Member Function Documentation

VisitOperator()

virtual void duckdb::LogicalOperatorVisitor::VisitOperator ( LogicalOperator &  op )

virtual

Reimplemented in duckdb::ColumnBindingReplacer.

VisitExpression()

virtual void duckdb::LogicalOperatorVisitor::VisitExpression ( unique_ptr< Expression > *  expression )

virtual

Reimplemented in duckdb::ColumnBindingReplacer.

VisitOperatorChildren()

void duckdb::LogicalOperatorVisitor::VisitOperatorChildren ( LogicalOperator &  op )

protected

Automatically calls the Visit method for LogicalOperator children of the current operator. Can be overloaded to change this behavior.

VisitOperatorExpressions()

void duckdb::LogicalOperatorVisitor::VisitOperatorExpressions ( LogicalOperator &  op )

protected

Automatically calls the Visit method for Expression children of the current operator. Can be overloaded to change this behavior.
