I am trying to create a subclass of an abstract class in bytebuddy and want to override the constructor with my own function. I can not make it work with defineConstructor.
Superclass:
public abstract class AbstractDMTable {
protected HashMap<String, DMEntry<?>> parameterMap;
public DMEntry<?> getParameter(String paramName) {
if (parameterMap.containsKey(paramName))
return parameterMap.get(paramName);
return null;
}...
Subclass:
public class DMTable_DEBUGOUT extends AbstractDMTable {
/**
* Table entry
* prints the value of the specified parameter
*/
public DMEntry<DMEntry<?>> DEBUG_PARAM;
/**
* Table entry
* execution interval of the step handler (s)
*/
public DMEntry<Double> EXEC_INTERVAL;
/**
* Table entry
* active / not active status of this subsystem
*/
public DMEntry<Boolean> IS_ACTIVE;
/**
* Standard constructor. Creates a new table and initializes all entry fields with all entry values set to {@code null}
*/
public DMTable_DEBUGOUT() {
super();
DEBUG_PARAM = new DMEntry<>();
parameterMap.put("DEBUG_PARAM", DEBUG_PARAM);
EXEC_INTERVAL = new DMEntry<>();
parameterMap.put("EXEC_INTERVAL", EXEC_INTERVAL);
IS_ACTIVE = new DMEntry<>();
parameterMap.put("IS_ACTIVE", IS_ACTIVE);
}
}
My ByteBuddy:
DynamicType.Builder<? extends AbstractDMTable> subsystem = new ByteBuddy().subclass(AbstractDMTable.class)
.name("DMTable_" + name).defineConstructor(Collections.<Class<AbstractDMTable>> emptyList(), Visibility.PUBLIC);
for (Entry<String, Pair<String, String>> p : t.getValue().entrySet()) {
subsystem.defineField(p.getKey(), this.createSubSystemEntry(p).getClass(), Visibility.PUBLIC);
}
// subsystem.defineConstructor(Arrays.<Class<AbstractDMTable>>
// asList(int.class), Visibility.PUBLIC);
return subsystem.make().load(getClass().getClassLoader(), ClassLoadingStrategy.Default.WRAPPER).getLoaded();
The Error:
defineConstructor(ModifierContributor.ForMethod...) in the type
DynamicType.Builder<AbstractDMTable> is not applicable for the
arguments (List<Class<?>>, Visibility) DynamicDatabaseGenerator.java
line 66 Java Problem
