GetSelVector()

idx_t duckdb::ChunkConstantInfo::GetSelVector ( ScanOptions  options, optional_ptr< SelectionVector >  sel_vector, idx_t  max_count  ) const

overridevirtual

Gets up to max_count entries from the chunk info. If the ret is 0>ret>max_count, the selection vector is filled with the tuples

Implements duckdb::ChunkInfo.

Fetch()

bool duckdb::ChunkConstantInfo::Fetch ( TransactionData  transaction, row_t  row  )

overridevirtual

Returns whether or not a single row in the ChunkInfo should be used or not for the given transaction.

Implements duckdb::ChunkInfo.

CommitAppend()

void duckdb::ChunkConstantInfo::CommitAppend ( transaction_t  commit_id, idx_t  start, idx_t  end  )

overridevirtual

Implements duckdb::ChunkInfo.

Cleanup()

bool duckdb::ChunkConstantInfo::Cleanup ( transaction_t  lowest_transaction ) const

overridevirtual

Reimplemented from duckdb::ChunkInfo.

ToString()

string duckdb::ChunkConstantInfo::ToString ( idx_t  max_count ) const

overridevirtual

Implements duckdb::ChunkInfo.

HasDeletes()

bool duckdb::ChunkConstantInfo::HasDeletes ( transaction_t  transaction_id = MAX_TRANSACTION_ID ) const

overridevirtual

Implements duckdb::ChunkInfo.

Write()

void duckdb::ChunkConstantInfo::Write ( WriteStream &  writer, transaction_t  transaction_id  ) const

overridevirtual

Reimplemented from duckdb::ChunkInfo.
