Method Detail

setPropertyMergingStrategy

public MergingStrategyBuilder setPropertyMergingStrategy(java.lang.String propertyName,
                                                         oracle.pgx.common.mutations.MergingFunction mergingFunction)

Convenience method for setPropertyMergingStrategy(EdgeProperty, MergingFunction).

Parameters:

propertyName -

mergingFunction -

setPropertyMergingStrategy

public MergingStrategyBuilder setPropertyMergingStrategy(EdgeProperty edgeProperty,
                                                         oracle.pgx.common.mutations.MergingFunction mergingFunction)

Define a merging function for the given edge property. All properties, where no MergingFunction was defined will be merged using MergingFunction.MAX.

Parameters:

edgeProperty - EdgeProperty Note, merging of sets is not supported yet.

mergingFunction - MergingFunction.MAX, MergingFunction.MIN, or MergingFunction.SUM

setKeepUserDefinedEdgeKeys

public MergingStrategyBuilder setKeepUserDefinedEdgeKeys(boolean keepUserDefinedEdgeKeys)

If set to true, the user-defined edge keys are kept as far as possible. If multiple edges A and B are merged into one edge, a new key is generated for this edge.

By default, an edge key is kept if possible, i.e., the corresponding edge could be kept without merging it.

Parameters:

keepUserDefinedEdgeKeys -

setLabelMergingStrategy

public MergingStrategyBuilder setLabelMergingStrategy(oracle.pgx.common.mutations.LabelMergingFunction mergingFunction)

Define a merging function for the edge labels. By default, i.e., without calling this method, the labels will be merged using LabelMergingFunction.MAX.

Parameters:

mergingFunction -

build

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

Description copied from class: MutationStrategyBuilder

Builds the MutationStrategy with the chosen parameters. Parameters that were not set, are instantiated with default values.

Specified by:

build in class MutationStrategyBuilder<MergingStrategyBuilder>

Throws:

java.util.concurrent.ExecutionException

java.lang.InterruptedException
