Method Summary

Modifier and Type	Method	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.

Method Detail

setPickByProperty

public 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.

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.

Parameters:

edgeProperty -

pickingStrategyFunction -

setPickByLabel

public 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.

Parameters:

pickingStrategyFunction -

setPickByEdgeId

public PickingStrategyBuilder setPickByEdgeId(oracle.pgx.common.mutations.PickingStrategyFunction pickingStrategyFunction)

build

public oracle.pgx.common.mutations.MutationStrategy build()
                                                   throws java.util.concurrent.ExecutionException,
                                                          java.lang.InterruptedException

Builds a PickingStrategy.

Per default, it will pick any edge. To change this behavior, call either setPickByProperty or setPickByEdgeId beforehand.

Specified by:

build in class MutationStrategyBuilder<PickingStrategyBuilder>

Throws:

java.util.concurrent.ExecutionException

java.lang.InterruptedException
