For data sets with header, each line will be converted into ``Map<String, String>`` with
column names are used as keys. Thus the entire data set can be converted into ``List<Map<String, String>``.
For the example above our parser will yield
```
[
{
atomicNumber: 1,
symbol: H,
name: Hydrogen,
standardState: gas,
groupBlock: nonmetal,
yearDiscovered: 1766
}.
{
atomicNumber: 2,
symbol: He,
name: Helium,
standardState: gas,
groupBlock: noble gas,
yearDiscovered: 1868
}
]
```
### Evaluation
Beside functional correctness this assignment is focused on object-oriented design and understanding how IO works in java.
This means that the way you structure your program will be an important part of its evaluation.
On the other hand the given set of tests is not trying to provide an elaborate test coverage and **incorrect behaviour in corner-cases should not have a large impact on the evaluation**.
*Note that all this is at your seminar teacher's discretion.*
The maximum number of points for this assignment is **15**.
-**11 points** for passing the tests (attached tests do not guarantee a 100% correctness).
-**4 points** for correct and clean implementation (evaluated by your class teacher).
### Preconditions
To successfully implement this assignment you need to know the following
1. Understadning of OOP in Java
2. Working with collections
3. Basic knowledge of Generic types
4. Understanding of IO in java (pakcages ``java.io`` and ``java.nio``)
### Project structure
The structure of project provided as a base for your implementation should meet the following criteria.
1. Package ```cz.muni.fi.pb162.hw03.csv``` contains classes and interfaces provided as part of the assignment.
-**Do not modify or add any classes or subpackages into this package.**
2. Package ```cz.muni.fi.pb162.hw03.csv.impl``` should contain your implementation.
-**Anything outside this package will be ignored during evaluation.**
### Names in this document
Unless fully classified name is provided, all class names are relative to package ```cz.muni.fi.pb162.hw03.csv``` or ```cz.muni.fi.pb162.hw03.csv.impl``` for classes implemented as part of your solution.
### Compiling the project
The project can be compiled and packaged in the same way you already know
```bash
$ mvn clean install
```
The only difference is, that unlike with seminar project, this time checks for missing documentation and style violation will produce an error.
You can temporarily disable this behavior when running this command.
```bash
$ mvn clean install-Dcheckstyle.fail=false
```
You can consult your seminar teacher to help you set the ```checkstyle.fail``` property in your IDE (or just google it).
### Submitting the assignment
The procedure to submit your solution may differ based on your seminar group. However generally it should be OK to submit ```target/homework02-2021-1.0-SNAPSHOT-sources.jar``` to the homework vault.
## Implementation notes
Generally speaking there are no mandatory requirements on the structure of your code other than what is enforced by provided interfaces
* Provided tests should give you a good idea about the inteded use of this library
* Think about how IO streams are structured in java, ``CsvReader`` is essentially another layer.
