[SOLVED]EntrySet is not supported by Example

wujiang

Hi there

I have a project for add a operator to RM, Recently, I use the iterator for deal with 'example'. like:

public Reader(Example example) {
this.example = example.entrySet().iterator();
}

but once I execute my operator, a report of bug will be shown:

SEVERE: Process failed: operator cannot be executed (EntrySet is not supported by Example.). Check the log messages...
java.lang.UnsupportedOperationException: EntrySet is not supported by Example.

but, example is a type of Map ?

Could you help me?

Thanks a lot.

Hi,

as you can see in the Example.java class, not every operation from the parent class is supported. You can iterate over all values from an example via

for (Attribute att : example.getAttributes()) {
System.out.println(example.getValue(att));
}

Regards,
Marco
