Method Detail

validateUnique

static <T extends ReadGraphOption> void validateUnique(java.util.Collection<ReadGraphOption> options,
                                                       java.lang.Class<T> clazz,
                                                       java.lang.String errorMessage)

Validates a given option list to contain only one item of the specified type.

Parameters:

options - the list of options to validate

clazz - the type of option to look for

errorMessage - the error message to be thrown when validation fails

optimizeFor

static ReadGraphOption.OptimizedForOption optimizeFor(GraphOptimizedFor optimizedFor)

Creates an option, which specifies whether a graph should be optimized for read or update

Parameters:

optimizedFor - specifies what the graph should be optimized for (read or update)

Returns:

the option, which encapsulates the optimizedFor parameter

onMissingVertex

static ReadGraphOption.OnMissingVertexOption onMissingVertex(OnMissingVertex onMissingVertex)

Creates an option, which specifies the behavior when the source or destination vertex of an edge is missing

Parameters:

onMissingVertex - specifies the behavior when the source or destination vertex of an edge is missing

Returns:

the option, which encapsulates the onMissingVertex option

withParallelHintDegree

static ReadGraphOption.ParallelHintDegreeReadGraphOption withParallelHintDegree(int parallelHintDegree)

Creates an option, which specifies the parallel hint degree to use for internal queries

Parameters:

parallelHintDegree - specifies the parallel hint degree to use for internal queries

Returns:

the option, which encapsulates the parallelHintDegree option

synchronizable

static ReadGraphOption.SynchronizableOptionReadGraphOption synchronizable()

Creates an option, which specifies if a graph cannot be synchronized, PGX will throw an Exception
