equals

public boolean equals (Object rhs)

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

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

forIdentifier

public static MeasureUnit forIdentifier (String identifier)

Construct a MeasureUnit from a CLDR Core Unit Identifier, defined in UTS 35. (Core unit identifiers and mixed unit identifiers are supported, long unit identifiers are not.) Validates and canonicalizes the identifier. Note: dimensionless MeasureUnit is null

 MeasureUnit example = MeasureUnit::forIdentifier("furlong-per-nanosecond")
 

getAvailable

public static Set<MeasureUnit> getAvailable (String type)

For the given type, return the available units.

getAvailable

public static Set<MeasureUnit> getAvailable ()

Get all of the available units. Returned set is unmodifiable.

getAvailableTypes

public static Set<String> getAvailableTypes ()

Get all of the available units' types. Returned set is unmodifiable.

getComplexity

public MeasureUnit.Complexity getComplexity ()

Compute the complexity of the unit. See Complexity for more information.

getDimensionality

public int getDimensionality ()

Returns the dimensionality (power) of this MeasureUnit. For example, if the unit is square, then 2 is returned.

NOTE: Only works on SINGLE units. If this is a COMPOUND or MIXED unit, an exception will be thrown. For more information, see `Complexity`.

getIdentifier

public String getIdentifier ()

Get CLDR Unit Identifier for this MeasureUnit, as defined in UTS 35.

getPrefix

public MeasureUnit.MeasurePrefix getPrefix ()

Returns the current SI or binary prefix of this SINGLE unit. For example, if the unit has the prefix "kilo", then MeasurePrefix.KILO is returned.

NOTE: Only works on SINGLE units. If this is a COMPOUND or MIXED unit, an error will occur. For more information, see `Complexity`.

getSubtype

public String getSubtype ()

Get the subType, such as “foot”. May return null.

getType

public String getType ()

Get the type, such as "length". May return null.

hashCode

public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (The hashCode may or may not be implemented as some function of an object's memory address at some point in time.)

product

public MeasureUnit product (MeasureUnit other)

Computes the product of this unit with another unit. This is a way to build units from constituent parts.

The numerator and denominator are preserved through this operation.

For example, if the receiver is "kilowatt" and the argument is "hour-per-day", then the unit "kilowatt-hour-per-day" is returned.

NOTE: Only works on SINGLE and COMPOUND units. If either unit (receivee and argument) is a MIXED unit, an error will occur. For more information, see `Complexity`.

reciprocal

public MeasureUnit reciprocal ()

Computes the reciprocal of this MeasureUnit, with the numerator and denominator flipped.

For example, if the receiver is "meter-per-second", the unit "second-per-meter" is returned.

NOTE: Only works on SINGLE and COMPOUND units. If this is a MIXED unit, an error will occur. For more information, see `Complexity`.

splitToSingleUnits

public List<MeasureUnit> splitToSingleUnits ()

Returns the list of SINGLE units contained within a sequence of COMPOUND units.

Examples: - Given "meter-kilogram-per-second", three units will be returned: "meter", "kilogram", and "per-second". - Given "hour+minute+second", three units will be returned: "hour", "minute", and "second".

If this is a SINGLE unit, a list of length 1 will be returned.

toString

public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

withDimensionality

public MeasureUnit withDimensionality (int dimensionality)

Creates a MeasureUnit which is this SINGLE unit augmented with the specified dimensionality (power). For example, if dimensionality is 2, the unit will be squared.

NOTE: Only works on SINGLE units. If this is a COMPOUND or MIXED unit, an exception is thrown. For more information, see `Complexity`.

withPrefix

public MeasureUnit withPrefix (MeasureUnit.MeasurePrefix prefix)

Creates a MeasureUnit which is this SINGLE unit augmented with the specified prefix. For example, MeasurePrefix.KILO for "kilo", or MeasurePrefix.KIBI for "kibi". May return `this` if this unit already has that prefix.

There is sufficient locale data to format all standard prefixes.

NOTE: Only works on SINGLE units. If this is a COMPOUND or MIXED unit, an error will occur. For more information, see `Complexity`.
