Class javax.naming.Binding
java.lang.Object
|
+----javax.naming.NameClassPair

+----javax.naming.Binding
- public class Binding
- extends NameClassPair
This class represents a name-to-object binding found in a context.
A context consists of name-to-object bindings.
The Binding class represents such a binding. It consists
of a name and an object. The Context.listBindings()
method returns an enumeration of Binding.
Use subclassing for naming systems that generate contents of
a binding dynamically.
A Binding instance is not synchronized against concurrent access by multiple
threads. Threads that need to access a Binding concurrently should
synchronize amongst themselves and provide the necessary locking.
The serialized form of a Binding object consists of the same
fields as the serialized form of its NameClassPair superclass, followed
by the serialized representation of the bound object.
-
Binding(String, Object)
- Constructs an instance of a Binding given its name and object.
-
Binding(String, Object, boolean)
- Constructs an instance of a Binding given its name, object, and whether
the name is relative.
-
Binding(String, String, Object)
- Constructs an instance of a Binding given its name, class name, and object.
-
Binding(String, String, Object, boolean)
- Constructs an instance of a Binding given its
name, class name, object, and whether the name is relative.
-
getClassName()
- Retrieves the class name of the object bound to the name of this binding.
-
getObject()
- Retrieves the object bound to the name of this binding.
-
setObject(Object)
- Sets the object associated with this binding.
-
toString()
- Generates the string representation of this binding.
Binding
public Binding(String name,
Object obj)
- Constructs an instance of a Binding given its name and object.
getClassName() will return
the class name of obj (or null if obj is null)
unless the class name has been explicitly set using setClassName()
- Parameters:
- name - The non-null name of the object. It is relative
to the target context (which is
named by the first parameter of the
listBindings()
method)
- obj - The possibly null object bound to name.
- See Also:
- setClassName
Binding
public Binding(String name,
Object obj,
boolean isRelative)
- Constructs an instance of a Binding given its name, object, and whether
the name is relative.
getClassName() will return the class name of obj
(or null if obj is null) unless the class name has been
explicitly set using setClassName()
- Parameters:
- name - The non-null string name of the object.
- obj - The possibly null object bound to name.
- isRelative - true if
name
is a name relative
to the target context (which is named by
the first parameter of the listBindings()
method);
false if name
is a URL string.
- See Also:
- isRelative, setRelative, setClassName
Binding
public Binding(String name,
String className,
Object obj)
- Constructs an instance of a Binding given its name, class name, and object.
- Parameters:
- name - The non-null atomic name of the object. It is relative
to the target context (which is
named by the first parameter of the
listBindings()
method)
- className - The possibly null class name of the object
bound to name. If null, the class name of obj is
returned by getClassName(). If obj is also
null, getClassName() will return null.
- obj - The possibly null object bound to name.
- See Also:
- setClassName
Binding
public Binding(String name,
String className,
Object obj,
boolean isRelative)
- Constructs an instance of a Binding given its
name, class name, object, and whether the name is relative.
- Parameters:
- name - The non-null string name of the object.
- className - The possibly null class name of the object
bound to name. If null, the class name of obj is
returned by getClassName(). If obj is also
null, getClassName() will return null.
- obj - The possibly null object bound to name.
- isRelative - true if
name
is an atomic name relative
to the target context (which is named by
the first parameter of the listBindings()
method);
false if name
is a URL string.
- See Also:
- isRelative, setRelative, setClassName
getClassName
public String getClassName()
- Retrieves the class name of the object bound to the name of this binding.
If the class name has been set explicitly, return it.
Otherwise, if this binding contains a non-null object,
that object's class name is used. Otherwise, null is returned.
- Returns:
- A possibly null string containing class name of object bound.
- Overrides:
- getClassName in class NameClassPair
getObject
public Object getObject()
- Retrieves the object bound to the name of this binding.
- Returns:
- The object bound; null if this binding does not contain an object.
setObject
public void setObject(Object obj)
- Sets the object associated with this binding.
- Parameters:
- obj - The possibly null object to use.
toString
public String toString()
- Generates the string representation of this binding.
The string representation consists of the string representation
of the name/class pair and the string representation of
this binding's object, separated by ':'.
The contents of this string is useful
for debugging and is not meant to be interpreted programmatically.
- Returns:
- The non-null string representation of this binding.
- Overrides:
- toString in class NameClassPair
