Vladimir,
Price is a property of a domain object.
The whole code:
package dom.simple;
import javax.jdo.annotations.Column;
import javax.jdo.annotations.IdGeneratorStrategy;
import javax.jdo.annotations.IdentityType;
import javax.jdo.annotations.PersistenceCapable;
import javax.jdo.annotations.Persistent;
import javax.jdo.annotations.PrimaryKey;
import javax.jdo.identity.LongIdentity;
import org.apache.isis.applib.annotation.Bounded;
import org.apache.isis.applib.annotation.MemberOrder;
import org.apache.isis.applib.annotation.Title;
import org.apache.isis.applib.util.ObjectContracts;
@PersistenceCapable(identityType=IdentityType.APPLICATION,
objectIdClass=LongIdentity.class)
@Bounded
public class Category implements Comparable<Category> {
private Long id;
private String name;
private Double price;
@PrimaryKey
@Persistent(valueStrategy=IdGeneratorStrategy.NATIVE)
@Column(allowsNull="false")
@MemberOrder(sequence="1")
public Long getId() {
return this.id;
}
public void setId(Long id) {
this.id = id;
}
@Column(allowsNull="false")
@MemberOrder(sequence="2")
@Title(sequence="1")
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
@Column(allowsNull="false")
@MemberOrder(sequence="3")
public Double getPrice() {
return this.price;
}
public void setPrice(Double price) {
this.price = price;
}
public String validatePrice(Double price) {
if (price >= 0) {
return null;
} else {
return "The price must not be negative!";
}
}
@Override
public int compareTo(Category category) {
return ObjectContracts.compare(this, category, "id");
}
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((id == null) ? 0 : id.hashCode());
return result;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
Category other = (Category) obj;
if (id == null) {
if (other.id != null)
return false;
} else if (!id.equals(other.id))
return false;
return true;
}
@Override
public String toString() {
return ObjectContracts.toString(this, "id,name,price");
}
}
Thank you.
