+# 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

+Generics können nicht ignoriert werden.
+Folgender Fall ist Typisierbar:

+\begin{program}
+<T> T m1(T x){

+
+m2(x){

+Beim weglassen des Generics T wäre es aber nicht mehr möglich.
+Dann erhält jeder Constraint, welcher in Verbindung mit der Methode m1 steht
