using ddl::FTS::Inserter::Handlers = std::array<Handler, FTS_NUM_AUX_INDEX>

Constructor & Destructor Documentation

Inserter()

ddl::FTS::Inserter::Inserter ( Context &  ctx, Dup *  dup, bool  doc_id_32_bit  )

noexcept

Constructor.

Parameters

[in,out]	ctx	DDL context.
[in,out]	dup	Descriptor of FTS index being created.
[in]	doc_id_32_bit	Size of the doc ID column to use for sort.

~Inserter()

ddl::FTS::Inserter::~Inserter ( )

inlinenoexcept

Destructor.

Member Function Documentation

add_file()

dberr_t ddl::FTS::Inserter::add_file ( size_t  id, file_t  file  )

inlinenoexcept

Add a file to the handler for merging and inserting.

Parameters

[in]	id	Aux index ID.
[in]	file	File to merge and insert.

Returns

DB_SUCCESS or error code.

insert()

dberr_t ddl::FTS::Inserter::insert ( Builder *  builder, Inserter::Handler *  handler  )

noexcept

Read sorted file(s) containing index data tuples and insert these data tuples to the index.

Parameters

[in,out]	builder	Index builder.
[in,out]	handler	Insert handler.

Returns

DB_SUCCESS or error number

insert_tuple()

void ddl::FTS::Inserter::insert_tuple ( Insert *  ins_ctx, fts_tokenizer_word_t *  word, ib_vector_t *  positions, doc_id_t *  in_doc_id, const dtuple_t *  dtuple  )

noexcept

Read sorted FTS data files and insert data tuples to auxiliary tables.

Parameters

[in]	ins_ctx	Insert context.
[in]	word	Last processed tokenized word.
[in]	positions	Word position.
[in]	in_doc_id	Last item doc id.
[in]	dtuple	Entry to insert or nullptr on end.

write_node()

dberr_t ddl::FTS::Inserter::write_node ( const Insert *  ins_ctx, const fts_string_t *  word, const fts_node_t *  node  )

noexcept

Write out a single word's data as new entry/entries in the INDEX table.

Parameters

[in]	ins_ctx	Insert context.
[in]	word	Word string.
[in]	node	Node columns.

Returns

DB_SUCCUESS if insertion runs fine, otherwise error code

write_word()

dberr_t ddl::FTS::Inserter::write_word ( Insert *  ins_ctx, fts_tokenizer_word_t *  word  )

noexcept

Insert processed FTS data to auxiliary index tables.

Parameters

[in]	ins_ctx	Insert context.
[in]	word	Sorted and tokenized word.

Returns

DB_SUCCESS if insertion runs fine
