com.pingcap.tikv.expression.visitor中PartitionedTable.PartitionLocatorContext的使用

参数类型为PartitionedTable.PartitionLocatorContext的com.pingcap.tikv.expression.visitor中的方法

限定符和类型	方法和说明
Boolean	RangePartitionLocator.visit(ComparisonBinaryExpression node, PartitionedTable.PartitionLocatorContext context) For ComparisonBinaryExpression such as year(birthday@DATE) GREATER_EQUAL 1995, we need to evaluate the result of the left node and compare it with the right node.
Boolean	RangePartitionLocator.visit(Constant node, PartitionedTable.PartitionLocatorContext context) For partition using MAXVALUE such as "partition p2 values less than MAXVALUE" it will be converted to [[year(birthday@DATE) GREATER_EQUAL ${lower_bound}] AND 1], 1 is Constant standing for always true.
Boolean	RangePartitionLocator.visit(LogicalBinaryExpression node, PartitionedTable.PartitionLocatorContext context) For logicalBinaryExpression such as [[year(birthday@DATE) GREATER_EQUAL 1995] AND [year(birthday@DATE) LESS_THAN 1997]] we need to get the result of these two ComparisonBinaryExpression.
