方法详细资料

getT1

public T1 getT1()

Type-safe way to get the first object of this Tuples.

返回:

The first object

getT2

public T2 getT2()

Type-safe way to get the second object of this Tuples.

返回:

The second object

mapT1

public <R> Tuple2<R,T2> mapT1(java.util.function.Function<T1,R> mapper)

Map the left-hand part (T1) of this Tuple2 into a different value and type, keeping the right-hand part (T2).

类型参数:

R - the new type for the left-hand part

参数:

mapper - the mapping Function for the left-hand part

返回:

a new Tuple2 with a different left (T1) value

mapT2

public <R> Tuple2<T1,R> mapT2(java.util.function.Function<T2,R> mapper)

Map the right-hand part (T2) of this Tuple2 into a different value and type, keeping the left-hand part (T1).

类型参数:

R - the new type for the right-hand part

参数:

mapper - the mapping Function for the right-hand part

返回:

a new Tuple2 with a different right (T2) value

get

@Nullable
public java.lang.Object get(int index)

Get the object at the given index.

参数:

index - The index of the object to retrieve. Starts at 0.

返回:

The object or null if out of bounds.

toList

public java.util.List<java.lang.Object> toList()

Turn this Tuple into a List<Object>. The list isn't tied to this Tuple but is a copy with limited mutability (add and remove are not supported, but set is).

返回:

A copy of the tuple as a new List<Object>.

toArray

public java.lang.Object[] toArray()

Turn this Tuple into a plain Object[]. The array isn't tied to this Tuple but is a copy.

返回:

A copy of the tuple as a new Object[].

iterator

public java.util.Iterator<java.lang.Object> iterator()

Return an immutable Iterator<Object> around the content of this Tuple.

指定者:

iterator 在接口中 java.lang.Iterable<java.lang.Object>

返回:

An unmodifiable Iterator over the elements in this Tuple.

equals

public boolean equals(@Nullable
                      java.lang.Object o)

覆盖:

equals 在类中 java.lang.Object

hashCode

public int hashCode()

覆盖:

hashCode 在类中 java.lang.Object

size

public int size()

Return the number of elements in this Tuples.

返回:

The size of this Tuples.

toString

public final java.lang.String toString()

A Tuple String representation is the comma separated list of values, enclosed in square brackets.

覆盖:

toString 在类中 java.lang.Object

返回:

the Tuple String representation
