get

public java.lang.Object get(int f)

Get value of field with index index.

This method is primarily intended for use by procedures that work on meta level of de.mguennewig.pobjects. It differs from the per field getXXX() methods in that it does not load the object's data if it is not in memory. If unsure whether the object's state has been internalized, then any call to this method must be preceded by a call to PObject.loadIfReference().

Specified by:

get in class Record

set

public final void set(int f,
                      java.lang.Object value)

Set value of field with index index.
