Method Detail

of

public static LongDoublePair of(long first,
                                double second)

Obtains an instance from a long and a double.

Parameters:

first - the first element

second - the second element

Returns:

a pair formed from the two parameters

ofPair

public static LongDoublePair ofPair(Pair<Long,Double> pair)

Obtains an instance from a Pair.

Parameters:

pair - the pair to convert

Returns:

a pair formed by extracting values from the pair

parse

public static LongDoublePair parse(String pairStr)

Parses a LongDoublePair from the standard string format.

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

Parameters:

pairStr - the text to parse

Returns:

the parsed pair

Throws:

IllegalArgumentException - if the pair cannot be parsed

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<Long,Double> toPair()

Converts this pair to an object-based Pair.

Returns:

the object-based pair

compareTo

public int compareTo(LongDoublePair other)

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

This compares the first elements, then the second elements.

Specified by:

compareTo in interface Comparable<LongDoublePair>

Parameters:

other - the other pair

Returns:

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

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Gets the pair using a standard string format.

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 LongDoublePair.Meta meta()

The meta-bean for LongDoublePair.

Returns:

the meta-bean, not null

metaBean

public LongDoublePair.Meta metaBean()

Specified by:

metaBean in interface org.joda.beans.Bean

getFirst

public long getFirst()

Gets the first element in this pair.

Returns:

the value of the property

getSecond

public double getSecond()

Gets the second element in this pair.

Returns:

the value of the property
