  - init
```
public static HashCodeBuilder init()
```
    Init hash code builder.
    
    Returns:
    
    the hash code builder
  - init
```
public static HashCodeBuilder init(int initialOddNumber,
                                   int multiplierOddNumber)
```
    Init hash code builder.
    
    Parameters:
    
    initialOddNumber - the initial odd number
    
    multiplierOddNumber - the multiplier odd number
    
    Returns:
    
    the hash code builder
  - append
```
public HashCodeBuilder append(boolean value)
```
    Append a hashCode for a boolean.
    This adds 1 when true, and 0 when false to the hashCode.
    This is in contrast to the standard java.lang.Boolean.hashCode handling, which computes a hashCode value of 1231 for java.lang.Boolean instances that represent true or 1237 for java.lang.Boolean instances that represent false.
    This is in accordance with the Effective Java design.
    
    Parameters:
    
    value - the boolean to add to the hashCode
    
    Returns:
    
    this hash code builder
  - append
```
public HashCodeBuilder append(boolean[] array)
```
    Append a hashCode for a boolean array.
    
    Parameters:
    
    array - the array to add to the hashCode
    
    Returns:
    
    this hash code builder
  - append
```
public HashCodeBuilder append(byte value)
```
    Append a hashCode for a byte.
    
    Parameters:
    
    value - the byte to add to the hashCode
    
    Returns:
    
    this hash code builder
  - append
```
public HashCodeBuilder append(byte[] array)
```

public HashCodeBuilder append(char value)
```
    Append a hashCode for a char.

    Returns:
    
    this hash code builder
  - append
```
public HashCodeBuilder append(char[] array)
```
