A concrete implementation of the EnumIterator interface. It is a very simple implementation that can enumerate over in-memory data passed either as an array of objects or a list (java.util.List). The enumeration contents can be of javax.xml.soap.SOAPElement type, simple types such as java.lang.Integer, etc. or Axis generated Java beans. The SimpleEnumIterator can only be used with transient type of enumerations.
The Globus-provided indexed file enum iterator
A memory efficient implementation that can enumerate over data stored in an indexed file created by IndexedObjectFileWriter. The indexed file format is optimized for retrieving objects in a sequential and random manner. The IndexedObjectFileEnumIterator uses the IndexedObjectFileReader to read the indexed file and quickly locate and retrieve the next set of objects of the enumeration. The IndexedObjectFileEnumIterator can be used with transient and persistent types of enumerations.
A simple iterator which persists objects to disk
This iterator makes no attempt to respect any values of IterationConstraints except for maxElements.
A relatively complete implementation of the EnumIterator spec
This iterator uses threads to respect maxTime constraints, as well as respecting maxCharacters. Elements overflowing either of these constraints, however, are lost, and waits for threads are not optimized.
The default and most complete implementation of the EnumIterator spec
This iterator uses the Java 5 java.util.concurrent package to fully support the WS-Enumeration specification for an EnumIterator implementation. All iteration constraints are respected, and elements which cause maxCharacters to be exceded are queued for later retrieval.
