Method Detail

memoryEstimation

public static org.neo4j.gds.core.utils.mem.MemoryEstimation memoryEstimation(long avgDegree,
                                                                             long nodeCount,
                                                                             int propertyCount)

of

public static ChunkedAdjacencyLists of(int numberOfProperties,
                                       long initialCapacity)

add

public void add(long index,
                long[] values,
                int start,
                int end,
                int valuesToAdd)

For memory efficiency, we reuse the values. They cannot be reused after calling this method.

Parameters:

values - values to write

start - start index in values

end - end index in values

add

public void add(long index,
                long[] values,
                long[][] allProperties,
                int start,
                int end,
                int valuesToAdd)

For memory efficiency, we reuse the values. They cannot be reused after calling this method.

Parameters:

values - values to write

allProperties - properties to write

start - start index in values and properties

end - end index in values and properties

valuesToAdd - the actual number of targets to import from this range

capacity

public long capacity()

contains

public boolean contains(long index)

consume

public void consume(ChunkedAdjacencyLists.Consumer consumer)
