Method Summary

boolean	equals(Object o) All Tuples should override equals and hashCode.
<T> T	get(Expression<T> expr) Get a tuple element by expression
<T> T	get(int index, Class<T> type) Get a Tuple element by index
int	hashCode() All Tuples should override equals and hashCode.
Object[]	toArray() Get the content as an Object array

Method Detail

get

@Nullable
<T> T get(int index,
                   Class<T> type)

Get a Tuple element by index

Type Parameters:

T -

Parameters:

index -

type -

Returns:

get

@Nullable
<T> T get(Expression<T> expr)

Get a tuple element by expression

Type Parameters:

T -

Parameters:

expr -

Returns:

toArray

Object[] toArray()

Get the content as an Object array

Returns:

equals

boolean equals(Object o)

All Tuples should override equals and hashCode. For compatibility across different Tuple implementations, equality check should use Arrays.equals(Object[], Object[]) with toArray() as parameters.

Overrides:

equals in class Object

See Also:

Object.equals(Object)

hashCode

int hashCode()

All Tuples should override equals and hashCode. For compatibility across different Tuple implementations, hashCode should use Arrays.hashCode(Object[]) with toArray() as parameter.

Overrides:

hashCode in class Object

Object.hashCode()
