VString& Vertica::PartitionWriterStringColumn::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

vsize Vertica::PartitionWriterStringColumn::getMaxSize ( )
inline

Returns the maximum size that can be set in the objects returned from append()

const VString& Vertica::PartitionWriterStringColumn::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
