protected static enum LegacyDeserializationObjectInputStream.LegacyFunctionType extends Enum<LegacyDeserializationObjectInputStream.LegacyFunctionType> implements AggregateFunction
FunctionType
and
AggregateFunction
interfaces which still adheres to the
constant/enum values of the old FunctionType definition. While
deserializing old FunctionType objects, we will convert them to this
enum.Modifier and Type | Method and Description |
---|---|
AggregateBuilder<?> |
createAggregateBuilder()
Creates a specific aggregate builder.
|
Object |
evaluate(Object... values)
Shorthand for creating an aggregate builder, adding all
the values and then calculating the value.
|
ColumnType |
getExpectedColumnType(ColumnType type)
Returns the function ColumnType.
|
String |
getFunctionName() |
static LegacyDeserializationObjectInputStream.LegacyFunctionType |
valueOf(String name)
Returns the enum constant of this type with the specified name.
|
static LegacyDeserializationObjectInputStream.LegacyFunctionType[] |
values()
Returns an array containing the constants of this enum type, in
the order they are declared.
