Method Details

add

public void add(long timestamp,
Chunk<T> chunk)

Specified by:

add in interface ModifiableMemory<T>

Parameters:

timestamp - the point in time at which the addition occurs (in the format returned by System.currentTimeMillis()

addAll

public void addAll(long timestamp,
Collection<Chunk<T>> chunks)

Specified by:

addAll in interface ModifiableMemory<T>

Parameters:

timestamp - the point in time at which the addition occurs (in the format returned by System.currentTimeMillis()

getChunks

public Collection<Chunk<T>> getChunks(long timestamp,
int maximumCount)

Description copied from interface: Memory

Returns a limited number of chunks from memory after sorting the chunks in descending order by activation.

TODO: Maybe also add an accessor that limits by a maximum activation.

Specified by:

getChunks in interface Memory<T>

Parameters:

timestamp - the point in time at which the access occurs (in the format returned by System.currentTimeMillis()

maximumCount - The maximum number of chunks to return.

Returns:

The collection containing up to maximumCount chunks sorted, from highest to lowest activation.
