Field Detail

m_exportpointLookupMap

protected java.util.Map<java.lang.String,java.lang.String> m_exportpointLookupMap

Constructor Detail

CmsExportPointDriver

public CmsExportPointDriver(java.util.Set<CmsExportPoint> exportpoints)

Constructor for a CmsExportPointDriver.

Parameters:

exportpoints - the list of export points

CmsExportPointDriver

protected CmsExportPointDriver()

Empty default constructor, necessary for subclasses which may need to do initialization differently.

Method Detail

createFolder

public void createFolder(java.lang.String resourceName,
                         java.lang.String exportpoint)

If required, creates the folder with the given root path in the real file system.

Specified by:

createFolder in interface I_CmsExportPointDriver

Parameters:

resourceName - the root path of the folder to create

exportpoint - the export point to create the folder in

deleteResource

public void deleteResource(java.lang.String resourceName,
                           java.lang.String exportpoint)

Deletes a file or a folder in the real file sytem.

If the given resource name points to a folder, then this folder is only deleted if it is empty. This is required since the same export point RFS target folder may be used by multiple export points. For example, this is usually the case with the /WEB-INF/classes/ and /WEB-INF/lib/ folders which are export point for multiple modules. If all resources in the RFS target folder where deleted, uninstalling one module would delete the export classes and lib resources of all other modules.

Specified by:

deleteResource in interface I_CmsExportPointDriver

Parameters:

resourceName - the root path of the resource to be deleted

exportpoint - the name of the export point

getExportPoint

public java.lang.String getExportPoint(java.lang.String rootPath)

Returns the export point path for the given resource root path, or null if the resource is not contained in any export point.

Specified by:

getExportPoint in interface I_CmsExportPointDriver

Parameters:

rootPath - the root path of a resource in the OpenCms VFS

Returns:

the export point path for the given resource, or null if the resource is not contained in any export point

getExportPointPaths

public java.util.Set<java.lang.String> getExportPointPaths()

Returns the set of all VFS paths that are exported as an export point.

Specified by:

getExportPointPaths in interface I_CmsExportPointDriver

Returns:

the set of all VFS paths that are exported as an export point

writeFile

public void writeFile(java.lang.String resourceName,
                      java.lang.String exportpoint,
                      byte[] content)

Writes the file with the given root path to the real file system.

If required, missing parent folders in the real file system are automatically created.

Specified by:

writeFile in interface I_CmsExportPointDriver

Parameters:

resourceName - the root path of the file to write

exportpoint - the export point to write file to

content - the contents of the file to write

getExportPointFile

protected java.io.File getExportPointFile(java.lang.String rootPath,
                                          java.lang.String exportpoint)

Returns the File for the given export point resource.

Parameters:

rootPath - name of a file in the VFS

exportpoint - the name of the export point

Returns:

the File for the given export point resource

writeResource

protected void writeResource(java.io.File file,
                             byte[] content)

Writes file data to the RFS.

Parameters:

file - the RFS file location

content - the file content

writeResource

protected void writeResource(java.lang.String resourceName,
                             java.lang.String exportpoint,
                             byte[] content)

Writes (if required creates) a resource with the given name to the real file system.

Parameters:

resourceName - the root path of the resource to write

exportpoint - the name of the export point

content - the contents of the file to write
