Interface ThreadPolicy

public interface ThreadPolicy

ThreadPolicy is used by the XMLObjectManager in order to determine whether or not an XMLObject needs a new or can expose a shared instance. As a marker interface, an XMLObject implementation needn't implement ThreadPolicy if it wants to defer that control to the default behavior of the XMLObject manager.

Field Summary

static int	NEW_INSTANCE NEW_INSTANCE marks the object as being neither sharable nor poolable.
static int	POOLED_INSTANCE POOLED_INSTANCE marks the object as not being sharable, but capable of being reused in a pooled fashion.
static int	SHARED_INSTANCE SHARED_INSTANCE marks the object as capable of being shared by multiple requesting threads.

Method Summary

int	getThreadPolicy() getThreadPolicy returns the Thread policy for the object instance.

Field Detail

SHARED_INSTANCE

public static final int SHARED_INSTANCE

SHARED_INSTANCE marks the object as capable of being shared by multiple requesting threads.

POOLED_INSTANCE

public static final int POOLED_INSTANCE

POOLED_INSTANCE marks the object as not being sharable, but capable of being reused in a pooled fashion. These objects must also implement the Poolable interface. SimpleReflectable, the base class for the generic XMLObject implementations implements Poolable for you.

NEW_INSTANCE

public static final int NEW_INSTANCE

NEW_INSTANCE marks the object as being neither sharable nor poolable. All requests for this object will generate a new instance.

Method Detail

getThreadPolicy

public int getThreadPolicy()

getThreadPolicy returns the Thread policy for the object instance.
