This directory contains an embryo of an example of how to
generate and compile a labcomm endpoint on the fly.
-NB! There is currently no connection between the files StaticPart.java, DynamicPart.java, and
-TestLabCommCompiler.java
+NB! There is currently no connection to the StaticPart.java
+
+the runme.sh script builds and runs the TestLabCommGen, which illustrates the
+on-the-fly compilation to RAM, reading the labcomm declarations and handlers from file
+
+The handlers declaration (in handlers.txt) is experimental, and has the following format:
+
+<sample name>:handler(<data type> <variable name>) {
+ <handler method code>
+}###
+
+where the end marker (}###) is a kludge to avoid having to parse the method body while still allowing
+it to contain blocks. Thus, having the sequence "}###" in the method body breaks this. Caveat hacker!
+
+An example handlers declaration:
+
+foo:handler(foo value) {
+ System.out.println("foo handler from handlers.txt");
+ System.out.println(value.x);
+ System.out.println(value.y);
+ System.out.println(value.z);
+ for(int i=0; i<value.x; i++){
+ System.out.print("."+(value.x-i));
+ }
+ System.out.println();
+}###
+bar:handler(int value) {
+ System.out.println(value);
+}###
-the runme.sh script builds and runs the TestLabCommCompiler, which illustrates the
-on-the-fly compilation to RAM, reading the labcomm declarations from file but with the
-handlers hard coded in the test program.
