Constructor Details

Alias

public Alias(T value)

Create a new alias with the provided value.

Parameters:

value - the initial value of the alias

Method Details

setValue

public void setValue(T value)

Set the alias to the provided value, overwriting any existing value.

Parameters:

value - the new value

getValue

public T getValue()

Get the current value of the alias.

Returns:

the current value, or null if the value has not been set

equals

public boolean equals(Object o)

Overrides:

equals in class Object

Parameters:

o - the alias to compare

Returns:

whether the aliases are equal

hashCode

public int hashCode()

Calculate the hashcode of the value of the alias. When the value is null, this will return 0.

Overrides:

hashCode in class Object

Returns:

the hashcode of the value of the alias
