Description copied from interface: IRestClient

Publishes, or uploads, a local file to the workspace at the specified path. This method does not utilize any versioning, and is equivalent to calling "publish(workspace,path,file,false) ".

Specified by:

publish in interface IRestClient

Parameters:

workspace - the workspace where the resource will be published (never null)

path - the unencoded path to the folder where the file will be published (never null)

file - the resource being published (never null)

Returns:

a status of the publishing operation outcome (never null)

fileExists

public boolean fileExists(File file,
                          Workspace workspace,
                          String path)
                   throws Exception

Description copied from interface: IRestClient

Checks if the given file exists or not on the server, by issuing a GET request.

Specified by:

fileExists in interface IRestClient

Parameters:

file - the file whose existence is checked, (never null)

workspace - the workspace where the file is/could be located (never null)

path - the path in the ModeShape workspace to the parent of the file (never null)

Returns:

true if the file exists on the server, or false otherwise.

publish

public Status publish(Workspace workspace,
                      String path,
                      File file,
                      boolean useVersioning)

Description copied from interface: IRestClient

Publishes, or uploads, a local file to the workspace at the specified path. This method allows the client to specify whether the uploaded file should be versioned. If so, this method will add the "mix:versionable" mixin to the "nt:file" node, and subsequent attempts to re-publish will result in new versions in the version history of the file. If no versioning is to be done, then no version history is maintained for the file, and subsequent attemps to re-publish will simply overwrite any existing content.

Specified by:

publish in interface IRestClient

Parameters:

workspace - the workspace where the resource will be published (never null)

path - the unencoded path to the folder where the file will be published (never null)

file - the resource being published (never null)

useVersioning - true if the uploaded file should be versioned, or false if no JCR versioning be used

Returns:

a status of the publishing operation outcome (never null)

                        String path,
                        File file)

Description copied from interface: IRestClient

Unpublishes, or deletes, the resource at the specified path in the workspace. If a file being unpublished is not found in the workspace an info status is returned.

Specified by:

unpublish in interface IRestClient

Parameters:

workspace - the workspace where the resource will be unpublished (never null)
