从接口复制的说明: I_CmsResourceWrapper

Copies a resource.

First should be a check if the source and/or the destination are handled by this resource wrapper.

It is possible that the path in the source or in the destination are virtual paths and so has to be translated into valid paths existing in the VFS to copy the resource.

参数:

cms - the initialized CmsObject

source - the name of the resource to copy

siblingMode - indicates how to handle siblings during copy

返回:

true if the copy action was handled by this resource wrapper otherwise false

抛出:

CmsException - if something goes wrong

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