public ResolvingLocaleUrlDefinitionDAO(org.apache.tiles.request.ApplicationContext applicationContext)

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.

loadDefinitions

protected Map<String,Definition> loadDefinitions(Locale customizationKey)

Description copied from class: CachingLocaleUrlDefinitionDAO

Tries to load definitions if necessary.

Overrides:

loadDefinitions in class CachingLocaleUrlDefinitionDAO

Parameters:

customizationKey - The locale to use when loading sources.

Returns:

The loaded definitions.

getDefinitionFromResolver

protected Definition getDefinitionFromResolver(String name,
                                   Locale customizationKey)

Returns a definition from the definition resolver.

Overrides:

getDefinitionFromResolver in class CachingLocaleUrlDefinitionDAO

Parameters:

name - The name of the definition.

customizationKey - The customization key to use.

Returns:

The resolved definition.

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
