Detailed Description

A TupleRow encapsulates a contiguous sequence of Tuple pointers which together make up a row.

TupleRow* impala::TupleRow::DeepCopy	(	const std::vector< TupleDescriptor * > &	descs,
		MemPool *	pool
	)

inline

Create a deep copy of this TupleRow. DeepCopy will allocate from the pool.

void impala::TupleRow::DeepCopy	(	TupleRow *	dst,
		const std::vector< TupleDescriptor * > &	descs,
		MemPool *	pool,
		bool	reuse_tuple_mem
	)

inline

Create a deep copy of this TupleRow into 'dst'. DeepCopy will allocate from the MemPool and copy the tuple pointers, the tuples and the string data in the tuples. If reuse_tuple_mem is true, it is assumed the dst TupleRow has already allocated tuple memory and that memory will be reused. Otherwise, new tuples will be allocated and stored in 'dst'.
