Class HoldemHandGroupFactory

java.lang.Object
  org.pokersource.enumerate.HoldemHandGroupFactory

public class HoldemHandGroupFactory
extends java.lang.Object

Creates instances of HoldemHandGroup-implementing objects from their string representations. Use of this factory is preferred to directly calling the constructors of subclasses, as the factory maintains a cache of immutable instances.

Field Summary

private static java.util.HashMap	cache Cache of hand groups already instantiated.
private static java.lang.Class[]	groupClasses Set of registered classes that we know how to instantiate.

Constructor Summary

HoldemHandGroupFactory()

Method Summary

static HoldemHandGroup	getInstance(java.lang.String groupSpec) Tries to parse groupSpec into a hand group using the constructors of the list of known classes.
static HoldemHandGroup	getInstance(java.lang.String groupSpec, java.lang.Class gclass) Tries to parse groupSpec into a hand group using the gclass constructor.
private static HoldemHandGroup	tryGetInstance(java.lang.Class gclass, java.lang.String groupSpec) Try to parse groupSpec using class gclass.

Method Detail

tryGetInstance

private static HoldemHandGroup tryGetInstance(java.lang.Class gclass,
                                              java.lang.String groupSpec)

Try to parse groupSpec using class gclass. If parsing succeeds, returns new group object; if parsing fails, returns null; if something unexpected happens, throws a runtime exception.

getInstance

public static HoldemHandGroup getInstance(java.lang.String groupSpec,
                                          java.lang.Class gclass)

Tries to parse groupSpec into a hand group using the gclass constructor. If gclass fails to parse groupSpec, throws a runtime exception.

getInstance

public static HoldemHandGroup getInstance(java.lang.String groupSpec)

Tries to parse groupSpec into a hand group using the constructors of the list of known classes. If all known classes fail to parse groupSpec, throws a runtime exception.
