Binary Graph Collection Operators
This section provides an overview of binary graph collection operators, which consume two GraphCollections as input.
| Binary Graph Collection Operators |
|---|
| Union |
| Intersection |
| Difference |
| Equality |
Given two collections, the union operator creates a GraphCollection that includes all logical graphs of both input collections. Graph equality is based on their identifiers.
| Method | Description |
|---|---|
| union | Returns the union of both GraphCollections. |
TBD
Given two collections, the intersection operator creates a GraphCollection that includes all logical graphs that exist in both input collections. Graph equality is based on their identifiers.
| Method | Description |
|---|---|
| intersect | Returns the intersection of both GraphCollections. |
| intersectWithSmallResult | Returns the intersection of both GraphCollections. Alternate implementation that works faster if the other GraphCollection is small (e.g. fits in the workers main memory). |
TBD
Given two collections, the difference operator creates a GraphCollection that includes all logical graphs that are contained in that collection but not in the other. Graph equality is based on their identifiers.
| Method | Description |
|---|---|
| difference | Returns the difference of both GraphCollections. |
| differenceWithSmallResult | Returns the difference of both GraphCollections. Alternate implementation that works faster if the intermediate result (list of graph identifiers) is small (e.g. fits in the workers main memory). |
TBD
Given two collections, the equality operator determines whether they are equal. The operator is implemented by the GraphCollection. The equality operator takes another GraphCollection as its input and outputs a DataSet<Boolean> that contains a single boolean value.
| Method | Description |
|---|---|
| equalsByGraphIds | Compares IDs of the graph heads of the GraphCollections for equality. |
| equalsByGraphElementIds | Compares IDs of the vertices and edges of the GraphCollections for equality. |
| equalsByGraphElementData | Compares data of the vertices and edges of the GraphCollections for equality. |
| equalsByGraphData | Compares data of the vertices, edges and graph heads of the GraphCollections for equality. |
TBD
