Phil,
Unfortunately, the code is a proprietary part of our system and
considered confidential. I feel like a hypocrite for requesting example
code and then not being willing (well, able) to give it up myself. I
hope you can understand.
I can tell you that we generate a class for each Field and that class
has two methods. If it was written in java rather than bcel, it would
look as follows.
public class SomeClassName_someFieldName extends FieldAccessor
{
public void setValue(Object target, Object value)
{
((SomeClassName)target).someFieldName = (SomeFieldClass)value;
}
public Object getValue(Object target)
{
return ((SomeClassName)target).someFieldName;
}
[There's more to it than this since you have to do something special for
primitive type, but this should give you the basic idea.]
We then access it as follows:
SomeClassName target = new SomeClassName();
SomeClassName_someFieldName accessor = new
SomeClassName_someFieldName();
accessor.setValue(target, someValue);
SomeFieldClass fieldValue = (SomeFieldClass)accessor.value(target);
I hope this helps!
Charles.
