registers in encoder, return success
