类 RangeSetBuilder<C extends Comparable>

java.lang.Object

org.tikv.common.expression.Visitor<R,C>

org.tikv.common.expression.visitor.DefaultVisitor<com.google.common.collect.RangeSet<C>,Void>

org.tikv.common.expression.visitor.RangeSetBuilder<C>

直接已知子类:

IndexRangeSetBuilder, PrunedPartitionBuilder

public class RangeSetBuilder<C extends Comparable>
extends DefaultVisitor<com.google.common.collect.RangeSet<C>,Void>

A builder can build a range set of type C. It also extends DefaultVisitor and override and LogicalBinaryExpression's visit. For ComparisonBinaryExpression, we cannot just override it because IndexRangeSetBuilder and LogicalBinaryExpression has different behavior. A method visitComparisonBinaryExpr is added with extra boolean variable to control the behavior.

visit

protected com.google.common.collect.RangeSet<C> visit(LogicalBinaryExpression node,
                                                      Void context)

覆盖:

visit 在类中 DefaultVisitor<com.google.common.collect.RangeSet<C extends Comparable>,Void>

buildRange

public com.google.common.collect.RangeSet<C> buildRange(Expression predicate)

process

protected com.google.common.collect.RangeSet<C> process(Expression node,
                                                        Void context)

覆盖:

process 在类中 DefaultVisitor<com.google.common.collect.RangeSet<C extends Comparable>,Void>
