Method Detail

createConfigOptions

public static Collection<ConfigOption<?>> createConfigOptions()

applyConfigEntry

public <T> void applyConfigEntry(ConfigEntry<T> entry)
                      throws InvalidConfigOptionValueException

Description copied from class: AbstractComponent

Applies a configuration option to this component. Implementations of components should use option and value of the config entry to perform an action (usually setting an internal variable to an appropriate value). Since the availability of configurators, it is optional for components to implement this method. Instead of using this method to take an action based on a configuration value, components can also use the getters defined in the components configurator. Important note: Never call this method directly. All calls are done via the ComponentManager.

Type Parameters:

T - Type of the config entry (Integer, String etc.).

Parameters:

entry - A configuration entry.

Throws:

InvalidConfigOptionValueException - This exception is thrown if the value of the config entry is not valid. For instance, a config option may only accept values, which are within intervals 0.1 to 0.3 or 0.5 to 0.8. If the value is outside of those intervals, an exception is thrown. Note that many of the common cases are already caught in the constructor of ConfigEntry (for instance for a DoubleConfigOption you can specify an interval for the value). This means that, as a component developer, you often do not need to implement further validity checks.

init

public void init()

Description copied from interface: Component

Method to be called after the component has been configured. Implementation of components can overwrite this method to perform setup and initialisation tasks for this component.
