Pair

public Pair(L key,
            R value)

Creates a new pair

参数:

left - The left for this pair

value - The value to use for this pair

方法详细资料

getLeft

public L getLeft()

Gets the left element from this pair.

When treated as a left-value pair, this is the left.

返回:

the left element, may be null

getRight

public R getRight()

Gets the right element from this pair.

When treated as a left-value pair, this is the value.

返回:

the right element, may be null

getKey

public L getKey()

Gets the left for this pair.

返回:

left for this pair

getValue

public R getValue()

Gets the value for this pair.

返回:

value for this pair

toString

public java.lang.String toString()

String representation of this Pair.

The default name/value delimiter '=' is always used.

覆盖:

toString 在类中 java.lang.Object

返回:

String representation of this Pair

hashCode

public int hashCode()

Generate a hash code for this Pair.

The hash code is calculated using both the name and the value of the Pair.

覆盖:

hashCode 在类中 java.lang.Object

返回:

hash code for this Pair

equals

public boolean equals(java.lang.Object o)

Test this Pair for equality with another Object.

If the Object to be tested is not a Pair or is null, then this method returns false.

Two Pairs are considered equal if and only if both the names and values are equal.

覆盖:

equals 在类中 java.lang.Object

参数:

o - the Object to test for equality with this Pair

返回:

true if the given Object is equal to this Pair else false

of

public static <L,R> Pair<L,R> of(L left,
                                 R right)

Obtains an pair of from two objects inferring the generic types.

This factory allows the pair to be created using inference to obtain the generic types.

类型参数:

L - the left element type

R - the right element type

参数:

left - the left element, may be null

right - the right element, may be null

返回:

a pair formed from the two parameters, not null
