public class ResolvingLocaleUrlDefinitionDAO
extends CachingLocaleUrlDefinitionDAO

A definitions DAO (loading URLs and using Locale as a customization key) that caches definitions that have been loaded and resolves inheritances.

It can check if the URLs change, but by default this feature is turned off.

Since:

2.1.0

ResolvingLocaleUrlDefinitionDAO

public ResolvingLocaleUrlDefinitionDAO()

Method Detail

loadParentDefinitions

protected Map<String,Definition> loadParentDefinitions(Locale parentLocale)

Loads parent definitions, i.e. definitions mapped to a parent locale.

Overrides:

loadParentDefinitions in class CachingLocaleUrlDefinitionDAO

Parameters:

parentLocale - The locale to use when loading URLs.

Returns:

The loaded parent definitions.

postDefinitionLoadOperations

protected void postDefinitionLoadOperations(Map<String,Definition> localeDefsMap,
                                            Locale customizationKey)

Operations to be done after definitions are loaded.

Overrides:

postDefinitionLoadOperations in class CachingLocaleUrlDefinitionDAO

Parameters:

localeDefsMap - The loaded definitions.

customizationKey - The locale to use when loading URLs.

resolveInheritances

protected void resolveInheritances(Map<String,Definition> map,
                                   Locale locale)

Resolve locale-specific extended instances.

Parameters:

map - The definition map containing the definitions to resolve.

locale - The locale to use.

Throws:

NoSuchDefinitionException - If a parent definition is not found.

Since:

2.1.0

resolveInheritance

protected void resolveInheritance(Definition definition,
                                  Map<String,Definition> definitions,
                                  Locale locale,
                                  Set<String> alreadyResolvedDefinitions)

Resolve locale-specific inheritance. First, resolve parent's inheritance, then set template to the parent's template. Also copy attributes setted in parent, and not set in child If instance doesn't extend anything, do nothing.

Parameters:

definition - The definition to resolve

definitions - The definitions to take when obtaining a parent definition.

locale - The locale to use.

alreadyResolvedDefinitions - The set of the definitions that have been already resolved.

Throws:

NoSuchDefinitionException - If an inheritance can not be solved.

Since:

2.1.0

copyDefinitionMap

protected Map<String,Definition> copyDefinitionMap(Map<String,Definition> localeDefsMap)

Copies the definition map to be passed to a higher level of customization key.

Overrides:

copyDefinitionMap in class CachingLocaleUrlDefinitionDAO

Parameters:

localeDefsMap - The map of definition to be copied.

Returns:

The copy of the definition map. This particular implementation deep-copies the localeDefsMap into a LinkedHashMap.

Since:

2.1.4
