A_Atom
A_Atom is an interface that specifies the atom-specific operations that an AvailObject must implement. It's a sub-interface of A_BasicObject, the interface that defines the behavior that all AvailObjects are required to support.

Properties
Answer the descriptive string that was supplied when this atom was created. The string didn't have to be unique within the issuingModule, but certain operations might only work if it happens to be.
Answer the message bundle associated with this atom. If the atom does not yet have a message bundle associated with it, answer nil.
Extract a Java boolean from this atom. The atom must be either the trueObject or the falseObject.
Dispatch to the descriptor.
Answer whether this atom is specially known to the Avail virtual machine.
Is the receiver an Avail byte string?
Is the receiver an Avail byte tuple?
Is the receiver an Avail extended integer?
Is the receiver an Avail function?
Dispatch to the descriptor.
Is the receiver an Avail IntTupleDescriptor? This is conservative, in that some object tuples may only contain ints but not be reported as being int tuples.
Is the receiver an Avail LongTupleDescriptor? This is conservative, in that some object tuples may only contain longs but not be reported as being long tuples.
Answer the module within which this atom was created.
Dispatch to the descriptor.
Is the receiver an Avail two-byte string?
Is the receiver an Avail unsigned byte?
Extract the ObjectLayoutVariant from an object.
Functions
Turn the receiver into an indirection to the specified object.
Answer the message bundle associated with this atom. If the atom does not yet have a message bundle associated with it, create one for that purpose and install it. The creation of the bundle is atomic, ensuring multiple fibers attempting to create the atom's bundle will agree about which bundle was created and installed in the atom.
Utility method for decomposing this object in the debugger.
Retrieve the object's {@linkplain AbstractDescriptor descriptor}.
Dispatcher helper function for routing messages to the descriptor.
Answer whether the receiver and the argument, both A_BasicObjects, are equal in value.
{@inheritDoc}
Answer whether the receiver, an object, and the argument, a byte string, are equal in value.
Answer whether the receiver, an object, and the argument, a byte tuple, are equal in value.
Answer whether the arguments, an object and a compiled code, are equal.
Answer whether the receiver equals the argument.
Answer whether the receiver equals the argument.
Determine whether the receiver is an enumeration with the given set of instances.
Answer whether the receiver, an object, and the argument, a fiber type, are equal in value.
Answer whether the receiver, an object, and the argument, a function type, are equal.
Answer whether the receiver equals the argument.
Answer whether this value equals the given list phrase type.
Answer whether the receiver equals the argument.

Extract a field from an object.
Extract a field from an object, using a one-based index into the field slots. This requires knowledge of the ObjectLayoutVariant, since the same field is at different indices in different variants.
Extract a field from an object, or answer null if it's not present.
Add or replace a field of an object.
Extract a field type from an object type.
Extract a field type from an object type, using the given field index, which is specific to an ObjectLayoutVariant.
Extract a field type from an object type, or null if it's not present.
Look up a property of this atom. Normal atoms have properties that can be set and read in this way, but specifically not enumerated by Avail code. You can see anything that you know how to look for, but everything else is thereby encapsulated.
Dispatch to the descriptor.
Answer the number of integer slots. All variable integer slots occur following the last fixed integer slot.

The receiver is marked with an IMMUTABLE descriptor, but its subobjects have not yet been made immutable. Scan them now, and do any additional fix-ups necessary for the kind of object.

The receiver is marked with a SHARED descriptor, but its subobjects have not yet been made shared. Scan them now, and do any additional fix-ups necessary for the kind of object.

Answer a name suitable for labeling a field containing this object.
Answer the number of object slots in this AvailObject. All variable object slots occur following the last fixed object slot.
Recursively print the receiver to the builder unless it is already present in the recursionMap. Printing will begin at the specified indent level, measured in horizontal tab characters.
Dispatch to the descriptor.
Answer whether the objects occupy the same memory addresses.
Dispatch to the descriptor.
Set the specified property of this atom to the specified value. Normal atoms have properties that can be set and read in this way, but specifically not enumerated by Avail code. You can see anything that you know how to look for, but everything else is thereby encapsulated.
Replace the object's {@linkplain AbstractDescriptor descriptor}.
Dispatch to the descriptor.
Replace my descriptor field with a FillerDescriptor. This blows up for most messages, catching incorrect (all, by definition) further accidental uses of this object.
Answer whether to show value-specific content in the file name for the debugger.
If the provided condition is true, synchronize with the receiver's monitor around the execution of the body function. Otherwise, run the body function without synchronization.
Follow indirections until a non-indirection is reached. Replace each indirection's target with the ultimate target.
Follow indirections until a non-indirection is reached. Replace each indirection's target with the ultimate target, even if it would cause the otherwise-forbidden immutable->mutable references. Only used during makeImmutable.
Follow indirections until a non-indirection is reached. Replace each indirection's target with the ultimate target, even if it would cause the otherwise-forbidden shared->unshared references. Only used during makeShared.
Answer the number of variable integer slots in this object. This does not include the fixed integer slots.
Answer the number of variable object slots in this AvailObject. This does not include the fixed object slots.
