Class SIUnitTypeRelations

de.monticore.types3.util.SIUnitTypeRelations

public class SIUnitTypeRelations
extends java.lang.Object

calculates, e.g., the product or inverse of SymTypeOfSIUnits one may assume this functionality ought to be in SymTypeOfSIUnit, however, it relies on other functionality in SymTypeRelations, and the behaviour of SymTypeClasses should not be dependent on the current type system (or one would need to pass the SymTypeRelations to the SymTypes) delegate of SymTypeRelations

delegate

baseUnitStrings

protected static final java.util.List<java.lang.String> baseUnitStrings

List of the base units (without prefixes)

conversionTable

protected static final java.util.Map<java.lang.String,java.util.List<SIUnitBasic>> conversionTable

Method Detail

isOfDimensionOne

public static boolean isOfDimensionOne(SymTypeOfSIUnit siUnit)

whether this is of dimension 1, s. DIN EN ISO 80000-1:2023-08 (chap. 5) e.g.: m/m,º

_isOfDimensionOne

protected boolean _isOfDimensionOne(SymTypeOfSIUnit siUnit)

internal_normalize

public static SymTypeOfSIUnit internal_normalize(SymTypeOfSIUnit siUnit)

returns a SymTypeOfSIUnit only consisting of the seven SI base units (s, m, kg, A, K, mol, cd) any prefixes are removed (except "k" of kg) Additionally, only one of each base unit exists in the SymType, e.g., kg^2*m*kg -> kg^3*m and every exponent is positive, e.g., kg^-2*m^0*s/K^-2 -> s*K^2/kg^2

this is implemented here (instead of the normalize visitor), as it requires a lot of domain-specific knowledge / calculations.

_normalize

protected SymTypeOfSIUnit _normalize(SymTypeOfSIUnit siUnit)

convertToSIBaseUnits

protected static SymTypeOfSIUnit convertToSIBaseUnits(SymTypeOfSIUnit siUnit)

returns a SymTypeOfSIUnit only consisting of the seven SI base units (s, m, kg, A, K, mol, cd) any prefixes are removed (except "k" of kg)
