I saw that there was an improvement in the 1.2 for Java5 enum.
As I implemented this new java5 support, i'm currently trying to
reproduce your problem.
We have
to define the following method in the enum type :
public static CompositeType fromValue(final java.lang.String value) {
for (CompositeType c: CompositeType.values()) {
if (c.value.equals(value)) {
return c;
}
}
throw new IllegalArgumentException(value);
}
Yep, as castor only gets the value string during unmarshalling, we need
this method to "map" the string value "S" to the actual enum constant.
I tried using no handler and defining this method. The method
fromValue is actually called and returned the right value but I still
have the Exception :
java.lang.IllegalArgumentException: No enum const class TaskType.S
Can you please provide the whole stacktrace, then I will have a look at
the castor code that calls the fromValue method.

Where am I wrong ?
Thanks for your help :)

What version are you using, if I may ask ?

I'm trying to unmarshal an XML field to a Java5 Enum.
I'm using a GeneralizedFieldHandler to do this.
Unfortunatly, I'm getting the following error trying to unmarshall :
java.lang.IllegalArgumentException: No enum const class TaskType.S
at java.lang.Enum.valueOf(Enum.java:192)
at TaskType.valueOf(TaskType.java:1)
...
Here is the mapping.xml :
<class name="Task">
<field name="type" type="TaskType" handler="TaskTypeHandler">
<bind-xml name="type" node="attribute" />
</field>
</class>
Here is the xml data file :
<tache type="S">
Here is Task.java :
public class Task {
private TaskType type;
public TaskType getType() {
return type;
}
public void setType(TaskType pType) {
type = pType;
}
}
Here is TaskType.java :
public enum TaskType {
SCHEDULED('S'), OPTIONAL('O'), PROVOKED('P');
private char string;
TaskType(char pChar) {
string = pChar;
}
public char getChar() {
return string;
}
}
And here is TaskTypeHandler :
public class TaskTypeHandler extends GeneralizedFieldHandler {
public TaskTypeHandler() {
super();
}
public Object convertUponGet(Object pValue) {
return null;
}
public Object convertUponSet(Object pValue) {
String tString = (String) pValue;
if (tString.equals("S")) {
return TaskType.SCHEDULED;
} else if (tString.equals("O")) {
return TaskType.OPTIONAL;
} else if (tString.equals("P")) {
return TaskType.PROVOKED;
} else {
return null;
}
}
public Class<TaskType> getFieldType() {
return TaskType.class;
}
}
It seems that Castor does not use the GeneralizedFieldHandler and uses
the default behaviour instead, that is calling TaskType.valueOf("S").
Am I something wrong ? Is there a way to bypass the default behaviour ?
Thanks,
Greg
