详细描述

Rule transforms Logical predicate -> Physical predicate TODO: In practice, this rule may not be used and can be removed

void LogicalPredicateToPredicate::transform	(	OperatorNode *	input,
		std::vector< std::unique_ptr< OperatorNode > > *	transformed,
		OptimizerContext *	context
	)		const

overridevirtual

Convert a "before" operator tree to an "after" operator tree

参数

input	The "before" operator tree
transformed	Vector of "after" operator trees
context	The current optimization context
