Class Summary

Class	Description
BuiltInSqlFunction	SQL version of BuiltInFunctionDefinition in cases where BridgingSqlFunction does not apply.
BuiltInSqlFunction.Builder	Builder for fluent definition of built-in functions.
FlinkSqlOperatorTable	Operator table that contains only Flink-specific functions and operators.
FlinkSqlTimestampFunction	Function that used to define SQL time function like LOCALTIMESTAMP, CURRENT_TIMESTAMP, CURRENT_ROW_TIMESTAMP(), NOW() in Flink, the function support configuring the return type and the precision of return type.
MatchRowTimeFunction	The function used to access a rowtime attribute with TIMESTAMP or TIMESTAMP_LTZ type from MATCH_RECOGNIZE clause.
SqlArrayConstructor	SqlOperator for ARRAY, which makes explicit casting if the element type not equals the derived component type.
SqlCumulateTableFunction	SqlCumulateTableFunction implements an operator for cumulative.
SqlDescriptorOperator	DESCRIPTOR appears as an argument in a function.
SqlFirstLastValueAggFunction	FIRST_VALUE and LAST_VALUE aggregate functions return the first or the last value in a list of values that are input to the function.
SqlHopTableFunction	SqlHopTableFunction implements an operator for hopping.
SqlJsonObjectFunction	This class has been copied from Calcite to backport the fix made during CALCITE-4394.
SqlListAggFunction	LISTAGG aggregate function returns the concatenation of a list of values that are input to the function.
SqlMapConstructor	SqlOperator for MAP, which makes explicit casting if the element type not equals the derived component type.
SqlThrowExceptionFunction	Function used to throw an exception, only used internally.
SqlTryCastFunction	This class implements the TRY_CAST built-in, essentially delegating all the method invocations, whenever is possible, to Calcite's SqlCastFunction.
SqlTumbleTableFunction	SqlTumbleTableFunction implements an operator for tumbling.
SqlWindowTableFunction	Base class for a table-valued function that computes windows.
SqlWindowTableFunction.AbstractOperandMetadata	Partial implementation of operand type checker.
