Method Detail

of

public static TupleType of(DataType... types)

Creates a tuple type given a list of types.

Parameters:

types - the types for the tuple type.

Returns:

the newly created tuple type.

getComponentTypes

public List<DataType> getComponentTypes()

The (immutable) list of types composing this tuple type.

Returns:

the (immutable) list of types composing this tuple type.

newValue

public TupleValue newValue()

Returns a new empty value for this tuple type.

Returns:

an empty (with all component to null) value for this user type definition.

newValue

public TupleValue newValue(Object... values)

Returns a new value for this tuple type that uses the provided values for the components.

The numbers of values passed to this method must correspond to the number of components in this tuple type. The ith parameter value will then be assigned to the ith component of the resulting tuple value.

Parameters:

values - the values to use for the component of the resulting tuple.

Returns:

a new tuple values based on the provided values.

Throws:

IllegalArgumentException - if the number of values provided does not correspond to the number of components in this tuple type.

InvalidTypeException - if any of the provided value is not of the correct type for the component.
