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 AdjacencyCursor 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 AdjacencyCursor adjacencyCursor(@Nullable @Nullable AdjacencyCursor reuse, 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. 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:
rawAdjacencyCursor
in interfaceAdjacencyList
-
propertyCursor
public PropertyCursor propertyCursor(long node, double fallbackValue)
Description copied from interface:AdjacencyProperties
Create a new cursor for the properties of the relationships of a givennode
. If the cursor cannot produce property values, it will yield the providedfallbackValue
. NOTE: Fallback behavior is not widely available and will be part of the next episode. Undefined behavior if the node does not exist.- Specified by:
propertyCursor
in interfaceAdjacencyProperties
-
propertyCursor
public PropertyCursor propertyCursor(PropertyCursor reuse, long node, double fallbackValue)
Description copied from interface:AdjacencyProperties
Create a new cursor for the properties of the relationships of a givennode
. If the cursor cannot produce property values, it will yield the providedfallbackValue
. NOTE: Fallback behavior is not widely available and will be part of the next episode. 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:

rawPropertyCursor
public PropertyCursor rawPropertyCursor()
Description copied from interface:AdjacencyProperties
Create a new uninitialized cursor. NOTE: In order to use the returned cursorPropertyCursor.init(long, int)
must be called.- Specified by:
rawPropertyCursor
in interfaceAdjacencyProperties
-
memoryInfo
public AdjacencyList.MemoryInfo memoryInfo()
Description copied from interface:AdjacencyList
Returns information about on heap and off heap memory usage of this adjacency list.- Specified by:
