Method Detail

start0

public void start0()
            throws IgniteCheckedException

Overrides:

start0 in class GridCacheSharedManagerAdapter<K,V>

Throws:

IgniteCheckedException - If failed.

stop0

protected void stop0(boolean cancel)

Overrides:

stop0 in class GridCacheSharedManagerAdapter<K,V>

Parameters:

cancel - Cancel flag.

localLoader

public ClassLoader localLoader()

Returns:

Local-only class loader.

globalLoader

public ClassLoader globalLoader()

Gets distributed class loader. Note that p2pContext(UUID, IgniteUuid, String, DeploymentMode, Map) must be called from the same thread prior to using this class loader, or the loading may happen for the wrong node or context.

Returns:

Cache class loader.

onEnter

public void onEnter()

Callback on method enter.

ignoreOwnership

public boolean ignoreOwnership(boolean ignore)

Parameters:

ignore - True to ignore.

unwind

public void unwind(GridCacheContext ctx)

Undeploy all queued up closures.

Parameters:

ctx - Cache context.

onUndeploy

public void onUndeploy(ClassLoader ldr,
                       GridCacheContext<K,V> ctx)

Undeploys given class loader.

Parameters:

ldr - Class loader to undeploy.

ctx - Grid cache context.

p2pContext

public void p2pContext(UUID sndId,
                       IgniteUuid ldrId,
                       String userVer,
                       DeploymentMode mode,
                       Map<UUID,IgniteUuid> participants)
                throws IgnitePeerToPeerClassLoadingException

Parameters:

sndId - Sender node ID.

ldrId - Loader ID.

userVer - User version.

mode - Deployment mode.

participants - Node participants.

Throws:

IgnitePeerToPeerClassLoadingException

locLoaderId

public IgniteUuid locLoaderId()

Gets a local class loader id.

Returns:

Class loader uuid.

registerClasses
