Uses of RexVisitor in org.apache.calcite.plan

Classes in org.apache.calcite.plan that implement RexVisitor

Modifier and Type	Class and Description
static class	RelOptUtil.InputFinder Visitor which builds a bitmap of the inputs used by an expression.
static class	RelOptUtil.InputReferencedVisitor Shuttle that finds the set of inputs that are used.
static class	RelOptUtil.RexInputConverter Walks an expression tree, converting the index of RexInputRefs based on some adjustment factor.
static class	RelOptUtil.VariableUsedVisitor Visitor that finds all variables used in an expression.

Uses of RexVisitor in org.apache.calcite.rel.rules

Classes in org.apache.calcite.rel.rules that implement RexVisitor

Modifier and Type	Class and Description
class	ReduceDecimalsRule.DecimalShuttle A shuttle which converts decimal expressions to expressions based on longs.

Uses of RexVisitor in org.apache.calcite.rex

Classes in org.apache.calcite.rex that implement RexVisitor

Modifier and Type	Class and Description
class	RexChecker Visitor which checks the validity of a RexNode expression.
class	RexPermutationShuttle Visitor which replaces RexLocalRef objects after the expressions in a RexProgram have been reordered.
class	RexPermuteInputsShuttle Shuttle which applies a permutation to its input fields.
class	RexShuttle Passes over a row-expression, calling a handler method for each node, appropriate to the type of the node.
static class	RexUtil.FieldAccessFinder Visitor which builds a bitmap of the inputs used by an expression.
class	RexVisitorImpl<R> Default implementation of RexVisitor, which visits each node but does nothing while it's there.
