Class PolyglotProperties.PolyglotPropertiesFactory

java.lang.Object

org.refcodes.configuration.PolyglotProperties.PolyglotPropertiesFactory

All Implemented Interfaces:

ResourcePropertiesFactory, org.refcodes.mixin.FilenameExtensionsAccessor

Enclosing class:

PolyglotProperties

public static class PolyglotProperties.PolyglotPropertiesFactory
extends Object
implements ResourcePropertiesFactory

The PolyglotProperties.PolyglotPropertiesFactory is a meta factory using a collection of ResourcePropertiesFactory instances to deliver ResourceProperties instances. In case a properties file for a filename was not found, then the according factories filename extension (FilenameExtensionsAccessor.getFilenameExtensions()) is append to the filename and probing is repeated. Any factory method such as toProperties(Map), toProperties(Object), toProperties(Properties) or toProperties(PropertiesBuilder) will return ResourceProperties created by the first added ResourcePropertiesFactory instance.

Method Detail

getFilenameExtensions

public String[] getFilenameExtensions()

Returns the filename extensions of the ResourcePropertiesFactory in the given order.

Specified by:

getFilenameExtensions in interface org.refcodes.mixin.FilenameExtensionsAccessor

                                       ParseException

Loads the properties from the given file's path. A provided ConfigLocator describes the locations to additional crawl for the desired file. Finally (if nothing else succeeds) the properties are loaded by the provided class's class loader which takes care of loading the properties (in case the file path is a relative path, also the absolute path with a prefixed path delimiter "/" is probed).

Specified by:

toProperties in interface ResourcePropertiesFactory

Parameters:

aResourceClass - The class which's class loader is to take care of loading the properties (from inside a JAR).

aFilePath - The file path of the class's resources from which to load the properties.

aConfigLocator - The ConfigLocator describes the locations to additional crawl for the desired file.

aDelimiters - The path delimiters to be used when parsing the source's properties.

Returns:

The accordingly constructed ResourceProperties.

Throws:

IOException - thrown in case accessing or processing the properties file failed.

ParseException - Signals that an error has been reached unexpectedly while parsing the data to be loaded.

                                       ParseException

Loads or seeks the properties from the given File. A provided ConfigLocator describes the locations to additional crawl for the desired file.

Specified by:
