I have used the SortedSet instead of List and the OneToMany relation works when
I write or update but when I retrieve my composite object it gives a
ClassCastException on the TreeSet Compare. I do not know why as I have my
object as a comparator and it implements a compare method??
public boolean equals(Object obj )
| {
| boolean ret = false;
| if( obj == null ) return false;
| if( obj instanceof Counts )
| {
| Counts other = (Counts)obj;
| if( this.id == other.id &&
| this.wellNumber == other.wellNumber &&
| this.cnts == other.cnts &&
| this.milliSeconds == other.milliSeconds &&
| this.timestamp.equals(other.timestamp))
| {
| ret = true;
| }
| }
|
| return ret;
| }
|
| public int compare( Object arg0, Object arg1 )
| {
| int ret = -1;
| if( arg0 == null || arg1 == null ) return -1;
|
| if( arg0 instanceof Counts && arg1 instanceof Counts )
| {
| Counts c1 = ( Counts ) arg0;
| Counts c2 = ( Counts ) arg1;
|
| if( c1.cnts > c2.cnts ) ret = 1;
| if( c1.cnts < c2.cnts ) ret = -1;
| if( c1.equals(c2) ) ret = 0;
| }
|
| return ret;
| }
