Member Function Documentation

◆ get_message_data_and_reset()

virtual Gcs_message_data * Transaction_message_interface::get_message_data_and_reset ( )

pure virtual

Get the Gcs_message_data object, which contains the serialized transaction data.

The internal Gcs_message_data is nullified, to avoid further usage of this Transaction object and the caller receives a pointer to the previously internal Gcs_message_data, which whom it is now responsible.

Returns: the serialized transaction data in a Gcs_message_data object

Implemented in Transaction_message, and Transaction_with_guarantee_message.

◆ length()

virtual uint64_t Transaction_message_interface::length ( )

pure virtual

Length of the message.

Returns: message length
