Detailed Description

Represents the diagnostics information to be obtained.

Diagnostic information is made available through statement information and condition information items.

Member Enumeration Documentation

Which diagnostics area to access. Only CURRENT is supported for now.

Enumerator:

CURRENT_AREA

Access the first diagnostics area.

virtual Diagnostics_information::~Diagnostics_information ( ) [inline, protected, virtual]

Diagnostics_information objects are allocated in thd->mem_root. Do not rely on the destructor for any cleanup.

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

template<typename Diag_item , typename Context >

bool Diagnostics_information::evaluate	(	THD *	thd,
		Diag_item *	diag_item,
		Context	ctx
	)		`[inline, protected]`

Evaluate a diagnostics information item in a specific context.

Parameters:

thd	The current thread.
diag_item	The diagnostics information item.
ctx	The context to evaluate the item.

Return values:

false	on success.
true	on error.

Which_area Diagnostics_information::get_which_da ( void ) const [inline]

Get which diagnostics area to access.

void Diagnostics_information::set_which_da ( Which_area area ) [inline]

Set which diagnostics area to access.
