orc.runtime.regions
Class Region

java.lang.Object
  orc.runtime.regions.Region

Direct Known Subclasses:

Execution, GroupRegion, SemiRegion

public abstract class Region
extends java.lang.Object

Regions are used to track when some (sub-)computation terminates.

Currently the region methods must be synchronized, because tokens can be killed by independent threads (such as site calls in progress), triggering an update on the region. Maybe we should have a separate queue deal with dead tokens so this isn't necessary.

public void remove(Region r,
                   Token closer)

close

public final void close(TokenTracer.StoreTrace store,
                        Token closer)

Used when tracing, to both close the region and trace the "choking" of all tokens within the region. If you're not tracing, it's more efficient to call close(Token).

Parameters:

store - The TokenTracer.StoreTrace which triggered the closing.

putContainedTokens

public void putContainedTokens(java.util.Set<Token> acc)
