The TIBCO Messaging Appliance P-7500 system supports the use of subjects for both publishing and subscribing.Subject strings are NULL-terminated UTF-8 strings where the string of characters is composed of one or more levels (also called elements), separated by a “.” delimiter, in the format “a.b.c”.The maximum total character length of subjects (including dot separators) is 196 characters. The maximum element length is 127 characters.All characters except the NULL character are valid within a subject string, although ’_’, ‘*’, and ‘>’ have special semantics to the P-7500 system. Refer to Table 5. Characters in subject strings are case sensitive.
Character Name It is illegal for applications to send to subjects with underscore as the first character of the first element, except _INBOX and _LOCAL.It is legal to use underscore elsewhere in subject names. It is illegal to incorporate the dot character into an element by using an escape sequence. Wildcard element: Matches one or more trailing elements.
