  The identifiers of the WorkSpaces. You cannot combine this parameter with any other filter.

  Because the <a>CreateWorkspaces</a> operation is asynchronous, the identifier it returns is not immediately
  available. If you immediately call <a>DescribeWorkspaces</a> with this identifier, no information is returned.

  <b>NOTE:</b> This method appends the values to the existing list (if any). Use
  {@link #setWorkspaceIds(java.util.Collection)} or {@link #withWorkspaceIds(java.util.Collection)} if you want to
  override the existing values.
