Class CmsResourceWrapperReplaceDeleted

java.lang.Object

org.opencms.file.wrapper.A_CmsResourceWrapper

org.opencms.file.wrapper.CmsResourceWrapperReplaceDeleted

All Implemented Interfaces:

I_CmsResourceWrapper

public class CmsResourceWrapperReplaceDeleted
extends A_CmsResourceWrapper

Resource wrapper which intercepts createResource calls and substitutes them with replaceResource if there is already a deleted file at the same path.

This is useful because when accessing a repository, users can neither see nor publish deleted files, and thus can not re-create a file of state "deleted".

Description copied from interface: I_CmsResourceWrapper

Creates a new resource of the given resource type with the provided content and properties.

First should be a check if the resourcename is handled by this resource wrapper.

It is possible that the path in the resourcename is a virtual path and so has to be translated into a valid path existing in the VFS to create the resource.

Specified by:

createResource in interface I_CmsResourceWrapper

Overrides:

createResource in class A_CmsResourceWrapper

Parameters:

cms - the initialized CmsObject

resourcename - the name of the resource to create (full path)

type - the type of the resource to create

content - the content for the new resource

properties - the properties for the new resource

Returns:

the created resource or null if not handled by this resource wrapper

Throws:

CmsException - if something goes wrong

CmsIllegalArgumentException - if the source argument is null or of length 0

Description copied from interface: I_CmsResourceWrapper
