TicTacToeMyHashMap.TTTHashString

java.lang.Object
- TicTacToeMyHashMap.TTTHashString

Enclosing class:

TicTacToeMyHashMap
```
private class TicTacToeMyHashMap.TTTHashString
extends java.lang.Object
```
A nested class within TicTacToeMyHashMap. This class was created to hold a String with an overridden hashCode method, specifically one that I created. The class holds a value, which is a String, and the size of the hash it is being used in. Currently, the class has limited function considering it is a nested class and as such will only be used within the above TicTacToeMyHashMap, which is why its functions are so limited.

- Field Detail
  - value
```
private java.lang.String value
```
    The String value of the TTTHashString. This object is meant to function as a String, but one with a customized hashCode, so this method is important.
  - sizeOfHash
```
private int sizeOfHash
```
    The size of the hash this String will go into which is important because it is a part of the custom hashCode method. This information will need to come from outside the program.
  - POWERS_OF_THREE
```
private final int[] POWERS_OF_THREE
```
    A lookup table with powers of three where the each spot holds three ^ index
  - SPACE
```
private static final char SPACE
```
    A char holding a space

- Method Detail
  - hashCode
```
public int hashCode()
```
    Returns a hash code for each winner to be stored. This hash code method will cause collisions because this method is focusing on being efficient with space. This class was created in order for the hash code to be overridden, so this method is important. This method is trying to balance storage and efficiency concerns, so it tries to keep a fairly low average chain length and number of empty spaces.
    
    Overrides:
    
    hashCode in class java.lang.Object
    
    Returns:
    
    an int hash code based off the hash algorithm I created
