JRE 8 rt.jar - javax.* Package Source Code

JRE 8 rt.jar is the JAR file for JRE 8 RT (Runtime) libraries. JRE (Java Runtime) 8 is the runtime environment included in JDK 8. JRE 8 rt.jar libraries are divided into 6 packages:

com.* - Internal Oracle and Sun Microsystems libraries
java.* - Standard Java API libraries.
javax.* - Extended Java API libraries.
jdk.* -  JDK supporting libraries.
org.* - Third party libraries.
sun.* - Old libraries developed by Sun Microsystems.

/**
  * This interface is for enumerating lists returned by
  * methods in the javax.naming and javax.naming.directory packages.
  * It extends Enumeration to allow as exceptions to be thrown during
  * the enumeration.
  *<p>
  * When a method such as list(), listBindings(), or search() returns
  * a NamingEnumeration, any exceptions encountered are reserved until
  * all results have been returned. At the end of the enumeration, the
  * exception is thrown (by hasMore());
  * <p>
  * For example, if the list() is
  * returning only a partial answer, the corresponding exception would
  * be PartialResultException. list() would first return a NamingEnumeration.
  * When the last of the results has been returned by the NamingEnumeration's
  * next(), invoking hasMore() would result in PartialResultException being thrown.
  *<p>
  * In another example, if a search() method was invoked with a specified
  * size limit of 'n'. If the answer consists of more than 'n' results,
  * search() would first return a NamingEnumeration.
  * When the n'th result has been returned by invoking next() on the
  * NamingEnumeration, a SizeLimitExceedException would then thrown when
  * hasMore() is invoked.
  *<p>
  * Note that if the program uses hasMoreElements() and nextElement() instead
  * to iterate through the NamingEnumeration, because these methods
  * cannot throw exceptions, no exception will be thrown. Instead,
  * in the previous example, after the n'th result has been returned by
  * nextElement(), invoking hasMoreElements() would return false.
  *<p>
  * Note also that NoSuchElementException is thrown if the program invokes
  * next() or nextElement() when there are no elements left in the enumeration.
  * The program can always avoid this exception by using hasMore() and
  * hasMoreElements() to check whether the end of the enumeration has been reached.
  *<p>
  * If an exception is thrown during an enumeration,
  * the enumeration becomes invalid.
  * Subsequent invocation of any method on that enumeration
  * will yield undefined results.
