Detailed Description

template<is_producable T>
struct o2::framework::WritingCursor< T >

Helper class actually implementing the cursor which can write to a table. The provided template arguments are if type Column and therefore refer only to the persisted columns.

lastIndex()

template<is_producable T>

int64_t o2::framework::WritingCursor< T >::lastIndex ( )

inline

Last index inserted in the table.

Definition at line 523 of file AnalysisHelpers.h.

operator()()

template<is_producable T>

template<typename... Ts>
requires (sizeof...(Ts) == framework::pack_size(typename persistent_table_t::persistent_columns_t{}))

void o2::framework::WritingCursor< T >::operator() ( Ts &&...  args )

inline

Definition at line 507 of file AnalysisHelpers.h.

release()

template<is_producable T>

void o2::framework::WritingCursor< T >::release ( )

inline

Definition at line 555 of file AnalysisHelpers.h.

reserve()

template<is_producable T>

void o2::framework::WritingCursor< T >::reserve ( int64_t  size )

inline

reserve size rows when filling, so that we do not spend time reallocating the buffers. Switches the internal cursor to UnsafeAppend (no capacity check), which is safe because we just reserved enough space.

Definition at line 548 of file AnalysisHelpers.h.

resetCursor()

template<is_producable T>

bool o2::framework::WritingCursor< T >::resetCursor ( LifetimeHolder< TableBuilder >  builder )

inline

setLabel()

template<is_producable T>

void o2::framework::WritingCursor< T >::setLabel ( const char *  label )

inline
