It can be instantiated in many different ways. - -```Java -//1 N. -UnitP unitP = new UnitP("1 N"); - -//1 N. -unitP = new UnitP(1.0, UnitSymbols.Newton); - -//1 N. -unitP = new UnitP(1.0, "nEwTon"); - -//1 N. -unitP = new UnitP(1.0, Units.Newton); -``` - -```UnitP``` can be seen as an abstract concept including many specific types ([full list](https://github.com/varocarbas/FlexibleParser_Java/blob/master/all_code/UnitParser/src_Public/UnitParser/UnitTypes.java)). Same-type variables can be added/subtracted. Different-type variables can be multiplied/divided, but only in case of generating a valid-type output. - -```Java -//2 N. -unitP = UnitP.Addition(new UnitP("1 N"), new UnitP(1.0, Units.Newton)); - -//1 J. -unitP = UnitP.Multiplication(new UnitP("1 N"), new UnitP("1 m")); - -//Error not triggering an exception. -//The output unit N*m^2 doesn't match any supported type. -unitP = UnitP.Multiplication -( - UnitP.Multiplication - ( - new UnitP("1 N"), new UnitP("1 m") - ), - new UnitP("1 m") -); -``` - -### Main Variable Information -```UnitP``` variables are defined according to various ```final``` fields populated at instantiation. - -```Unit``` - Corresponding [Units](https://github.com/varocarbas/FlexibleParser_Java/blob/master/all_code/UnitParser/src_Public/UnitParser/Units.java) member.
-```UnitType``` - Corresponding [UnitTypes](https://github.com/varocarbas/FlexibleParser_Java/blob/master/all_code/UnitParser/src_Public/UnitParser/UnitTypes.java) member.
-```UnitSystem``` - Corresponding [UnitSystems](https://github.com/varocarbas/FlexibleParser_Java/blob/master/all_code/UnitParser/src_Public/UnitParser/UnitSystems.java) member.
-```UnitParts``` - Defining parts of the given unit.
-```UnitPrefix``` - [Supported prefix](https://github.com/varocarbas/FlexibleParser_Java/blob/master/all_code/UnitParser/src_Public/UnitParser/Prefix.java) affecting all the unit parts.
-```BaseTenExponent``` - Base-ten exponent used when dealing with too small/big values.
-```Error``` - Variable storing all the error- and exception-related information. - -## General Rules - -All the functionalities are based upon the following ideas: -- In case of incompatibility, the first element is always preferred. -- By default, the formally-correct alternative is preferred. Some required modifications might be performed. -- By default, all the errors are managed internally. - -```Java -//1.3048. -unitP = UnitP.Addition(new UnitP("1 m"), new UnitP("1 ft")); - -//Error not triggering an exception. -//The parser expects "km" or a full-name-based version like "KiLom". -unitP = new UnitP("1 Km"); - -//999999.9999999001*10^19 YSt. -unitP = UnitP.Multiplication -( - 999999999999999999999999999999999999.9, - new UnitP("9999999999999 St") -); -``` - -## Unit String Parsing Format - -The unit string parsing part is quite flexible, but there are some basic rules. -- String multi-part units are expected to be exclusively formed by units, multiplication/division signs and integer exponents. -- Only one division sign is expected. The parser understands that all what lies before/after it is the numerator/denominator. - -```Java -//1 W. -unitP = new UnitP("1 J*J/s*J2*J-1*s*s-1"); - -//Error not triggering an exception. -//The parser understands "J*J/(s*J2*s*J*s)", what doesn't represent a supported type. -unitP = new UnitP("1 J*J/(s*J2*s)*J*s"); -``` - -## Numeric Support -Formally, only the ```double``` type is supported. Practically, ```UnitP``` variables implement a mixed system delivering beyond-```double```-range support. - -```Java -//7.891011 ft. -unitP = UnitP.Multiplication(new UnitP("1 ft"), 7.891011); - -//1.213141516 Gs. -unitP = UnitP.Multiplication(new UnitP("1 s"), 1213141516.0); - -//0.0003094346047382587*10^-752 ym. -unitP = UnitP.Division -( - UnitP.Division - ( - UnitP.Division - ( - UnitP.Multiplication - ( - 0.0000000000000000000000000000000000000000000000001, - new UnitP(0.000000000000000000001, "ym2") - ), - new UnitP("999999999999999999999 Ym") - ), - Double.MAX_VALUE - ), - Double.MAX_VALUE -); -``` - -## Further Code Samples -The [test application](https://github.com/varocarbas/FlexibleParser_Java/blob/master/all_code/Test/src/Parts/UnitParser.java) includes a relevant number of descriptive code samples. - -## Authorship & Copyright - -I, Alvaro Carballo Garcia (varocarbas), am the sole author of each single bit of this code. - -Equivalently to what happens with all my other online contributions, this code can be considered public domain.
