Method Detail

propertyToCopy

public HllSketchEntityGenerator propertyToCopy(String propertyToCopy)

Overrides:

propertyToCopy in class CardinalityEntityGenerator<org.apache.datasketches.hll.HllSketch>

propertiesToCopy

public HllSketchEntityGenerator propertiesToCopy(String... propertiesToCopy)

Description copied from class: CardinalityEntityGenerator

Copies the properties from the edge to the new entities.

IMPORTANT - it does not clone the property values. You could end up with an object being shared between multiple elements.

Overrides:

propertiesToCopy in class CardinalityEntityGenerator<org.apache.datasketches.hll.HllSketch>

Parameters:

propertiesToCopy - the properties to copy from the edge

Returns:

this

group

public HllSketchEntityGenerator group(String group)

Overrides:

group in class CardinalityEntityGenerator<org.apache.datasketches.hll.HllSketch>

cardinalityPropertyName

public HllSketchEntityGenerator cardinalityPropertyName(String cardinalityPropertyName)

Overrides:

cardinalityPropertyName in class CardinalityEntityGenerator<org.apache.datasketches.hll.HllSketch>

countProperty

public HllSketchEntityGenerator countProperty(String countProperty)

Overrides:

countProperty in class CardinalityEntityGenerator<org.apache.datasketches.hll.HllSketch>

edgeGroupProperty

public HllSketchEntityGenerator edgeGroupProperty(String edgeGroupProperty)

Overrides:

edgeGroupProperty in class CardinalityEntityGenerator<org.apache.datasketches.hll.HllSketch>

getToSketchFunction

public Function<Object,org.apache.datasketches.hll.HllSketch> getToSketchFunction()

Specified by:

getToSketchFunction in class CardinalityEntityGenerator<org.apache.datasketches.hll.HllSketch>
