RefAddr (Java SE 11 & JDK 11 ) (original) (raw)

• java.lang.Object

• • javax.naming.RefAddr

• All Implemented Interfaces:
  [Serializable](../../../java.base/java/io/Serializable.html "interface in java.io")
  Direct Known Subclasses:
  [BinaryRefAddr](BinaryRefAddr.html "class in javax.naming"), [StringRefAddr](StringRefAddr.html "class in javax.naming")

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.
Since:
1.3

• • Field Detail

     * #### addrType  
     protected [String](../../../java.base/java/lang/String.html "class in java.lang") addrType  
     Contains the type of this address.  

  • Constructor Detail

    * #### RefAddr  
    protected RefAddr​([String](../../../java.base/java/lang/String.html "class in java.lang") addrType)  
    Constructs a new instance of RefAddr using its address type.  
    Parameters:  
    `addrType` \- A non-null string describing the type of the address.  

  • Method Detail

    * #### getType  
    public [String](../../../java.base/java/lang/String.html "class in java.lang") getType()  
    Retrieves the address type of this address.  
    Returns:  
    The non-null address type of this address.  
    * #### getContent  
    public abstract [Object](../../../java.base/java/lang/Object.html "class in java.lang") getContent()  
    Retrieves the contents of this address.  
    Returns:  
    The possibly null address contents.  
    * #### equals  
    public boolean equals​([Object](../../../java.base/java/lang/Object.html "class in java.lang") 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](../../../java.base/java/lang/Object.html#equals%28java.lang.Object%29)` in class `[Object](../../../java.base/java/lang/Object.html "class in java.lang")`  
    Parameters:  
    `obj` \- possibly null obj to check.  
    Returns:  
    true if obj is equal to this refaddr; false otherwise.  
    See Also:  
    [getContent()](#getContent%28%29), [getType()](#getType%28%29)  
    * #### 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](../../../java.base/java/lang/Object.html#hashCode%28%29)` in class `[Object](../../../java.base/java/lang/Object.html "class in java.lang")`  
    Returns:  
    The hash code of this address as an int.  
    See Also:  
    [Object.hashCode()](../../../java.base/java/lang/Object.html#hashCode%28%29)  
    * #### toString  
    public [String](../../../java.base/java/lang/String.html "class in java.lang") 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](../../../java.base/java/lang/Object.html#toString%28%29)` in class `[Object](../../../java.base/java/lang/Object.html "class in java.lang")`  
    Returns:  
    The non-null string representation of this address.
