	// Methods
	// ----------------------
	// Adds to the hash table from XML previously created by calling ToXmlSb.
	bool AddFromXmlSb(CkStringBuilderW &sbXml);

	// Adds or replaces an entry with the given key and integer value to the hash
	// table. Returns true if a new hash entry was added or replaced. Returns false
	// if an out-of-memory condition occurred.
	bool AddInt(const wchar_t *key, int value);

	// Adds URL query parameters into the hashtable. The queryParams has the form:
	// field1=value1&field2=value2&field3=value3... . It is assumed that the values are
	// URL encoded, and this method automatically URL decodes the values prior to
	// inserting into the hashtable.
	bool AddQueryParams(const wchar_t *queryParams);

	// Adds or replaces an entry with the given key and string value to the hash table.
	// Returns true if a new hash entry was added or replaced. Returns false if an
	// out-of-memory condition occurred.
	bool AddStr(const wchar_t *key, const wchar_t *value);

	// Removes all elements from the Hashtable.
	void Clear(void);

	// Removes all elements from the Hashtable and re-sizes with the specified capacity.
	// 
	// The capacity is the number of buckets in the hash table. In the case of a hash
	// collision , a single bucket stores multiple entries, which must be searched
	// sequentially. One rule of thumb is to set the capacity to twice the number of
	// expected items to be hashed. It's also preferable to set the capacity to a prime
	// number. (The 1st 10,000 prime numbers are listed here:
	// https://primes.utm.edu/lists/small/10000.txt )
	// 
	// The initial default capacity of the hash table is 521.
	// 
	bool ClearWithNewCapacity(int capacity);

	// Determines if a given key is contained within the hash table. Returns true if
	// the key exists, otherwise returns false.
	bool Contains(const wchar_t *key);

	// Determines if a given key is contained within the hash table. Returns true if
	// the key exists, otherwise returns false.
	bool ContainsIntKey(int key);

	// Appends the complete set of hashtable key strings to strTable.
	bool GetKeys(CkStringTableW &strTable);

	// Returns the integer value associated with the specified key. If the key is not
	// in the hash table, the return value is 0.
	int LookupInt(const wchar_t *key);

	// Returns the string value associated with the specified key.
	bool LookupStr(const wchar_t *key, CkString &outStr);
	// Returns the string value associated with the specified key.
	const wchar_t *lookupStr(const wchar_t *key);

	// Removes the entry with the specified key from the hash table. Returns true if
	// the key existed and was removed. Returns false if the key did not already
	// exist.
	bool Remove(const wchar_t *key);

	// Serializes the hash table to a query string such as
	// key1=value1&key2=value2&key3=value3 where each value is URL encoded.
