Class PTListMap

java.lang.Object
  com.plumtree.uiinfrastructure.utils.PTListMap

public class PTListMap
extends java.lang.Object

A data structure that is equivalent to a list of hashtables or a 2D staggered array but simpler interface and with convenience methods to retrieve String and integers. Logical image of the data structure: [0][key][key2][key3]...[keyn] [1][key][key2][key3]...[keyn] [2][key][key2][key3]...[keym] Uses one hashtable internally for efficiency. Example: Setting data * PTListMap foo = new PTListMap(); int nIndex = foo.AddNewElement(); foo.AddElementToIndex(nIndex, "fooKey1", "fooValue"); foo.AddElementToIndex(nIndex, "fooKey2", new Integer(100) ); foo.AddElementToIndex(nIndex, "fooKey3", new FooClass() ); nIndex = foo.AddNewElement(); foo.AddElementToIndex(nIndex, "fooKey1", "fooValue"); foo.AddElementToIndex(nIndex, "fooKey2", new Integer(100) ); foo.AddElementToIndex(nIndex, "fooKey3", new FooClass() ); Getting data for ( int i = 0; i < foo.GetSize(); i++ ) { String strVal = foo.GetElementAsString(i, "fooKey1"); int nVal = foo.GetElementAsInt(i, "fooKey2"); Object oVal = int nVal = foo.GetElementAs(i, "fooKey3"); }
