In the current spec section 23 (JDO reference enhancer), the mention of
jdoGetXXX, jdoSetXXX are in relation to persistent fields, and those methods
are static since its trivial to have a static method that sets a field of an
instance to a value. In terms of enhancement if the user had
int getId()
{
return id;
}
this is converted to (in general terms)
int getId()
{
... checks on StateManager as appropriate for the field
return jdoGetXXX();
}
static int jdoGetXXX(Object inst)
{
return inst.id;
}
In the case of persistent properties it is no longer trivial since the
getXXX() for example could have significant code. If the user has
int getId()
{
... complicated logic for generating a value using the various fields
return val;
}
then JPOX generates
int getId()
{
... checks on StateManager as appropriate for the field
return jdoGetXXX();
}
int jdoGetXXX()
{
... complicated logic for generating a value using the various fields
return val;
}
Consequently the jdoGetXXX, jdoSetXXX are no longer static. This has no
detrimental effect on anything, just that we could have a mention in the spec
section 23.20 to this effect.
