Member Function Documentation
| io::version_id Trial::class_version_id | ( | ) | const [virtual] |
Returns a serialization version id for the class. The default implementation returns zero. Classes should override this when they make a change that requires a change to their serialization protocol. Overriding versions of this function should follow the convention that a higher id refers to a later version of the class. Implementations of io::reader and io::writer will provide a way for a class to store and retrieve the serialization version of an object.
Reimplemented from io::serializable.
| void Trial::read_from | ( | io::reader & | reader | ) | [virtual] |
Subclasses implement this method to save the object's state via the generic interface provided by io::reader. Parsing the format of the input is handled by the io::reader, so implementors of read_from() of don't need to deal with formatting.
Implements io::serializable.
Definition at line 232 of file trial.cc.
References io::reader::ensure_version_id(), and SRC_POS.
| void Trial::write_to | ( | io::writer & | writer | ) | const [virtual] |
Subclasses implement this method to restore the object's state via the generic interface provided by io::writer. Formatting the output is handled by the io::writer, so implementors of write_to() of don't need to deal with formatting.
Implements io::serializable.

| fstring Trial::stdInfo | ( | ) | const |
Returns a standard set of descriptive information.
This is here mostly for legacy reasons; this function used to be the implementation of vxInfo().
Definition at line 430 of file trial.cc.

| void Trial::setInfo | ( | rutz::fstring | info | ) |
| void Element::vxEndTrialHook | ( | ) | [virtual, inherited] |
Hook function that gets called each time a leaf (i.e., trial) completes.
Shouldn't be used for substantive action, but just for bookkeeping such as timekeeping, autosaving, etc. Default version is a no-op.
Reimplemented in Block, and ExptDriver.
Definition at line 41 of file element.cc.
Referenced by Block::vxEndTrialHook().
| nub::uid nub::object::id | ( | ) | const throw () [inherited] |
| rutz::fstring nub::object::real_typename | ( | ) | const [inherited] |
Returns the typename of the full object.
The result is a demangled version of typeid(*this).name(), which should very closely resemble the way the object was declared in source code.
Definition at line 67 of file object.cc.
References rutz::demangled_name().
Referenced by nub::object::obj_typename().
| rutz::fstring nub::object::obj_typename | ( | ) | const [virtual, inherited] |
Returns the (apparent) typename of the full object.
The default implementation just returns real_typename(). However, certain kinds of objects -- e.g., proxy objects -- might usefully choose to have obj_typename() return something besides the real_typename(), in order to masquerade as a different type of object.
Reimplemented in io::proxy< C >, io::const_proxy< C >, MtxObj, and TrialMemFuncEvent.

| void * nub::ref_counted::operator new | ( | size_t | bytes | ) | [inherited] |
Class-specific operator new; protected to ensure that clients use factory functions.
Definition at line 157 of file refcounted.cc.
| void nub::ref_counted::operator delete | ( | void * | space, | |
| size_t | bytes | |||
| ) | [inherited] |
Class-specific operator delete; private since deletion should only happen in ref_counted::decr_ref_count.
Definition at line 163 of file refcounted.cc.
| void nub::ref_counted::incr_ref_count | ( | ) | const throw () [inherited] |
Increment the object's reference count.
This operation (on the strong reference count) is not permitted if the object is unshareable. Unshareable objects can only have their weak reference counts manipulated.
Definition at line 207 of file refcounted.cc.
References nub::ref_counts::acquire_strong().
Referenced by GxEmptyNode::make().
| void nub::ref_counted::decr_ref_count | ( | ) | const throw () [inherited] |
Decrement the object's reference count.
If this causes the reference count to fall to zero or below, the pointee and the pointer will be destroyed by a call to 'delete this'. This operation (on the strong reference count) is not permitted if the object is unshareable. Unshareable objects can only have their weak reference counts manipulated.
Definition at line 212 of file refcounted.cc.
References nub::ref_counts::release_strong().
| void nub::ref_counted::decr_ref_count_no_delete | ( | ) | const throw () [inherited] |
Decrement the object's reference count, but don't delete it.
Unlike decr_ref_count(), the object will NOT be delete'd if the reference count falls to zero. This operation (on the strong reference count) is not permitted if the object is unshareable. Unshareable objects can only have their weak reference counts manipulated.
Definition at line 221 of file refcounted.cc.
References nub::ref_counts::release_strong_no_delete().
| bool nub::ref_counted::is_shared | ( | ) | const throw () [inherited] |
Returns true if no external client has sole ownership of the object.
This may occur if either (1) the reference count is greater than one, or (2) the object is_not_shareable(), meaning that the object itself is the only "owner".

Referenced by nub::ref_counted::is_unshared().
| bool nub::ref_counted::is_unshared | ( | ) | const throw () [inherited] |
Returns true if there is a sole external owner of the object.
This occurs if the reference count is one or less and the object is shareable.
Definition at line 236 of file refcounted.cc.
References nub::ref_counted::is_shared().
| bool nub::ref_counted::is_not_shareable | ( | ) | const throw () [inherited] |
Returns true if the object is not shareable for any reason. This could be because its lifespan is volatile (such as objects representing on-screen windows that can be dismissed by the user). The default is for objects to be shareable; objects can declare themselves as unshareable by calling mark_as_volatile().

| const Field & FieldContainer::field | ( | const rutz::fstring & | name | ) | const [inherited] |
Lookup the Field for a given name.
An exception will be thrown if no such Field is found.
