AbstractCommonNode

public AbstractCommonNode()

Method Detail

setupManagementParameters

protected void setupManagementParameters(JPPFTaskBundle bundle)

Add management parameters to the specified bundle, before sending it back to a server.

Parameters:

bundle - the bundle to add parameters to.

getClassLoader

public AbstractJPPFClassLoader getClassLoader()

Get the main classloader for the node. This method performs a lazy initialization of the classloader.

Returns:

a ClassLoader used for loading the classes of the framework.

setClassLoader

public void setClassLoader(JPPFClassLoader cl)

Set the main classloader for the node.

Parameters:

cl - the class loader to set.

getContainer

public JPPFContainer getContainer(List<String> uuidPath)
                           throws Exception

Get a reference to the JPPF container associated with an application uuid.

Parameters:

uuidPath - the uuid path containing the key to the container.

Returns:

a JPPFContainer instance.

Throws:

Exception - if an error occurs while getting the container.

clearResourceCachesIfRequested

protected void clearResourceCachesIfRequested()

Clear the resource caches of all class loaders managed by this object.

requestResourceCacheReset

public void requestResourceCacheReset()

Request a reset of the class loaders resource caches. This method merely sets a floag, the actual reset will be performed at the next opportunity, when it is safe to do so.
