Constructor Detail

SiUnit

SiUnit(int dimension)

Primary constructor to create a SiUnit.

Parameters:

dimension - which dimension (according to the values defined below).

Method Detail

getDimensions

public Dimensions getDimensions()

Method to return the dimensions of this Measurable.

Returns:

the Dimensions.

getScale

public Rational getScale()

Method to return the scale of this Measurable.

Returns:

the scale.

getOffset

public Rational getOffset()

Method to return the offset of this Measurable.

Returns:

the offset, usually $0.

isInSystem

public boolean isInSystem(int systemIndex)

Method to determine if this Measurable is in a certain system of units.

Overrides:

isInSystem in class BaseUnit

Parameters:

systemIndex - the index of the units system.

Returns:
