public B capacity(int capacity)
           throws IllegalArgumentException

capacity - The capacity of the evictor.

Returns:

This builder.

Throws:

IllegalArgumentException - When the argument is negative.

loadFactor

public B loadFactor(double loadFactor)
             throws IllegalArgumentException

Load factor is the proportion of the capacity that should be achieved when evicting. Eviction is trying to reduce the number of elements in this evictor to capacity times load factor. Load factor must be between 0 and 1 inclusive!

If not called, load factor defaults to DEFAULT_LOAD_FACTOR.

Parameters:

loadFactor - The load factor of this evictor.

Returns:

This builder.

Throws:

IllegalArgumentException - When the argument is not between 0 and 1 inclusive.

public <E> Evictor<E> build()

convertThis

protected abstract B convertThis()
