Method Detail

getMergeTraversal

Traversal.Admin<S,Map> getMergeTraversal()

getMergeMapWithGValue

default Object getMergeMapWithGValue()

Gets the merge map from this step. If the map was originally passed as a GValue, that is returned directly. If it was originally passed as a Map or ConstantTraversal, then a Map is returned. Otherwise, the MergeMap is returned in Traversal form.

getOnCreateTraversal

Traversal.Admin<S,Map> getOnCreateTraversal()

getOnCreateMapWithGValue

default Object getOnCreateMapWithGValue()

Gets the onCreate map from this step. If the map was originally passed as a GValue, that is returned directly. If it was originally passed as a Map or ConstantTraversal, then a Map is returned. Otherwise, the onCreate is returned in Traversal form.

getOnMatchTraversal

Traversal.Admin<S,Map<String,?>> getOnMatchTraversal()

getOnMatchMapWithGValue

default Object getOnMatchMapWithGValue()

Gets the onMatch map from this step. If the map was originally passed as a GValue, that is returned directly. If it was originally passed as a Map or ConstantTraversal, then a Map is returned. Otherwise, the onMatch is returned in Traversal form.

isStart

boolean isStart()

isFirst

boolean isFirst()

isUsingPartitionStrategy

boolean isUsingPartitionStrategy()

reset

void reset()

getRequirements

Set<TraverserRequirement> getRequirements()

setMerge

void setMerge(Traversal.Admin<?,Map<Object,Object>> mergeMap)

setOnCreate

void setOnCreate(Traversal.Admin<?,Map<Object,Object>> onCreateMap)

setOnMatch

void setOnMatch(Traversal.Admin<?,Map<Object,Object>> onMatchMap)
