Member Function Documentation

VNumeric& Vertica::PartitionWriterNumericColumn::append ( )

inline

Returns a reference to the next element to write. Setting its members will update the data in the PartitionWriter

Note that the underlying object is re-used, so the object references should not be retained between calls to append

void Vertica::PartitionWriterNumericColumn::directCopy ( uint64 *  src, size_t  elementsToCopy, int  srcTypMod, size_t  elementSize  )

inline

Elements must be in 2s compliment and in a compatible encoding; check the value of getTypmod to ensure that encodings are identical

const VNumeric& Vertica::PartitionWriterNumericColumn::getRef ( size_t  offset_from_start )

inline

Returns a reference to a previously written element.

Note that the underlying object is re-used, so the object references should not be retained between calls to append

int Vertica::BasePartitionWriterColumn::getStrideLength ( )

inlineinherited

Returns the size of each element in the column
