Method Detail

addLevel

public B addLevel(int capacity,
                  double loadFactor)
           throws IllegalArgumentException

Adds a level with the specified capacity and load factor. The arguments have the same meaning as if the level was a RecencyEvictor.

Parameters:

capacity - the capacity of the added level

loadFactor - the load factor of the added level

Returns:

This builder.

Throws:

IllegalArgumentException - When capacity is negative or load factor is not between 0 and 1 inclusive.

addLevel

public B addLevel(int capacity)
           throws IllegalArgumentException

Adds a level with the specified capacity and the default load factor DEFAULT_LOAD_FACTOR. The arguments have the same meaning as if the level was a RecencyEvictor.

Parameters:

capacity - the capacity of the added level

Returns:

This builder.

Throws:

IllegalArgumentException - When capacity is negative.

addLevel

public B addLevel(double loadFactor)
           throws IllegalArgumentException

Adds a level with the default capacity DEFAULT_CAPACITY and the specified load factor. The arguments have the same meaning as if the level was a RecencyEvictor.

Parameters:

loadFactor - the load factor of the added level

Returns:

This builder.

Throws:

IllegalArgumentException - When load factor is not between 0 and 1 inclusive.

addLevel

public B addLevel()

Adds a level with the default capacity DEFAULT_CAPACITY and load factor DEFAULT_LOAD_FACTOR. The arguments have the same meaning as if the level was a RecencyEvictor.

Returns:

This builder.

build

public <E> NQEvictor<E> build()

Builds the NQEvictor with the added levels. If none were added, builds NQEvictor with one level with default capacity and load factor.

Type Parameters:

E - The type of the elements maintained by the evictor.

Returns:

The built NQEvictor

convertThis

protected abstract B convertThis()
