    Writes the structure and/or resource record(s) of an existing file.
    Common usages of this method are saving the resource information after creating, importing or restoring complete files where all file header attributes are changed. Both the structure and resource records get written. Thus, using this method affects all siblings of a resource! Use I_CmsVfsDriver.writeResourceState(CmsDbContext, CmsProject, CmsResource, int, boolean) instead if you just want to update the file state, e.g. of a single sibling.
    The file state is set to "changed", unless the current state is "new" or "deleted". The "changed" argument allows to choose whether the structure or resource state, or none of them, is set to "changed".
    The rating of the file state values is as follows:
    unchanged < changed < new < deleted
    Second, the "state" of the resource is the structure state, if the structure state has a higher file state value than the resource state. Otherwise the file state is the resource state.

    Writes file state in either the structure or resource record, or both of them.
    This method allows to change the resource state to any state by setting the desired state value in the specified CmsResource instance.
    This method is frequently used while resources are published to set the file state back to "unchanged".
    Only file state attributes. get updated here. Use I_CmsVfsDriver.writeResource(CmsDbContext, CmsUUID, CmsResource, int) instead to write the complete file header.
