getItem

public String getItem(@Context
                      javax.servlet.http.HttpServletRequest request,
                      String rawRepositoryName,
                      String rawWorkspaceName,
                      String path,
                      int depth)
               throws org.codehaus.jettison.json.JSONException,
                      org.jboss.resteasy.spi.UnauthorizedException,
                      javax.jcr.RepositoryException

Handles GET requests for an item in a workspace.

Parameters:

request - the servlet request; may not be null or unauthenticated

rawRepositoryName - the URL-encoded repository name

rawWorkspaceName - the URL-encoded workspace name

path - the path to the item

depth - the depth of the node graph that should be returned if path refers to a node. @{code 0} means return the requested node only. A negative value indicates that the full subgraph under the node should be returned. This parameter defaults to 0 and is ignored if path refers to a property.

Returns:

the JSON-encoded version of the item (and, if the item is a node, its subgraph, depending on the value of depth)

Throws:

org.jboss.resteasy.spi.NotFoundException - if the named repository does not exists, the named workspace does not exist, or the user does not have access to the named workspace

org.codehaus.jettison.json.JSONException - if there is an error encoding the node

org.jboss.resteasy.spi.UnauthorizedException - if the given login information is invalid

javax.jcr.RepositoryException - if any other error occurs

postItem

public javax.ws.rs.core.Response postItem(@Context
                                          javax.servlet.http.HttpServletRequest request,
                                          String rawRepositoryName,

                                          javax.jcr.RepositoryException,
                                          org.codehaus.jettison.json.JSONException

Adds the content of the request as a node (or subtree of nodes) at the location specified by path.

The primary type and mixin type(s) may optionally be specified through the jcr:primaryType and jcr:mixinTypes properties.

Parameters:

request - the servlet request; may not be null or unauthenticated

rawRepositoryName - the URL-encoded repository name

rawWorkspaceName - the URL-encoded workspace name

path - the path to the item

requestContent - the JSON-encoded representation of the node or nodes to be added

Returns:

the JSON-encoded representation of the node or nodes that were added. This will differ from requestContent in that auto-created and protected properties (e.g., jcr:uuid) will be populated.

Throws:

org.jboss.resteasy.spi.NotFoundException - if the parent of the item to be added does not exist

org.jboss.resteasy.spi.UnauthorizedException - if the user does not have the access required to create the node at this path

org.codehaus.jettison.json.JSONException - if there is an error encoding the node

javax.jcr.RepositoryException - if any other error occurs

deleteItem

public void deleteItem(@Context
                       javax.servlet.http.HttpServletRequest request,
                       String rawRepositoryName,
                       String rawWorkspaceName,
                       String path)
                throws org.jboss.resteasy.spi.NotFoundException,

Deletes the item at path.

Parameters:

request - the servlet request; may not be null or unauthenticated

rawRepositoryName - the URL-encoded repository name

rawWorkspaceName - the URL-encoded workspace name

path - the path to the item

Throws:

org.jboss.resteasy.spi.NotFoundException - if no item exists at path

org.jboss.resteasy.spi.UnauthorizedException - if the user does not have the access required to delete the item at this path

javax.jcr.RepositoryException - if any other error occurs

putItem

public String putItem(@Context
                      javax.servlet.http.HttpServletRequest request,
                      String rawRepositoryName,
                      String rawWorkspaceName,
                      String path,
                      String requestContent)
               throws org.jboss.resteasy.spi.UnauthorizedException,
                      org.codehaus.jettison.json.JSONException,
                      javax.jcr.RepositoryException

Updates the properties at the path.

If path points to a property, this method expects the request content to be either a JSON array or a JSON string. The array or string will become the values or value of the property. If path points to a node, this method expects the request content to be a JSON object. The keys of the objects correspond to property names that will be set and the values for the keys correspond to the values that will be set on the properties.

Parameters:

request - the servlet request; may not be null or unauthenticated

rawRepositoryName - the URL-encoded repository name

rawWorkspaceName - the URL-encoded workspace name

path - the path to the item

requestContent - the JSON-encoded representation of the values and, possibly, properties to be set

Returns:

the JSON-encoded representation of the node on which the property or properties were set.

Throws:

org.jboss.resteasy.spi.NotFoundException - if the parent of the item to be added does not exist

org.jboss.resteasy.spi.UnauthorizedException - if the user does not have the access required to create the node at this path

org.codehaus.jettison.json.JSONException - if there is an error encoding the node

javax.jcr.RepositoryException - if any other error occurs
