Get() public static method

Gets a UrlLinkFrame object of a specified type from a specified tag, optionally creating and adding one with a specified encoding if none is found.
To create a frame without having to specify the encoding, use Get(Tag,ByteVector,bool).
/// or is /// . /// /// is not exactly four bytes long. ///
public static Get ( Tag tag, ByteVector ident, bool create ) : UrlLinkFrame
tag Tag /// A object to search for the specified /// tag in. ///
ident ByteVector /// A object containing the frame /// identifer to search for. ///
create bool /// A value specifying whether or not to /// create a new frame if an existing frame was not found. ///
return UrlLinkFrame
