Tuple

public Tuple()

方法详细资料

get

public abstract <T> T 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.

set

public abstract <T> void set(T value,
                             int index)

Set the value at the given index.

参数:

value - The object value.

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

copy

public abstract <T extends Tuple> T copy()

Returns a copy of this instance.

返回:

a copy of this instance.

length

public abstract int length()

Returns int value of this tuple elements count.

返回:

int value of this tuple elements count.

toArray

public final 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[].

toString

public final String toString()

Returns a string representation of the object.

覆盖:

toString 在类中 Object

返回:

a string representation of the Tuple.

hashCode

public final int hashCode()

Returns a hash code value for the object.

覆盖:

hashCode 在类中 Object

返回:

a hash code value for this object.

equals

public final boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

覆盖:

equals 在类中 Object

参数:

obj - the reference object with which to compare.

返回:

true if this object equals the other.

equals

public final boolean equals(Object... elements)

Returns tuple elements are equals array elements.

参数:

elements - the elements

返回:

true if elements equals.

compareTo

public final int compareTo(Object o)

指定者:

compareTo 在接口中 Comparable<Object>

toList

public List<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>.

iterator

public Iterator<Object> iterator()

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

指定者:

iterator 在接口中 Iterable<Object>

返回:

An unmodifiable Iterator over the elements in this Tuple.

spliterator

public Spliterator<Object> spliterator()

指定者:

spliterator 在接口中 Iterable<Object>

join

public final String join(CharSequence delimiter,
                         Function<Object,String> valueMapper,
                         CharSequence prefix,
                         CharSequence suffix)

Returns string of joined the tuple elements.

参数:

delimiter - the delimiter

valueMapper - the valueMapper for each element to string function

prefix - the prefix

suffix - the suffix

返回:

string of joined the tuple elements
