Class EqualsUtil

java.lang.Object
com.webmethods.caf.wsclient.util.EqualsUtil
public final class EqualsUtil extends Object
Collected methods which allow easy implementation of equals. Example use case in a class called Car: 
public boolean equals(Object that){
  if ( this == that ) return true;
  if ( !(that instanceof Car) ) return false;
  Car thatCar = (Car)that;
  return
    EqualsUtil.areEqual(this.fName, that.fName) &&
    EqualsUtil.areEqual(this.fNumDoors, that.fNumDoors) &&
    EqualsUtil.areEqual(this.fGasMileage, that.fGasMileage) &&
    EqualsUtil.areEqual(this.fColor, that.fColor) &&
    Arrays.equals(this.fMaintenanceChecks, that.fMaintenanceChecks); //array!
}
Arrays are not handled by this class. This is because the Arrays.equals methods should be used for array fields.
