◆ sp_instr_hpop()

sp_instr_hpop::sp_instr_hpop	(	uint	ip,
		sp_pcontext *	ctx
	)

inline

Member Function Documentation

◆ execute()

bool sp_instr_hpop::execute	(	THD *	thd,
		uint *	nextp
	)

overridevirtual

Execute this instruction.

Parameters

	thd	Thread context
[out]	nextp	index of the next instruction to execute. (For most instructions this will be the instruction following this one). Note that this parameter is undefined in case of errors, use get_cont_dest() to find the continuation instruction for CONTINUE error handlers.

Returns: Error status.

Implements sp_instr.

◆ get_psi_info()

PSI_statement_info * sp_instr_hpop::get_psi_info ( )

inlineoverridevirtual

Implements sp_instr.

◆ print()

void sp_instr_hpop::print	(	const THD *	,
		String *	str
	)

inlineoverridevirtual

Implements sp_printable.

◆ type()

enum Instr_type sp_instr_hpop::type ( )

inlineoverridevirtual

Get the instruction type of this instruction.

Returns: the instruction type

Implements sp_instr.
