public class PickingStrategyBuilder extends MutationStrategyBuilder<PickingStrategyBuilder>
Modifier and Type | Method and Description |
---|---|
oracle.pgx.common.mutations.MutationStrategy |
build()
Builds a PickingStrategy.
|
PickingStrategyBuilder |
setPickByEdgeId(oracle.pgx.common.mutations.PickingStrategyFunction pickingStrategyFunction) |
PickingStrategyBuilder |
setPickByLabel(oracle.pgx.common.mutations.PickingStrategyFunction pickingStrategyFunction)
If there are multiple edges between two vertices, the edge whose label satisfies the
PickingStrategyFunction will be picked. |
PickingStrategyBuilder |
setPickByProperty(EdgeProperty edgeProperty, oracle.pgx.common.mutations.PickingStrategyFunction pickingStrategyFunction)
If there are multiple edges between two vertices, the edge that satisfies the
PickingStrategyFunction will be picked. |
PickingStrategyBuilder |
setPickByProperty(java.lang.String propertyName, oracle.pgx.common.mutations.PickingStrategyFunction pickingStrategyFunction)
Convenience method for
setPickByProperty(EdgeProperty, PickingStrategyFunction) . |

public oracle.pgx.common.mutations.MutationStrategy build() throws java.util.concurrent.ExecutionException, java.lang.InterruptedException
Per default, it will pick any edge. To change this behavior, call either setPickByProperty or setPickByEdgeId beforehand.

will be picked.
For instance, pick the edge where property_1 is MAX. Note, if two or more properties could be chosen according to the PickingStrategyFunction
, only one of them is picked.
