Detailed Description

A handle is like a pointer: refers to an underlying implementation object.

Copying the handle does not copy the object.

Handles can be null, like a 0 pointer. Use isValid(), isNull() or the conversion to bool to test for a null handle.

QPID_CLIENT_INLINE_EXTERN bool qpid::client::Handle::isValid ( ) const [inline]
Returns:
true if handle is valid, i.e. not null.
