Method Detail

getConfiguration

public static <T extends PluginConfiguration> T getConfiguration(java.lang.Class<T> configurationInterface,
                                                                 PluginConfiguration pluginConfiguration)

Returns an instance of the provided configuration interface that attempts to provide a parsed view of the raw configuration.

The relations to the raw configuration properties are determined by reflection on the provided Java interface.

The rules are the following - the provided interface must extend the PluginConfiguration and define getters in the forms '<type> getX()' or 'boolean isY()' - the returned values are constructed from type defined in the provided configuration interface by calling the valueOf(String) method (eg. String.valueOf(String)) - String getX() attempts to parse the value of the raw configuration property defined by x=value using the String.valueOf(String) method - if a property is multivalued then the returned type of the method defined in the provided configuration interface must be of type java.util.Collection and the type contained type contained in that collection must be defined using the annotation ConfigurationProperty (String is the default type).

Beware that parsing the raw configuration can throw undeclared exceptions.

Type Parameters:

T - the type of the configuration interface that attempts to provide the parsed configuration.

Parameters:

configurationInterface - the interface that defines the types and the names of the parsed configuration properties.

pluginConfiguration - the configuration providing the raw properties.

Returns:

an instance of the provided configuration interface that attempts to provide a parsed view of the raw configuration.
