All Implemented Interfaces:
Iterator<Connection>
public abstract class Connections extends PropertyIteratorBase implements Iterator<Connection>
Connections supports an iterator over a list of connections. Callers can use it to step through the list just once. If they want to parse the list again, they could use the copy/clone constructor to create a new iterator.

  • Constructor Details

    • Connections

      public Connections(int maxCacheSize)
      Typical Constructor creates an iterator with the supplied list of elements.
      Parameters:
      maxCacheSize - maximum number of elements that should be retrieved from the property server and cached in the element list at any one time. If a number less than one is supplied, 1 is used.

    • Connections

      public Connections(Connections template)
      Copy/clone constructor. Used to reset iterator element pointer to 0;
      Parameters:
      template - type-specific iterator to copy; null to create an empty iterator

  • Method Details

    • hasNext

      public boolean hasNext()
      The iterator can only be used once to step through the elements. This method returns a boolean to indicate if it has got to the end of the list yet.
      Specified by:
      hasNext in interface Iterator<Connection>
      Returns:
      boolean indicating whether there are more elements.

    • next

      public Connection next()
      Return the next element in the iteration.
      Specified by:
      next in interface Iterator<Connection>
      Returns:
      Connection next element object that has been cloned.

    • remove

      public void remove()
      Remove the current element in the iterator. (Null implementation since this iterator works off of cached elements from the property (metadata) server.)
      Specified by:
      remove in interface Iterator<Connection>

    • toString

      public String toString()
      Standard toString method.
      Overrides:
      toString in class Object
      Returns:
      print out of variables in a JSON-style
