# JavaTXCompiler Klasse
* Konstruktor hat einen weiteren Parameter
* contextPath
* Arrays aus URLs (file-urls)
* Parameter ist Optional
* wird er gesetzt, so werden Classfiles aus den übergebenen Pfaden geladen
* die übergebenen Pfade müssen dabei die Source-Roots sein
* Beispiel:
`import de.test.Klasse;`
* `Klasse.class` liegt in `output/de/test/Klasse.class`
* dann muss contextpath auf `output` gesetzt werden
* wird der Parameter nicht übergeben, so wird der Sourceroot auf das Verzeichnis gesetzt, in dem der Compiler ausgeführt wird
* dies ist das Verhalten vom javac Compiler
* generateBytecode - Methode hat neuen Parameter: path
* wird hier null übergeben, so wird die class-File in den gleichen Ordner wie die übergebene .jav File geschrieben
* wird hier ein Pfad übergeben, so gilt dieser als output root.
* Klassen werden in outputRoot/package/name/KlassenName.class geschrieben

# Tasks
## Class files in richtigen Ordner legen ##
* Wenn Pfad übergeben, dann in Pfad + packageName
* Ohne Pfad, direkt neben die Source File legen
* wenn Source File nicht in richtigem Ordner -> Warnung ausgeben
### Stand ###
* Beinahe abgeschlossen
* TODO: Tests schreiben
## Class files einlesen
* Wenn Classpath übergeben
* Suchen in Classpath + packageName
* Müsste eigentlich UTLClassLoader automatisch machen (also packageNamen anfügen)
* Wenn nichts übergeben
* dann currentDirectory + packageName
* Für die Tests muss korrekter Classpath gesetzt werden
### Stand ###
TODO:
* es muss überall wo im Quellcode ClassLoader.getSystemClassLoader() oder ein andere Classloader verwendet wird,
* dieser ausgetauscht werden mit dem classLaoder, welcher bei der Instanzierung von JavaTXCompiler erstellt wird
## Class files mit packageNamen versehen
* In die Class file muss noch der korrekte name geschrieben werden
* kann möglicherweise ASM
* Kann ASM mittesl `cw.visit("name/mit/slashe/Getrennt"..`
* wurde bereits erledigt -> TODO: Testen
## Console Interface um Parameter -classpath und -output directory erweitern
