Class Realtime.ObjectSpace

java.lang.Object
  javolution.realtime.Realtime.ObjectSpace

Enclosing interface:

Realtime

public static class Realtime.ObjectSpace
extends java.lang.Object

This class represents an object space which determinates when object recycling occurs.

• HEAP: Associated memory recycled through garbage collection when the object is not reachable (default).
• STACK: Recycled when the current thread exits the scope of the PoolContext where the object has been "factory produced".
• HOLD: Not recycled, moved back to its original space when internal preserve count drops to zero.
Applications may create their own object space. Here are few examples of possible spaces with their defining characteristics.
• AGING: Recycling done when the objects are old enough.
  Constraint: It assumes that old objects become obsolete and are not referenced anymore.
• FLIP: Recycling done when the object space is flipped.
  Constraint: Objects from previous period (before flip) are discarded.

Field Summary

static Realtime.ObjectSpace	HEAP Identifies the heap space; objects are accessible by all; they are indirectly recycled through garbage collection (default space).
static Realtime.ObjectSpace	HOLD Identifies the hold space; objects are accessible by all; they are moved back to their original space when not held anymore (internal counter).
static Realtime.ObjectSpace	OUTER Identifies the current outer object space; it is the object space after exiting the current PoolContext (typically the HEAP or another STACK space).
static Realtime.ObjectSpace	STACK Identifies the stack space; objects are accessible by the current thread only; they are recycled when the current thread exits the PoolContext scope where the object has been factory produced.

Field Detail

HEAP

public static final Realtime.ObjectSpace HEAP

Identifies the heap space; objects are accessible by all; they are indirectly recycled through garbage collection (default space).

STACK

public static final Realtime.ObjectSpace STACK

Identifies the stack space; objects are accessible by the current thread only; they are recycled when the current thread exits the PoolContext scope where the object has been factory produced.

OUTER

public static final Realtime.ObjectSpace OUTER

Identifies the current outer object space; it is the object space after exiting the current PoolContext (typically the HEAP or another STACK space).

HOLD

public static final Realtime.ObjectSpace HOLD

Identifies the hold space; objects are accessible by all; they are moved back to their original space when not held anymore (internal counter).
