Class DefaultOperandTypeChecker

java.lang.Object

org.apache.druid.sql.calcite.expression.DefaultOperandTypeChecker

All Implemented Interfaces:

org.apache.calcite.sql.type.SqlOperandTypeChecker

public class DefaultOperandTypeChecker
extends Object
implements org.apache.calcite.sql.type.SqlOperandTypeChecker

Operand type checker that is used in 'simple' situations: there are a particular number of operands, with particular types, some of which may be optional or nullable, and some of which may be required to be literals.
