ScanningAppProvider

protected ScanningAppProvider()

ScanningAppProvider

protected ScanningAppProvider(java.io.FilenameFilter filter)

Method Detail

setFilenameFilter

protected void setFilenameFilter(java.io.FilenameFilter filter)

getDeployedApps

protected java.util.Map<java.lang.String,App> getDeployedApps()

Returns:

The index of currently deployed applications.

createApp

protected App createApp(java.lang.String filename)

Called by the Scanner.DiscreteListener to create a new App object. Isolated in a method so that it is possible to override the default App object for specialized implementations of the AppProvider.

Parameters:

filename - The file that is the context.xml. It is resolved by Resource.newResource(String)

Returns:

The App object for this particular context definition file.

doStop

protected void doStop()
               throws java.lang.Exception

Overrides:

doStop in class AbstractLifeCycle

Throws:

java.lang.Exception

exists
