processRecords()

uint64_t BitpackFloatEncoder::processRecords ( size_t  recordCount )

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.

Verify that outBufferEnd_ is multiple of typeSize (so transfers of floats are aligned naturally in memory).

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

registerFlushToOutput()

bool BitpackFloatEncoder::registerFlushToOutput ( )

overridevirtual

Since have no registers in encoder, return success
