Member Function Documentation

virtual void tsa::out_stream_adaptor::osa__append ( const date_time &  time_stamp, std::vector< variant > &  record  )

pure virtual

Implement this member in any derived class and to append a new record and time_stamp.

Parameters

	time_stamp	The time stamp.
[in,out]	record	The record.

Implemented in tsa::mem_table, and tsa::fast::table.

virtual void tsa::out_stream_adaptor::osa__prepare_stream ( const std::string &  stream_name, const column_defs &  field_list  )

pure virtual

Implement this member in any derived class. This member is called before any records are passed. Use it for initialization purposes, such as creating a new table in a series_base.

Parameters

stream_name	Name of the stream.
field_list	List of fields.

Implemented in tsa::mem_table, and tsa::fast::table.
