Field Detail

pm

private final ProcedureManager.ProcedureHelper pm

Helper to use the ProcedureManager without any context local lookups.

tm

private final TransactionManager.TransactionHelper tm

Helper to use the TM without any context local lookups.

pendingLoadedClasses

private java.util.Set<java.lang.Class<? extends _BaseObject_>> pendingLoadedClasses

The set of classes pending to be loaded.

objects

private java.util.Map<_BaseObject_,ObjectResource> objects

Map of legacy objects to their pseudo-resource.

pendingObjects

private java.util.Set<java.lang.Object> pendingObjects

Pending object definitions which need to be registered in the next scope.

definitions

private java.util.Deque<java.util.Set<java.lang.Object>> definitions

Variable definitions which are top-level block members.

extProgDefinitions

private java.util.Map<java.lang.Object,java.util.Set<java.lang.Object>> extProgDefinitions

Map of variable definitions which are class members.

staticReferents

private java.util.Map<java.lang.Class<? extends _BaseObject_>,java.lang.Object> staticReferents

Bogus referents associated with a static class. These are required to be able to track this as a 'persistent procedure' which will never get deleted.

referents2static

Bogus referents associated with a static class.

pendingAssigned

private java.util.Deque<java.util.Set<_BaseObject_>> pendingAssigned

The set of newly created objects which wait to be assigned. These will be deleted on the next block's scope finish, if they are not yet assigned.

pendingInitialized

private java.util.Deque<java.util.Set<_BaseObject_>> pendingInitialized

The set of newly created objects which wait to be initialized. These will be deleted when the object initialization completes.

legacyClasses

Method Detail

scopeStart

public void scopeStart(BlockDefinition block)

Provides a notification that a new scope is about to be entered.

Used to create new collections where to register the variable definitions for that block.

Specified by:

scopeStart in interface Scopeable

Parameters:

block - The explicit block definition which required this notification.

scopeFinished

public void scopeFinished()

Provides a notification that a scope is about to be exited.

All variable definitions defined in this block will have the reference counter decremented for the wrapped object.

Specified by:

scopeFinished in interface Scopeable

scopeDeleted

public void scopeDeleted()

Provides a notification that an external scope is about to be deleted.

All variables defined at this external program will have the reference counter decremented.

Specified by:

scopeDeleted in interface Scopeable

getScopeId

public ScopeId getScopeId()

Get the ScopeId for the instance.

Specified by:

getScopeId in interface Scopeable

Returns:

ScopeId.OBJECT_OPS.

decrement

private void decrement(java.util.Set<java.lang.Object> defs)

Decrement the references for all this objects.

Parameters:

defs - Scalar or array object variables.
