Interface ConfigurationPersistenceStrategy2

All Known Subinterfaces:

ConfigurationPersistenceStrategyMultiplexer

public interface ConfigurationPersistenceStrategy2

Defines how configuration data is stored in the configuration resource. This SPI allows application to define their own content structure and node types to be used for configuration data storage.

Resource getCollectionItemResource(Resource resource)

Allows the strategy to transform the given configuration resource according to it's persistent strategies, e.g. fetching the data from a child resource instead of the given resource.

Parameters:

resource - Configuration collection item resource

Returns:

Transformed configuration resource. If null is returned this strategy does not support the given configuration resource.

getResourcePath

java.lang.String getResourcePath(java.lang.String resourcePath)

Allows the strategy to transform the given configuration resource path according to it's persistent strategies, e.g. fetching the data from a child resource instead of the given resource.

Parameters:

resourcePath - Configuration resource path (full path)

Returns:

Transformed configuration resource path. If null is returned this strategy does not support the given configuration resource path.

getCollectionParentResourcePath

java.lang.String getCollectionParentResourcePath(java.lang.String resourcePath)

Allows the strategy to transform the given configuration resource path according to it's persistent strategies, e.g. fetching the data from a child resource instead of the given resource.

Parameters:

resourcePath - Configuration collection parent resource path (full path)

Returns:

Transformed configuration resource path. If null is returned this strategy does not support the given configuration resource path.

getCollectionItemResourcePath

java.lang.String getCollectionItemResourcePath(java.lang.String resourcePath)

Allows the strategy to transform the given configuration resource path according to it's persistent strategies, e.g. fetching the data from a child resource instead of the given resource.

Parameters:

resourcePath - Configuration collection item resource path (full path)

Returns:

Transformed configuration resource path. If null is returned this strategy does not support the given configuration resource path.

getConfigName

java.lang.String getConfigName(java.lang.String configName,
                               java.lang.String relatedConfigPath)

Allows the strategy to transform the given configuration name for nested configurations according to it's persistent strategies, e.g. fetching the data from a child resource instead of the given resource.

Parameters:

configName - Configuration name

relatedConfigPath - Path of a configuration resource that was resolved in context of this configuration name. This can be used to detect if the persistence strategy supports the configuration location. If null it should be assumed that it matches.

Returns:

Transformed configuration name. If null is returned this strategy does not support the given configuration resource path.

getCollectionParentConfigName

java.lang.String getCollectionParentConfigName(java.lang.String configName,
                                               java.lang.String relatedConfigPath)

Parameters:

configName - Configuration name

relatedConfigPath - Path of a configuration resource that was resolved in context of this configuration name. This can be used to detect if the persistence strategy supports the configuration location. If null it should be assumed that it matches.

Returns:

Transformed configuration name. If null is returned this strategy does not support the given configuration resource path.

getCollectionItemConfigName

java.lang.String getCollectionItemConfigName(java.lang.String configName,
                                             java.lang.String relatedConfigPath)

Allows the strategy to transform the given configuration name for nested configurations according to it's persistent strategies, e.g. fetching the data from a child resource instead of the given resource.

Parameters:

configName - Configuration name

relatedConfigPath - Path of a configuration resource that was resolved in context of this configuration name. This can be used to detect if the persistence strategy supports the configuration location. If null it should be assumed that it matches.

Returns:

Transformed configuration name. If null is returned this strategy does not support the given configuration resource path.

persistConfiguration

boolean persistConfiguration(ResourceResolver resourceResolver,
                             java.lang.String configResourcePath,
                             ConfigurationPersistData data)

Stores configuration data for a singleton configuration resource. The changes are written using the given resource resolver. They are not committed, this is left to the caller.

Parameters:

resourceResolver - Resource resolver

configResourcePath - Path to store configuration data to. The resource (and it's parents) may not exist and may have to be created.

data - Configuration data to be stored. All existing properties are erased and replaced with the new ones.

Returns:

true if the data was persisted. false if persisting the data was not accepted by this persistence strategy (in case of error throw an exception).

persistConfigurationCollection

boolean persistConfigurationCollection(ResourceResolver resourceResolver,
                                       java.lang.String configResourceCollectionParentPath,
                                       ConfigurationCollectionPersistData data)

Stores configuration data for a configuration resource collection. The changes are written using the given resource resolver. They are not committed, this is left to the caller.

Parameters:

resourceResolver - Resource resolver

configResourceCollectionParentPath - Parent path to store configuration collection data to. The resource (and it's parents) may not exist and may have to be created.

data - Configuration collection data. All existing collection entries on this context path level are erased and replaced with the new ones.

Returns:

true if the data was persisted. false if persisting the data was not accepted by this persistence strategy (in case of error throw an exception).

deleteConfiguration

boolean deleteConfiguration(ResourceResolver resourceResolver,
                            java.lang.String configResourcePath)

Delete configuration or configuration collection data from repository using the inner-most context path as reference.

Parameters:

resourceResolver - Resource resolver

configResourcePath - Path to store configuration data to. The resource (and it's parents) may not exist and may have to be created.

Returns:

true if the data was delete. false if deleting the data was not accepted by this persistence strategy (in case of error throw an exception).
