Called by Lightstreamer Kernel through the Remote Server to ask for the allowance of a publishing Mode for an Item. A publishing Mode can or cannot be allowed depending on the User. In this default implementation, the Metadata Adapter poses no restriction. As a consequence, conflicting Modes may be both allowed for the same Item, so the Clients should ensure that the same Item cannot be requested in two conflicting Modes.

public: bool IsModeAllowed(string user, string item, Mode mode);

public virtual bool IsModeAllowed(string user, string item, Mode mode);

Public virtual Function IsModeAllowed(user As string, item As string, mode As Mode) As bool
