Hi Chris,
possible wording for your last paragraph:
To retrieve a string representation of the hostname, or in the
absence of a hostname, the string form of the address, use {@link
#getHostString()}, rather than parsing the toString string representation.
or
It is advised to use {@link#getHostString()} to obtain a hostname string, or
in the absence of a hostname, a string form of the address. Do not rely on
parsing the toString() return value to obtain a hostname string.
regards
Mark

Subject: 8241995: Clarify InetSocketAddress::toString specification
As noted in a recent thread [1], the wording of InetSocketAddress::toString
could be improved a little, to avoid any potential confusion about how
and when "<unresolved>" is displayed. It was also suggested that a link
to getHostString could be added.
Below is an initial suggestion. It does not change the spec, just adds
some examples and guidance. I'm relatively happy with the examples, but
less so with the final advise paragraph. Suggestions welcome.
- /**
- * Constructs a string representation of this InetSocketAddress.
- * This String is constructed by calling toString() on the InetAddress
- * and concatenating the port number (with a colon). If the address
- * is an IPv6 address, the IPv6 literal is enclosed in square brackets.
- * If the address is {@linkplain #isUnresolved() unresolved},
- * {@code <unresolved>} is displayed in place of the address literal.
- *
- * @return a string representation of this object.
- */
- public String toString() { ... }
