Method Detail

ensureDrillBufReadIndexIsZero

public void ensureDrillBufReadIndexIsZero()
                                   throws Exception

Contract for DrillBuf[] returned from getBuffers() is that buffers are returned in a reader appropriate state (i.e., readIndex = 0) Before this patch, the following scenario breaks this contract: As data being read from DrillBuf, readIndex will be pushed forward. And, later on, when DrillBuf[] are read from the ValueVector, readIndex will point at the location of the most recent reading This unit test is added to ensure that the readIndex points at zero under this scenario
