Interface MergingConfiguration

All Superinterfaces:

Configuration, java.io.Serializable

All Known Subinterfaces:

MergingActivityConfiguration

public interface MergingConfiguration
extends Configuration

This class merges several configurations to one configuration. All configurations are managed in a list. When retrieving a configuration value, the list is iterated and the first non-null value is returned.
String values may contain variables that are replaced appropriately.

Method Detail

getConfigurations

java.util.List<? extends Configuration> getConfigurations()

Gets a copy of the list of all configurations that are merged by this MergingConfiguration. Prior configurations override later ones.

Returns:

A list of all configurations that are merged by this MergingConfiguration.

addFirst

void addFirst(Configuration configuration)

Adds the designated configuration as the first configuration that overrides the other configurations.

Parameters:

configuration - The configuration to override the other configurations in this MergingConfiguration. This must not be null.

addLast

void addLast(Configuration configuration)

Adds the designated configuration as the last configuration that is overridden by all other configurations.

Parameters:

configuration - The configuration that is overridden by all other configurations in this MergingConfiguration. This must not be null.

getMergedConfiguration

Configuration getMergedConfiguration()

Gets one configuration containing the merged values, that is the list of configurations is merged to a single configuration. This allows for better performance than this MergingConfiguration.
Variables in strings are replaced in the merged configuration.

Returns:

One configuration containing the merged values of all configurations of this MergingConfiguration.
