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).

                            @NotNull 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).
