Field Detail

Original Enumeration

Creates AbstractNamingEnumeration object.

Closes enumeration. The method does nothing.

Specified by:

close in interface javax.naming.NamingEnumeration

Determines whether there are any more elements in the enumeration. This method allows naming exceptions encountered while determining whether there are more elements to be caught and handled by the application.

Specified by:

hasMore in interface javax.naming.NamingEnumeration

Returns:

true If there is more in the enumeration; false otherwise.

Throws:

javax.naming.NamingException - If a naming exception is encountered while attempting to determine whether there is another element in the enumeration. See NamingException and its subclasses for the possible naming exceptions.

Tests if this enumeration contains more elements.

Specified by:

hasMoreElements in interface java.util.Enumeration

Returns:

true if and only if this enumeration object contains at least one more element to provide; false otherwise.

Retrieves the next element in the enumeration. This method allows naming exceptions encountered while retrieving the next element to be caught and handled by the application.

Note that next() can also throw the runtime exception NoSuchElementException to indicate that the caller is attempting to enumerate beyond the end of the enumeration. This is different from a NamingException, which indicates that there was a problem in obtaining the next element, for example, due to a referral or server unavailability, etc.

Specified by:

next in interface javax.naming.NamingEnumeration

Returns:

The possibly null element in the enumeration. null is only valid for enumerations that can return null.

Throws:

javax.naming.NamingException - If a naming exception is encountered while attempting to retrieve the next element. See NamingException and its subclasses for the possible naming exceptions.

java.util.NoSuchElementException - If attempting to get the next element when none is available.

Returns the next element of this enumeration if this enumeration object has at least one more element to provide.

Specified by:

nextElement in interface java.util.Enumeration

Returns:

The next element of this enumeration.

Throws:

java.util.NoSuchElementException - If no more elements exist.
