Maybe my java-files didn't get throug in my first mail :)
I will just paste them here.
My intent with my mail was to tell people that I have made this
NamedPropertySelectionModel that I think alot of people would be glad
to use. I would also want to know if there is something similar in the
framwork (or planned to be implemented) that I should use instead.
here are the files from my first mail:
package net.keso.ted.peng;
/************ INamedProperty.java ***********/
public interface INamedProperty {
public String getPropertyName();
}
/************ NamedPropertySelectionModel.java ***********/
package net.keso.ted.peng;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.Collection;
import java.util.List;
import org.apache.tapestry.form.IPropertySelectionModel;
public class NamedPropertySelectionModel implements IPropertySelectionModel {
private List<INamedProperty> _list;
/**
* Build an empty named property selection model.
*/
public NamedPropertySelectionModel() {
this(Arrays.asList(new INamedProperty[0]));
}
/**
* Build a named property selection model.
* @param list The list
*/
public NamedPropertySelectionModel(List<INamedProperty> list) {
_list = list;
}
/**
* Build a named property selection model.
* @param c Collection
*/
public NamedPropertySelectionModel(Collection<? extends INamedProperty> c) {
_list = new ArrayList<INamedProperty>(c);
}
/**
* Get the number of options.
* @return option count
*/
public int getOptionCount() { return _list.size(); }
/**
* Get the option at index.
* @param index Index
* @return object Object at index
*/
public Object getOption(int index) {
return _list.get(index);
}
/**
* Get the label at index.
* @param index Index
* @return label Label at index
*/
public String getLabel(int index) {
INamedProperty prop = _list.get(index);
return prop.getPropertyName();
}
/**
* Get the value at index.
* @param index Index
* @return value Value at index
*/
public String getValue(int index) {
return String.valueOf(index);
}
/**
* Translate value to object.
* @param value Value
* @return object Object from value
*/
public Object translateValue(String value) {
return getOption(Integer.parseInt(value));
}
}
