Threading:

This method is safe for concurrent access by multiple threads.

setMainClass

public final SrvConfigAppDescriptor setMainClass(String mainClass)

Set the name of application's main class.

Returns:

Returns this object for invocation chaining.

Threading:

This method is safe for concurrent access by multiple threads.

getProperties

public final Properties getProperties()

Get the app properties

Threading:

This method is safe for concurrent access by multiple threads.
