Class KeyMap<T>

All Implemented Interfaces:
Serializable, Cloneable, Iterable<String>, Map<String,T>, SequencedMap<String,T>
Direct Known Subclasses:
AddressParser.ParameterMap

public class KeyMap<T> extends LinkedHashMap<String,T> implements Iterable<String>
The KeyMap object is used to represent a map of values keyed using a known string. This also ensures that the keys and the values added to this hash map can be acquired in an independent list of values, ensuring that modifications to the map do not have an impact on the lists provided, and vice versa. The key map can also be used in a fore each look using the string keys.

  • Constructor Details

    • KeyMap

      public KeyMap()
      Constructor for the KeyMap object. This creates a hash map that can expose the keys and values of the map as an independent List containing the values. This can also be used within a for loop for convenience.
  • Method Details

    • iterator

      public Iterator<String> iterator()
      This is used to produce an Iterator of values that can be used to acquire the contents of the key map within a for each loop. The key map can be modified while it is been iterated as the iterator is an independent list of values.
      Specified by:
      iterator in interface Iterable<T>
      Returns:
      this returns an iterator of the keys in the map
    • getKeys

      public List<String> getKeys()
      This is used to produce a List of the keys in the map. The list produced is a copy of the internal keys and so can be modified and used without affecting this map object.
      Returns:
      this returns an independent list of the key values
    • getValues

      public List<T> getValues()
      This is used to produce a List of the values in the map. The list produced is a copy of the internal values and so can be modified and used without affecting this map object.
      Returns:
      this returns an independent list of the values
