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.

Parameters:

public final String getProperty(String name)

Get an app property.

Threading:

This method is safe for concurrent access by multiple threads.

setProperties

public final SrvConfigAppDescriptor setProperties(Properties props)

Set a set of app properties.

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.
