Method Detail

create

public static <TUPLE extends org.javatuples.Tuple> TUPLE create(List<?> objects)

Transforms a list of object into a tuple. Does not work array of more than ten element.

Type Parameters:

TUPLE - the tuple type

Parameters:

objects - the list of object

Returns:

a tuple

Throws:

org.seedstack.seed.SeedException - if the array length is greater than 10

create

public static <TUPLE extends org.javatuples.Tuple> TUPLE create(Object firstObject,
                                                                Object... objects)

Transforms an array of object into a tuple. Does not work array of more than ten element.

Type Parameters:

TUPLE - the tuple type

Parameters:

firstObject - the first item of the tuple

objects - the array of object

Returns:

a tuple

Throws:

org.seedstack.seed.SeedException - if the array length is greater than 10

createTupleFromList

@Deprecated
public static <TUPLE extends org.javatuples.Tuple> TUPLE createTupleFromList(Object... objects)

Deprecated. Use the shorter create method instead.

Transforms an array of object into a tuple. Does not work array of more than ten element.

Type Parameters:

TUPLE - the tuple type

Parameters:

objects - the array of object

Returns:

a tuple

Throws:

org.seedstack.seed.SeedException - if the array length is greater than 10

createTupleFromList

@Deprecated
public static <TUPLE extends org.javatuples.Tuple> TUPLE createTupleFromList(List<Object> objects)

Deprecated. Use the shorter create method instead.

Transforms a list of object into a tuple. Does not work array of more than ten element.

Type Parameters:

TUPLE - the tuple type

Parameters:

objects - the list of object

Returns:

a tuple

Throws:

org.seedstack.seed.SeedException - if the array length is greater than 10

classOfTuple

public static Class<? extends org.javatuples.Tuple> classOfTuple(List<?> objects)

classOfTuple

public static Class<? extends org.javatuples.Tuple> classOfTuple(Object... objects)

Finds for a list of object the associated tuple class, eg. a Pair for a list of two objects, a Triplet for a list of three, etc...

Parameters:

objects - the list of objects

Returns:

the tuple class

classOfTuple

public static Class<? extends org.javatuples.Tuple> classOfTuple(int cardinality)

Finds for a cardinality the associated tuple class, eg. a Pair for 2, a Triplet for 3, etc...

Parameters:

cardinality - the cardinality of the tuple

Returns:

the tuple class

typeOfTuple

public static ParameterizedType typeOfTuple(Class<?>... classes)

Gets the final tuple type for a list of class.

For instance, for a list with Customer.class and Order.class the method will return Pair<Customer, Order>.

Parameters:

classes - the tuple's classes

Returns:

the tuple type

toList

public static <T> List<T> toList(org.javatuples.Tuple tuple)

toListOfClasses

public static List<?> toListOfClasses(org.javatuples.Tuple tuple)
