Class RefAddr

java.lang.Object
javax.naming.RefAddr
All Implemented Interfaces:
Serializable
Direct Known Subclasses:
BinaryRefAddr, StringRefAddr
public abstract class RefAddr
extends Object
implements Serializable
This class represents the address of a communications end-point. It consists of a type that describes the communication mechanism and an address contents determined by an RefAddr subclass.

For example, an address type could be "BSD Printer Address", which specifies that it is an address to be used with the BSD printing protocol. Its contents could be the machine name identifying the location of the printer server that understands this protocol.

A RefAddr is contained within a Reference.

RefAddr is an abstract class. Concrete implementations of it determine its synchronization properties.

  • Field Details

    • addrType

      protected String addrType
      Contains the type of this address.

  • Constructor Details

    • RefAddr

      protected RefAddr​(String addrType)
      Constructs a new instance of RefAddr using its address type.
      Parameters:
      addrType - A non-null string describing the type of the address.

  • Method Details

    • getType

      public String getType()
      Retrieves the address type of this address.
      Returns:
      The non-null address type of this address.

    • getContent

      public abstract Object getContent()
      Retrieves the contents of this address.
      Returns:
      The possibly null address contents.

    • equals

      public boolean equals​(Object obj)
      Determines whether obj is equal to this RefAddr.

      obj is equal to this RefAddr if all of these conditions are true

      • non-null
      • instance of RefAddr
      • obj has the same address type as this RefAddr (using String.compareTo())
      • both obj and this RefAddr's contents are null or they are equal (using the equals() test).

      Overrides:
      equals in class Object
      Parameters:
      obj - possibly null obj to check.
      Returns:
      true if obj is equal to this refaddr; false otherwise.

      getContent(), getType()

    • hashCode

      public int hashCode()
      Computes the hash code of this address using its address type and contents. The hash code is the sum of the hash code of the address type and the hash code of the address contents.
      Overrides:
      hashCode in class Object
      Returns:
      The hash code of this address as an int.
      See Also:
      Object.hashCode()

    • toString

      public String toString()
      Generates the string representation of this address. The string consists of the address's type and contents with labels. This representation is intended for display only and not to be parsed.
      Overrides:
      toString in class Object
      Returns:
      The non-null string representation of this address.
