Class ObjDoublePair<A>

java.lang.Object

com.opengamma.strata.collect.tuple.ObjDoublePair<A>

Type Parameters:

A - the type of the object

All Implemented Interfaces:

Tuple, Serializable, Comparable<ObjDoublePair<A>>, org.joda.beans.Bean, org.joda.beans.ImmutableBean

public final class ObjDoublePair<A>
extends Object
implements org.joda.beans.ImmutableBean, Tuple, Comparable<ObjDoublePair<A>>, Serializable

An immutable pair consisting of an Object and a double.

This class is similar to Pair but includes a primitive element.

This class is immutable and thread-safe.

Method Detail

of

public static <A> ObjDoublePair<A> of(A first,
                                      double second)

Obtains an instance from an Object and a double.

Type Parameters:

A - the first element type

Parameters:

first - the first element

second - the second element

Returns:

a pair formed from the two parameters

ofPair

public static <A> ObjDoublePair<A> ofPair(Pair<A,Double> pair)

Obtains an instance from a Pair.

Type Parameters:

A - the first element type

Parameters:

pair - the pair to convert

Returns:

a pair formed by extracting values from the pair

size

public int size()

Gets the number of elements held by this pair.

Specified by:

size in interface Tuple

Returns:

size 2

elements

public ImmutableList<Object> elements()

Gets the elements from this pair as a list.

The list returns each element in the pair in order.

Specified by:

elements in interface Tuple

Returns:

the elements as an immutable list

toPair

public Pair<A,Double> toPair()

Converts this pair to an object-based Pair.

Returns:

the object-based pair

compareTo

public int compareTo(ObjDoublePair<A> other)

Compares the pair based on the first element followed by the second element.

The first element must be Comparable.

Specified by:

compareTo in interface Comparable<A>

Parameters:

other - the other pair

Returns:

negative if this is less, zero if equal, positive if greater

Throws:

ClassCastException - if the object is not comparable

toString

The standard format is '[$first, $second]'. Spaces around the values are trimmed.

Overrides:

toString in class Object

Returns:

the pair as a string

meta

public static ObjDoublePair.Meta meta()

The meta-bean for ObjDoublePair.

Returns:

the meta-bean, not null

metaObjDoublePair

public static <R> ObjDoublePair.Meta<R> metaObjDoublePair(Class<R> cls)

The meta-bean for ObjDoublePair.

Type Parameters:

R - the bean's generic type

Parameters:

cls - the bean's generic type

Returns:

the meta-bean, not null

metaBean

public ObjDoublePair.Meta<A> metaBean()

Specified by:

metaBean in interface org.joda.beans.Bean

getFirst

public A getFirst()

Gets the first element in this pair.

Returns:

the value of the property, not null

getSecond

public double getSecond()

Gets the second element in this pair.

Returns:

the value of the property

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode
