 SessionFactory factory)

Method Details

getId

public UUID getId()

getStereotype

public Capabilities getStereotype()

reserve

public void reserve()

tryReserve

public boolean tryReserve(Capabilities capabilities)

Atomically attempts to reserve this slot if it's available and matches the given capabilities. This method is thread-safe and eliminates the need for external synchronization.

Parameters:

capabilities - the capabilities to test against this slot's stereotype

Returns:

true if the slot was successfully reserved, false if already reserved or capabilities don't match

release

public void release()

isAvailable

public boolean isAvailable()

getSession

public @Nullable ActiveSession getSession()

stop

public void stop()

stop

public void stop(SessionClosedReason reason)

stop

public void stop(SessionClosedReason reason,
 @Nullable NodeId nodeId,
 @Nullable URI nodeUri)

Stops the session with full context for sidecar services.

Parameters:

reason - the reason for closing the session

nodeId - the ID of the node where the session was running (may be null for backward compatibility)

nodeUri - the URI of the node where the session was running (may be null for backward compatibility)
