Hi all,
I have a series of Torque objects that I want to sort. Sometimes I want to
sort by MethodA, sometiems by MethodB. (Basically mapping onto all the
columns in my database).
Right now, I have a comparator compare method that looks like this:
public int compare( Object o1, Object o2 ) {
Daughterboard db1 = (Daughterboard) o1;
Daughterboard db2 = (Daughterboard) o2;
int sort = 0;
if ( sortMethod.equals( "ScintillationFileNumber" ) ) {
/*
* if ( db1 == null == db2 ) {
* return 0;
* }
* else if (db1 == null &&
*/
sort = Strings.clean( db1.getScintillationFileNumber()
).compareTo(
Strings.clean( db2.getScintillationFileNumber() ) );
}
else if ( sortMethod.equals( "DaughterboardId" ) ) {
sort = db1.getDaughterboardId().compareTo(
db2.getDaughterboardId() );
}
if ( sortPolarity.equals( "desc" ) ) {
sort = sort * -1;
}
return sort;
}
What I really want to do is pass in a sortMethod like
ScintillationFileNumber, and dynamically call the objects getter for that
name. If I wrap my object in a WrapDynaBean, and use that to call the data,
will is actually change the ordering of my objects? Or should I just use
the WrapDynaBean locally inside of my compare method to facilitate calling
the methods?
First time using BeanUtils, but it looks great..
Lastly, would a comparator like this be something of general interest to add
to the collections list of comparators?
