Class HostAndPort

java.lang.Object
com.google.common.net.HostAndPort
All Implemented Interfaces:
Serializable
@Beta @Immutable @GwtCompatible @Deprecated(since="2022-12-01") public final class HostAndPort extends Object implements Serializable
Deprecated.
The Google Guava Core Libraries are deprecated and will not be part of the AEM SDK after April 2023
An immutable representation of a host and port.

Example usage: 

  HostAndPort hp = HostAndPort.fromString("[2001:db8::1]")
      .withDefaultPort(80)
      .requireBracketsForIPv6();
  hp.getHostText();  // returns "2001:db8::1"
  hp.getPort();      // returns 80
  hp.toString();     // returns "[2001:db8::1]:80"

Here are some examples of recognized formats:

Note that this is not an exhaustive list, because these methods are only concerned with brackets, colons, and port numbers. Full validation of the host field (if desired) is the caller's responsibility.

    • getHostText

      public String getHostText()
      Deprecated.
      Returns the portion of this HostAndPort instance that should represent the hostname or IPv4/IPv6 literal.

      A successful parse does not imply any degree of sanity in this field. For additional validation, see the HostSpecifier class.

    • hasPort

      public boolean hasPort()
      Deprecated.
      Return true if this instance has a defined port.

    • getPort

      public int getPort()
      Deprecated.
      Get the current port number, failing if no port is defined.
      Returns:
      a validated port number, in the range [0..65535]
      Throws:
      IllegalStateException - if no port is defined. You can use withDefaultPort(int) to prevent this from occurring.

    • getPortOrDefault

      public int getPortOrDefault(int defaultPort)
      Deprecated.
      Returns the current port number, with a default if no port is defined.

    • fromParts

      public static HostAndPort fromParts(String host, int port)
      Deprecated.
      Build a HostAndPort instance from separate host and port values.

      Note: Non-bracketed IPv6 literals are allowed. Use requireBracketsForIPv6() to prohibit these.

      Parameters:
      host - the host string to parse. Must not contain a port number.
      port - a port number from [0..65535]
      Returns:
      if parsing was successful, a populated HostAndPort object.
      Throws:
      IllegalArgumentException - if host contains a port number, or port is out of range.

    • fromString

      public static HostAndPort fromString(String hostPortString)
      Deprecated.
      Split a freeform string into a host and port, without strict validation. Note that the host-only formats will leave the port field undefined. You can use withDefaultPort(int) to patch in a default value.
      Parameters:
      hostPortString - the input string to parse.
      Returns:
      if parsing was successful, a populated HostAndPort object.
      Throws:
      IllegalArgumentException - if nothing meaningful could be parsed.

    • withDefaultPort

      public HostAndPort withDefaultPort(int defaultPort)
      Deprecated.
      Provide a default port if the parsed string contained only a host. You can chain this after fromString(String) to include a port in case the port was omitted from the input string. If a port was already provided, then this method is a no-op.
      Parameters:
      defaultPort - a port number, from [0..65535]
      Returns:
      a HostAndPort instance, guaranteed to have a defined port.

    • requireBracketsForIPv6

      public HostAndPort requireBracketsForIPv6()
      Deprecated.
      Generate an error if the host might be a non-bracketed IPv6 literal.

      URI formatting requires that IPv6 literals be surrounded by brackets, like "[2001:db8::1]". Chain this call after fromString(String) to increase the strictness of the parser, and disallow IPv6 literals that don't contain these brackets.

      Note that this parser identifies IPv6 literals solely based on the presence of a colon. To perform actual validation of IP addresses, see the InetAddresses.forString(String) method.

      Returns:
      this, to enable chaining of calls.
      Throws:
      IllegalArgumentException - if bracketless IPv6 is detected.

    • equals

      public boolean equals(@Nullable Object other)
      Deprecated.
      Overrides:
      equals in class Object

    • hashCode

      public int hashCode()
      Deprecated.
      Overrides:
      hashCode in class Object

    • toString

      public String toString()
      Deprecated.
      Rebuild the host:port string, including brackets if necessary.
      Overrides:
      toString in class Object
