Method Detail

size

public int size()

degree

public int degree(long node)

Description copied from interface: AdjacencyList

Returns the degree of a node. Undefined behavior if the node does not exist.

Specified by:

degree in interface AdjacencyList

adjacencyCursor

public CompositeAdjacencyCursor adjacencyCursor(long node)

Description copied from interface: AdjacencyList

Create a new cursor for the target ids of the given node. The cursor is not expected to return correct property values. NOTE: Whether and how AdjacencyCursors will return properties is unclear. Undefined behavior if the node does not exist.

Specified by:

adjacencyCursor in interface AdjacencyList

adjacencyCursor

public CompositeAdjacencyCursor adjacencyCursor(long node,
                                                double fallbackValue)

Description copied from interface: AdjacencyList

Create a new cursor for the target ids of the given node. If the cursor cannot produce property values, it will yield the provided fallbackValue. NOTE: Whether and how AdjacencyCursors will return properties is unclear. Undefined behavior if the node does not exist.

Specified by:

adjacencyCursor in interface AdjacencyList

adjacencyCursor

public CompositeAdjacencyCursor adjacencyCursor(@Nullable
                                                @Nullable AdjacencyCursor reuse,
                                                long node)

Description copied from interface: AdjacencyList

Create a new cursor for the target ids of the given node. The cursor is not expected to return correct property values. NOTE: Whether and how AdjacencyCursors will return properties is unclear. The implementation might try to reuse the provided reuse cursor, if possible. That is not guaranteed, however, implementation may choose to ignore the reuse cursor for any reason. Undefined behavior if the node does not exist.

Specified by:

adjacencyCursor in interface AdjacencyList

                                                @Nullable AdjacencyCursor reuse,
                                                long node,
                                                double fallbackValue)

Description copied from interface: AdjacencyList

Create a new cursor for the target ids of the given node. If the cursor cannot produce property values, it will yield the provided fallbackValue. NOTE: Whether and how AdjacencyCursors will return properties is unclear. The implementation might try to reuse the provided reuse cursor, if possible. That is not guaranteed, however, implementation may choose to ignore the reuse cursor for any reason. Undefined behavior if the node does not exist.

Specified by:

adjacencyCursor in interface AdjacencyList

rawAdjacencyCursor

public AdjacencyCursor rawAdjacencyCursor()

Description copied from interface: AdjacencyList

Create a new uninitialized cursor. NOTE: In order to use the returned cursor AdjacencyCursor.init(long, int) must be called.

Specified by:

rawAdjacencyCursor in interface AdjacencyList

close

public void close()

Specified by:

close in interface AdjacencyList

Specified by:

close in interface java.lang.AutoCloseable
