The quantity data type is an abstract generalization for all data types (1) whose value set has an order relation (less-or-equal) and (2) where difference is defined in all of the data type's totally ordered value subsets. The quantity type abstraction is needed in defining certain other types, such as the interval and the probability distribution.

Method Detail

lessOrEqual

BL lessOrEqual(QTY x)

A predicate expressing an order relation that is reflexive, asymmetric and transitive, between this quantity and another quantity. The relation is defined on any totally ordered partition of the quantity data type. A totally ordered partition is a subset of the data types's defined values where all elements have a defined order (e.g., the integer and real numbers are totally ordered.) By contrast, a partially ordered set is a set where some, but not all pairs of elements are comparable through the order relation (e.g., a tree structure or the set of physical quantities is a partially ordered set.) Two data values x and y of an ordered type are comparable (x.compares(y)) if the less-or-equal relation holds in either way (x ? y or y ? x). A partial order relation generates totally ordered subsets whose union is the entire set (e.g., the set of all length is a totally ordered subset of the set of all physical quantities.)

Returns:

True if value passed is less or equal

compares

BL compares(QTY x)

A predicate indicating if this value and the operand can be compared as to which is greater than the other. Two quantities are comparable if they are both elements of a common totally ordered partition of their data types' value space. The definition is based on QTY.lessOrEqual.

Returns:

true if given object can be compared with current object

diffType

TYPE diffType()

The type of the difference between 2 values of a specific QTY data type.

Returns:

type of difference

minus

QTY minus(QTY x)

A quantity expressing the "distance" of this quantity from the operand quantity, that must be comparable. The data type of the difference quantity is related to the operand quantities but need not be the same.

Returns:

difference of this quantity from the operand quantity

plus

QTY plus(QTY x)

The sum of this quantity and its operand. The operand must be of a data type that can express the difference between two values of this quantity's data type.

Returns:

sum of this quantity and its operand

isZero

BL isZero()

The neutral element in the difference and addition operations, i.e., if a quantity is zero, addition to, or subtraction from any other comparable quantity will result in that other quantity.

Returns:

if quantity is zero

lessThan

BL lessThan(QTY x)

A predicate expressing an order relation that is asymmetric and transitive, between this quantity and another quantity. The ordering is the same as QTY.lessOrEqual, but irreflexive.

Returns:

True if passed Quantity is less than current

greaterOrEqual

BL greaterOrEqual(QTY x)

A predicate expressing an order relation that is reflexive, asymmetric and transitive, between this quantity and another quantity. This is the inverse order of QTY.lessOrEqual.

Returns:

True if passed Quantity is greater or equal than current

greaterThan

BL greaterThan(QTY x)

A predicate expressing an order relation that is asymmetric and transitive, between this quantity and another quantity. This is the invese of QTY.lessThan.

Returns:

True if passed Quantity is greater than current
