Constructor & Destructor Documentation

Row() [1/2]

ddl::Row::Row ( )

default

Constructor.

Row() [2/2]

ddl::Row::Row ( const Row &  )

default

~Row()

ddl::Row::~Row ( )

default

Destructor.

Member Function Documentation

build()

dberr_t Row< T >::build ( ddl::Context &  ctx, mem_heap_t *  heap  )

noexcept

Build a row from a raw record.

It makes m_ptr point to data found in m_rec, m_add_cols, ctx.m_add_v, handling ctx.m_fts.m_doc_id and ctx.m_add_autoinc, too.

Parameters

[in,out]	ctx	DDL context.
[in,out]	heap	Heap to use for allocation.

Returns

DB_SUCCESS or error code.

deep_copy()

void Row< T >::deep_copy ( mem_heap_t *  heap )

noexcept

Makes the row indpendent from the original buffers, i.e.

the m_ptr will point to fresh copies allocated from heap, instead of data inside m_rec, or m_add_cols. The caller should first call build(..).

Parameters

[in]

heap

Heap to use for allocation.

operator=()

Row & ddl::Row::operator= ( const Row &  )

default

Member Data Documentation

m_add_cols

dtuple_t* ddl::Row::m_add_cols {}

Add column data values.

m_ext

row_ext_t* ddl::Row::m_ext {}

Externally stored fields.

m_offsets

ulint* ddl::Row::m_offsets {}

Column offsets.

m_ptr

const dtuple_t* ddl::Row::m_ptr {}

DTuple data, mapped over m_rec.

m_rec

const rec_t* ddl::Row::m_rec {}

Row data.
