UnixDomainSocketAddress (Java SE 22 & JDK 22)
Description: declaration: module: java.base, package: java.net, class: UnixDomainSocketAddress
Keywords: java.net.UnixDomainSocketAddress class

Module java.base
Package java.net

# Class UnixDomainSocketAddress

java.lang.Object
java.net.SocketAddress
java.net.UnixDomainSocketAddress

All Implemented Interfaces:
  `Serializable`

public final class UnixDomainSocketAddress extends SocketAddress
A Unix domain socket address. A Unix domain socket address encapsulates a file-system path that Unix domain sockets bind or connect to.

An unnamed `UnixDomainSocketAddress` has an empty path. The local address of a `SocketChannel` to a Unix domain socket that is automatically or implicitly bound will be unnamed.

`Path` objects used to create instances of this class must be obtained from the system-default file system.

- ## Method Details

  - ### of

    public static UnixDomainSocketAddress of(String pathname)
    Creates a UnixDomainSocketAddress from the given path string.
    Parameters:
      `pathname` - The path string, which can be empty
    Returns:
      A UnixDomainSocketAddress
    Throws:
      `InvalidPathException` - If the path cannot be converted to a Path
      `NullPointerException` - if pathname is `null`

  - ### of

    public static UnixDomainSocketAddress of(Path path)
    Creates a UnixDomainSocketAddress for the given path.
    Parameters:
      `path` - The path to the socket, which can be empty
    Returns:
      A UnixDomainSocketAddress
    Throws:
      `IllegalArgumentException` - If the path is not associated with the default file system
      `NullPointerException` - if path is `null`

  - ### getPath

    public Path getPath()
    Returns this address's path.
    Returns:
      this address's path

  - ### hashCode

    public int hashCode()
    Returns the hash code of this `UnixDomainSocketAddress`
    Overrides:
      `hashCode` in class `Object`
    Returns:
      a hash code value for this object
    See Also:
      - `Object.equals(java.lang.Object)`
      - `System.identityHashCode(java.lang.Object)`

  - ### equals

    public boolean equals(Object o)
    Compares this address with another object.
    Overrides:
      `equals` in class `Object`
    Parameters:
      `o` - the reference object with which to compare.
    Returns:
      true if the path fields are equal
    See Also:
      - `Object.hashCode()`
      - `HashMap`

  - ### toString

    public String toString()
    Returns a string representation of this `UnixDomainSocketAddress`.
    Overrides:
      `toString` in class `Object`
    Returns:
      this address's path which may be empty for an unnamed address
