virtual bool Diagnostics_information::aggregate ( THD *  thd, const Diagnostics_area *  da  )

pure virtual

Aggregate diagnostics information.

Parameters

thd	The current thread.
da	The diagnostics area.

Return values

false	on success.
true	on error

Implemented in Condition_information, Statement_information, and get_diagnostics_unittest::MockDiagInfoError.
