Method Detail

getDefinitionsFactory

public DefinitionsFactory getDefinitionsFactory(String key)

Returns a definition factory given its key.

Parameters:

key - The key of the needed definitions factory.

Returns:

the definitions factory used by this container. If the key is not valid, the default factory will be returned.

getProperDefinitionsFactory

public DefinitionsFactory getProperDefinitionsFactory(String key)

Returns the proper definition factory for the given key, i.e. if the key is not present, null will be returned.

Parameters:

key - The key of the needed definitions factory.

Returns:

the definitions factory used by this container. If the key is not valid, null will be returned.

setDefinitionsFactory

@Deprecated
public void setDefinitionsFactory(String key,
                                             DefinitionsFactory definitionsFactory,
                                             Map<String,String> initParameters)

Deprecated. Use setDefinitionsFactory(String, DefinitionsFactory).

Set the definitions factory. This method first ensures that the container has not yet been initialized.

Parameters:

key - The key under which the definitions factory is catalogued.

definitionsFactory - the definitions factory for this instance.

initParameters - The init parameters to configure the definitions factory.

setDefinitionsFactory

public void setDefinitionsFactory(String key,
                                  DefinitionsFactory definitionsFactory)

Set the definitions factory. This method first ensures that the container has not yet been initialized.

Parameters:

key - The key under which the definitions factory is catalogued.

definitionsFactory - the definitions factory for this instance.

Since:

2.1.0

setKeyExtractor

public void setKeyExtractor(KeyedDefinitionsFactoryTilesContainer.KeyExtractor keyExtractor)

Sets the key extractor to use.

Parameters:

keyExtractor - The key extractor.

getDefinition

protected Definition getDefinition(String definitionName,
                                   TilesRequestContext request)

Returns a definition specifying its name.

Overrides:

getDefinition in class BasicTilesContainer

Parameters:

definitionName - The name of the definition to find.

request - The request context.

Returns:

The definition, if found.

getDefinitionsFactoryKey

protected String getDefinitionsFactoryKey(TilesRequestContext request)

Returns the definitions factory key.

Parameters:

request - The request object.

Returns:

The needed factory key.
