Interface ResourceManager

@ConsumerType
public interface ResourceManager

The ResourceManager defines the API which might be asked to find, copy, move and delete specific resources.

Implementors should ensure that a ResourceManager can be retrieved adapting a SlingHttpServletRequest by implementing an AdapterFactory.

Method Summary

Modifier and Type	Method	Description
boolean	copy(Resource resource, java.lang.String destUri, int depth)	Copies all properties and resources of the implementor to the destUri.
java.util.List<Resource>	find(Resource resource, java.lang.String query)	Returns the query result from the provided query statement as a List.
boolean	move(Resource resource, java.lang.String destUri)	Moves all properties and resources of the implementor to the destUri.

Method Detail

copy

boolean copy(Resource resource,
             java.lang.String destUri,
             int depth)
      throws java.lang.UnsupportedOperationException,
             RequestException,
             RestException

Copies all properties and resources of the implementor to the destUri. The method expects the destUri to be a non-remote URI, absolute, normalized and within the same name space as the resource.

The method should throw a RequestException with a HTTP status 403 if the destination is not part of the resources ResourceProvider name space. If the parent resource of the destination does not exist the method should throw a RequestException with the HTTP status code 412. In case an error occurs while copying one of the resources child elements a RequestException with HTTP status code 207 pointing to the failing resource should be thrown.

Parameters:

resource - Resource to copy

destUri - Destination URI to copy resource to

depth - Depth value indicating the depth of the copy. A value of -1 is equal to infinite, a value of 0 indicates that only the resource itself and its properties should be copied but no children.

Returns:

true if destination has been created, false if it has been overwritten.

Throws:

java.lang.UnsupportedOperationException - If the operation is not supported for the resource

RequestException - if a precondition for the operation is not met

RestException - if an error occurs during the operation

move

boolean move(Resource resource,
             java.lang.String destUri)
      throws java.lang.UnsupportedOperationException,
             RequestException,
             RestException

Moves all properties and resources of the implementor to the destUri. The method expects the destUri to be a non-remote URI, absolute, normalized and within the same name space as the resource. The method should throw a RequestException with a HTTP status 403 if the destination is not part of the resources ResourceProvider name space. If the parent resource of the destination does not exist the method should throw a RequestException with the HTTP status code 412. In case an error occurs while copying one of the resources child elements a RequestException with HTTP status code 207 pointing to the failing resource should be thrown.

Parameters:

resource - Resource to move

destUri - Destination URI to move resource to

Returns:

true if destination has been created, false if it has been overwritten.

Throws:

java.lang.UnsupportedOperationException - If the operation is not supported for the resource

RequestException - if a precondition for the operation is not met

RestException - if an error occurs during the operation

find

java.util.List<Resource> find(Resource resource,
                              java.lang.String query)
                       throws java.lang.UnsupportedOperationException,
                              RequestException,
                              RestException

Returns the query result from the provided query statement as a List.

Parameters:

query - Query statement

Returns:

A List of resources found matching the query

Throws:

java.lang.UnsupportedOperationException - If the operation is not supported for the resource

RequestException - if a precondition for the operation is not met

RestException - if an error occurs during the search
