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 interfaceAdjacencyList
-
adjacencyCursor
public CompositeAdjacencyCursor adjacencyCursor(long node)
Description copied from interface:AdjacencyList
Create a new cursor for the target ids of the givennode
. The cursor is not expected to return correct property values. NOTE: Whether and howAdjacencyCursor
s will return properties is unclear. Undefined behavior if the node does not exist.- Specified by:
adjacencyCursor
in interfaceAdjacencyList
-
adjacencyCursor
public CompositeAdjacencyCursor adjacencyCursor(long node, double fallbackValue)
Description copied from interface:AdjacencyList
Create a new cursor for the target ids of the givennode
. If the cursor cannot produce property values, it will yield the providedfallbackValue
. NOTE: Whether and howAdjacencyCursor
s will return properties is unclear. Undefined behavior if the node does not exist.- Specified by:
adjacencyCursor
in interfaceAdjacencyList
-
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 givennode
. The cursor is not expected to return correct property values. NOTE: Whether and howAdjacencyCursor
s will return properties is unclear. The implementation might try to reuse the providedreuse
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 interfaceAdjacencyList

rawAdjacencyCursor
public AdjacencyCursor rawAdjacencyCursor()
Description copied from interface:AdjacencyList
Create a new uninitialized cursor. NOTE: In order to use the returned cursorAdjacencyCursor.init(long, int)
must be called.- Specified by:
