Method Details

getDefaultLabel

protected String getDefaultLabel()

Specified by:

getDefaultLabel in class AbstractAddElementStepPlaceholder<S,Vertex,Event.VertexAddedEvent>

setLabel

public void setLabel(Object label)

Description copied from interface: AddElementStepContract

Sets the label(s) to assign to the element produced by this step. Accepts a single String, GValue<String>, or Traversal resolving to a String, or a Collection<Object> of two or more such values. Should behave identically to specifying the same value at construction time. Implementations may restrict calling this method more than once at their own discretion.

Specified by:

setLabel in interface AddElementStepContract<S,Vertex>

Overrides:

setLabel in class AbstractAddElementStepPlaceholder<S,Vertex,Event.VertexAddedEvent>

Parameters:

label - a String, GValue<String>, Traversal, or Collection<Object>

hasUserProvidedLabel

public boolean hasUserProvidedLabel()

Specified by:

hasUserProvidedLabel in interface AddVertexStepContract<S>

equals

public boolean equals(Object o)

Overrides:

equals in class AbstractAddElementStepPlaceholder<S,Vertex,Event.VertexAddedEvent>

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractAddElementStepPlaceholder<S,Vertex,Event.VertexAddedEvent>

clone

public AbstractAddVertexStepPlaceholder<S> clone()

Description copied from interface: Step

Cloning is used to duplicate steps for the purpose of traversal optimization and OLTP replication. When cloning a step, it is important that the steps, the cloned step is equivalent to the state of the step when Step.reset() is called. Moreover, the previous and next steps should be set to EmptyStep.

Specified by:

clone in interface Step<S,Vertex>

Overrides:

clone in class AbstractAddElementStepPlaceholder<S,Vertex,Event.VertexAddedEvent>

Returns:

The cloned step

supportsMultiProperties

protected boolean supportsMultiProperties()

Specified by:

supportsMultiProperties in class AbstractAddElementStepPlaceholder<S,Vertex,Event.VertexAddedEvent>
