java.lang.Object
  kortsoft.kmx.deployer.KmxDaemon

All Implemented Interfaces:

KmxDaemonInterface, KmxDaemonMBean

public class KmxDaemon
extends java.lang.Object
implements KmxDaemonInterface, KmxDaemonMBean

KmxDameon responsability is to check modified or new components to be deployed. It must be assigned the directories to check (in the future it could check other sources) with the method setWatchDirectories(List). Takes the modified or new components and selects a Deployer taken within:

• Extra Deployers (based on a FilenameFilter)

These Extra deployers must be assigned with the method addExtraDeployer(Class,FilenameFilter).

Method Detail

checkDirectoryChanges

protected java.util.List<java.io.File> checkDirectoryChanges(java.io.File directory,
                                                             java.util.Map<java.io.File,java.lang.Long> lastLoadings)

Check modifications in a directory. New files and modified files/directories are returned as a List . It is passed a Map with the timestamp of the file/directory last load, so it can be compared with the modification timestamp.

Parameters:

directory -

lastLoadings -

Returns:

loadDeployer

protected Deployer loadDeployer(java.io.File element)
                         throws DeployerCreationException

Loads an instance of a Deployer suitable for the specified file. First seek for the deployer class in a caché if it has been loaded previously (now it is a reload). If it doesn't find the file in the caché, look for a deployer for that type of file (both in advanced Deployer and in default deployes).

Parameters:

jarFile -

Returns:

Throws:

DeployerCreationException
