• Method Detail

  • get

    public T get()

    Returns the value of this variable for the current thread. If an entry doesn't yet exist for this variable on this thread, this method will create an entry, populating the value with the result of initialValue().

    Returns:

    the current value of the variable for the calling thread.

  • initialValue

    protected T initialValue()

    Provides the initial value of this variable for the current thread. The default implementation returns null.

    Returns:

    the initial value of the variable.

  • set

    public void set(T value)

    Sets the value of this variable for the current thread. If set to null, the value will be set to null and the underlying entry will still be present.

    Parameters:

    value - the new value of the variable for the caller thread.

  • remove

    public void remove()

    Removes the entry for this variable in the current thread. If this call is followed by a get() before a set(T), #get() will call initialValue() and create a new entry with the resulting value.
